Tianlai Li is one of the earliest facility horticultural experts to study vegetables in solar greenhouse in China. The theory and method of rational daylighting, heat storage and thermal insulation design of solar greenhouse were pioneered, the structural optimization design software of solar greenhouse was developed, and the superior structural parameters of solar greenhouse in the area of 38-46 degrees north latitude were determined, and the fourth generation energy-saving solar greenhouse was first created. the daylighting rate of the greenhouse was increased from 73% to 86%, and the temperature difference between indoor and outdoor at night was increased from 25 ℃ to 39 ℃. The unheated production area of fruits and vegetables in winter moves northward from 40.5 degrees north latitude to 43.5 degrees (about 300 kilometers north). Compared with the traditional multi-span greenhouse, the equipment cost of the new energy-saving solar greenhouse is reduced by more than 55%, saving 60,80 tons of coal per mu. Professor Tianlai Li also explored the mechanism of main adverse growth obstacles of fruits and vegetables, developed the key techniques of fruit and vegetable cultivation under low temperature and low light, and established intensive seedlings, winter and spring cultivation, long-season cultivation and full-season cultivation model and technical system of fruits and vegetables in solar greenhouse in northern cold region, which set a precedent of 25000 kg per mu fruit and vegetable yield per mu in cold region above minus 28 ℃. It is three times the yield in the early 1990s. It has laid a solid technical foundation for the formation and development of vegetable industry in solar greenhouse in China. He has made an important contribution to the development of facility horticulture in China.

The past several decades have seen enormous progress in our understanding of angiosperm phylogeny and evolution. These studies have clarified the backbone of angiosperm phylogeny and revealed multiple deep level rapid radiations. But much of that understanding is based on sequencing of the plastid genome. Recent phylogenomic studies have provided a much needed nuclear genetic perspective revealing multiple instances of deep level incongruence between relationships based on plastid vs nuclear genetic data, suggesting ancient reticulation and lineage sorting during the many pulses of angiosperm radiation. Phylogenomic data have also demonstrated the crucial role that whole genome duplication (WGD) has played throughout angiosperm evolutionary history - WGD is frequently associated with episodes of rapid species diversification. Genomic studies have also shown that synteny is often highly conserved across deep angiosperm evolution. Finally, phylogenomic tools and workflows enable plant systematists to use small fragments of herbarium specimens to undertake truly massive phylogenomic studies both for enormous clades of plant life encompassing many thousands of species, as well as enabling studies of plant phylogenetic diversity of entire floras at continental scale.

Peach and almond are two closely related, intercompatible, Prunus species that are grown for their fruit and seed, respectively. Other Prunus crops are apricots, cherries or plums and ~200 wild relatives, many of which sexually inter-compatible, that share a small genome of ~0.25Gbp. “De novo” sequences of these genomes have been recently released and 26 of them are available in public databases. Peach and almond genomes are highly similar, but differ in many short structural variants and in the times of insertion of certain transposable elements. Given the high level of genetic variability of almond, it appears as a suitable donor of genes for the much less variable peach. The introgression of new genes into the elite peach commercial pool requires many backcross generations, a challenge for a species with a 3-4-year intergeneration period. We reduced them to 2-3 using the marker-assisted introgression (MAI) approach that we have tested in almond x peach crosses and that we are now expanding to other peach wild relatives. As a side result we have produced a collection of peach-almond near-isogenic lines, useful to characterize and dissect genetic variability. Two key genes for peach flesh fruit formation have been identified and are currently being introduced in the almond background to generate almond trees that yield peaches. In addition, we have developed a marker-based approach (“resynthesis”) to select for a pair of inbred lines that would generate a high-value partly-heterozygous genotype (a top-performing cultivar), which we are currently applying to peach and almond.

Rosa rugosa, commonly known as rugged rose, is a perennial ornamental shrub. It produces beautiful flowers with a mild fragrance and colorful seed pods. Unlike many other cultivated roses, R. rugosa adapts to a wide range of habitat types and harsh environmental conditions such as salinity, alkaline, shade, drought, high humidity, and frigid temperatures. Here, we produced and analyzed a high-quality genome sequence for R. rugosa to understand its ecology, floral characteristics and evolution. PacBio HiFi reads were initially used to construct the draft genome of R. rugosa, and then Hi-C sequencing was applied to assemble the contigs into 7 chromosomes. We obtained a 382.6 Mb genome encoding 39,704 protein-coding genes. The genome of R. rugosa appears to be conserved with no additional whole-genome duplication after the gamma whole-genome triplication (WGT), which occurred ~100 million years ago in the ancestor of core eudicots. Based on a comparative analysis of the high-quality genome assembly of R. rugosa and other high-quality Rosaceae genomes, we found a unique large inverted segment in the Chinese rose R. chinensis and a retroposition in strawberry caused by post-WGT events. We also found that floral development- and stress response signaling-related gene modules were retained after the WGT. Two MADS-box genes involved in floral development and the stress-related transcription factors DREB2A-INTERACTING PROTEIN 2 (DRIP2) and PEPTIDE TRANSPORTER 3 (PTR3) were found to be positively selected in evolution, which may have contributed to the unique ability of this plant to adapt to harsh environments. In summary, the high-quality genome sequence of R. rugosa provides genetic map for molecular breeding and enables comparative genomic studies of Rosa in the near future.

Anthocyanins are major pigments contributing to the flower color of ornamental plants, and the biosynthesis of anthocyanins has been widely reported to be controlled by SG6 subgroup MYB regulators, respectively, especially in eudicot plants. However, little consensus has been reached about functional discrepancies versus conservation among the SG6 MYB regulators as well as MBW complex from different plant lineages. In our study, we found that the MBW complex was highly evolutionarily conserved between tested monocot and eudicot plants, whereas the participating MYB regulators showed functional differences in transactivation capacity according to their activation domain. Floral flavonols also play pivotal roles in flower pigmentation as co-pigments, whereas the process of flavonol biosynthesis in late flower development stages and in mature flower tissues is poorly understood. In our study, we found that two FLS genes were shown to be expressed synchronously with the flower development-specific and tissue-specific biosynthesis of flavonols in Freesia hybrida, which were controlled by differential phylogenetic MYB regulators, i.e., SG7 MYB and FhMYB21L2, respectively. Interestingly, the non-SG7 MYB, FhMYB21L2, was found to be able to target and activate the expression of FhTPS1 gene, which encode a terpene synthase catalyzing the biosynthesis of the most abundant components of flower scents of Freesia cultivars.

Horticultural crops have enormous diversity in carotenoid content and composition, evolving from complicated and multifaceted regulatory mechanisms. Despite significant progress in our understanding of carotenoid metabolism, the control mechanisms are still not well understood. In this talk, I will report our recent results in the understanding of the regulatory control of carotenoid accumulation. Phytoene synthase (PSY) is the rate-limiting enzyme in the carotenoid biosynthetic pathway and its activity profoundly affects carotenoid content. By investigating tomato PSY enzyme family, we found great difference of enzyme activity with the PSY isozymes and identified the key amino acid residues responsible for the activity divergence. We examined the evolutionary features of these key residues toward high PSY activity for the potential of rationally designing PSY enzyme. Furthermore, we elucidated the mechanisms of maintaining the homeostasis of PSY in the plastids to assure optimal enzyme protein abundance for adequate carotenoid biosynthesis in plants. In addition, because of the critical role of chromoplasts for carotenoid accumulation in horticultural crops, we also investigated the machinery underlying chromoplast division, which controls chromoplast number and subsequently the metabolic sink strength for carotenoid accumulation. We documented the synergetic effects of simultaneously regulating biosynthetic activity and increasing storage sink capacity for carotenoid accumulation, which likely represents the basis for high carotenoid content in many horticultural crops.

Dioecy has been evolved in major lineages of land plants except ferns and hornworts. Sex determination is a major switch in plant evolution and during the life cycle of a plant species. Advancement of genomic technologies accelerated identification of candidate genes for sex determination in diecious plant species, leading to identification of sex determination genes from twelve species in eight angiosperm families. The mechanism for sex determination in each of these eight families is different and the function of candidate genes include transcription factors, functional enzymes, a Cytochrome P450, small RNAs, and genes involved in plant hormone biosynthesis, perception, and response. Two candidate genes for sex determination were identified in eight species of seven families, whereas a single candidate gene for sex determination is identified in four species of two families. In two families with candidate genes identified in multiple species, candidate genes for sex determination are different between two species in the genus Ficus in Moraceae, whereas the two-gene model and one-gene model for sex determination coexists in four species in two genera with the candidate gene in one-gene model shared in three species across two genera in Salicaceae. Candidate genes for sex determination could be conserved among some genera within a family, but are not conserved among angiosperm families. Identification of candidate genes for sex determination has to be carried out at the species level.

Considering the important economic value of viticulture, climate change is considered as a major problem, which may weaken this sector worldwide. Increases of temperature, longer and more intense water deficits, together with higher CO2 content, increases of soil salinity and reduced nutrient availability will be among the most relevant changes for grapevine development. However grapevine (Vitis spp.) is cultivated successfully in many different environments; therefore we may assume that it has evolved mechanisms which enable it to respond and adapt to different, and potentially limiting, environments. Owing to the huge genetic diversity within Vitis spp., the grapevine genome contains many alleles controlling these mechanisms that could be exploited to ensure the sustainability of viticulture in a changing climate. Over the past decade, there has been much progress in understanding the physiological and molecular mechanisms underlying grapevine responses to different environmental factors. Integrated approaches are also required to deliver relevant knowledge which can be used to design practical solutions for vineyards. Few examples of studies aiming at the identification of key mechanisms involved in the responses of grapevine to these factors will be presented.

New cultivars of rosaceous crops (including apple, peach, strawberry, cherry, and rose) need both disease resistance and superior horticultural quality for their commercial industries to sustainably supply consumers with quality of life-enhancing products. Until recently, rosaceous crop breeders lacked key knowledge and tools to fully implement DNA-informed breeding. A “chasm” existed between existing genomics and genetic information and the application of this knowledge in breeding. The RosBREED project was a collaborative, community-wide endeavor in the U.S. to bridge this chasm. Numerous successes were achieved in integrating DNA information routinely into breeding decisions, enhancing the efficiency and effectiveness of U.S. rosaceous crop breeding programs. All breeding germplasm levels were addressed, from pre-breeding generations to parents, seedling families, elite selections, and released cultivars. Large-effect quantitative trait loci (QTLs accounting for meaningful variation in key traits) were the focus. There were also successful applications of genome-wide selection (identifying superior individuals based on the correlation of genetic variation across entire genomes with performance levels of key traits) and G×E performance predictions (how individuals with certain sets of alleles are expected to perform in different growing environments). Additionally, DNA fingerprinting to ascertain identity, relatedness, and cultivar pedigrees was conducted. By the end of this 10-year effort, DNA-informed breeding had become the new “conventional” breeding approach for U.S. rosaceous crops. Foundational knowledge, skills, and resources were established in this project: an understanding of consumer and grower priorities for key trait levels, reference germplasm sets, standardized methods and metrics for phenotyping, new cost-effective SNP arrays, enhanced tools and practices for pedigree-based analysis, many newly discovered and validated QTLs, associated affordable DNA tests, decision-support tools for breeding programs, greater knowledge of distributions of valuable alleles in breeding programs and wild germplasm, and enhanced new germplasm. RosBREED’s legacy of sustained advances also includes a cohort of trainees in breeding and DNA information support – new professionals readily able to traverse the bridge in both directions, with integrated knowledge ranging from lab-based scientific discovery to applied genetics. Post-RosBREED, breeders’ two lowest-hanging fruit both involve understanding their elite germplasm. The first is DNA-informed identity and pedigree verification – ensuring parents and selections are what they should be and knowing from where their alleles were inherited. The second is marker-assisted parental selection – planning bi-parental crosses knowing the large-effect alleles carried by all possible parents. More reliable measurement of commercially relevant phenotypic variation and alignment with heritable components is critically needed for effective genetic improvement of many valuable traits. Other compelling research opportunities include conversion of knowledge about large-effect QTLs: identifying the functional alleles carried by each parent and developing more and refined DNA tests. For breeders to fully benefit from DNA information on their germplasm, genome-wide genetic variation needs to be understood and routinely accessed.

Productivity of citrus crop depends essentially on two premier facts, nutrient balance and biological activity. Different magnitude of microbial synergism with citrus cultivars aided in unlocking the productivity stagnation through improved efficacy of applied nutrients. The paradigm shift from purely inorganic to either organic fertilizers or combination involving chemical fertilizers along with organic fertilizers and microbial inoculants formed the basis for Integrated Soil Fertility Management (ISFM). Long term data(2007-19) accrued on response of organic manures versus inorganic fertilizers demonstrated that important soil quality indices like soil microbial diversity, soil microbial biomass nutrient (Cmic, Pmic, and Nmic), and organic carbon partitioning displayed significant changes, but without much difference in quantum of fruit yield. The efficacy of microbial consortium (Paneibacillus alvei (MF113275) Cheshire and Cheyne, Bacillus pseudomycoides (MF113272) Nakamura, Micrococcus yunnanesis (MF113274) Cohn, Acinetobacter radioresistens (MF113273) Nishimura and Aspergillus flavus (MF113270) Link) was tested successfully in both nurseries as well as well grown-up orchards through ISFM to cut down the rate of CO2 release compared to inorganic fertilizers for storing larger proportion of plant-derived C in long term pools in the soil and reducing the exposure of such stored C to lesser decomposition, in addition to better post-harvest shelf life of citrus fruits. Microbes mediated ISFM provided an understanding on mechanisms involved in C stabilization in soils for regulating soil C sequestration and associated nutrient dynamics under ISFM -based production system in citrus.
Our studies on crop specific microbial consortium, in combination with nutrients (organic or inorganic in nature) provided a much better insights with an added element of better labile pool of microbial (taxonomic, function, and metabolic diversity) and nutrient pool of the rhizosphere for stronger soil carbon sink ultimately. The concept of “rhizosphere hybridization” is, therefore, advocated to harness the value added benefit of nutrient -microbe synergy, besides providing dynamism to microbial consortium suiting to wide range of perennial fruits. Microbial consortium augered well with fertigation(biofertigation) well, as a pretreatment of soil before injecting soluble mineral fertilizers into the wetting zone of drippers in order to improve upon the fertilizer use efficiency. Our studies, hence, aided in developing a robust microbes-mediated module of ISFM for elevated production efficiency of citrus.

Opportunity and challenges of the agriculture scenario of the next decades will face increasing demand for secure food through approaches able to minimize the input to cultivations. In this frame, large panels of tomato varieties represent a valuable resource of traits of interest to consider for the improvement of varieties addressed for sustainable cultivation systems. Here we report comprehensive genotyping, phenotyping and genome-wide association studies (GWAS) using over 37K high quality SNPs obtained through double digest restriction-site associated DNA (dd-RADseq): a flexible and cost-effective strategy for providing in-depth insights into the genetic architecture of germplasm collections. Using this methodology, we investigated the genomic diversity of a panel of 288 diverse tomato (Solanum lycopersicum L.) accessions enriched in ‘da serbo’ (called ‘de penjar’ in Spain) long shelf life (LSL) materials (152 accessions) mostly originating from Italy and Spain. The rest of the materials originated from different countries and included landraces for fresh consumption, elite cultivars, heirlooms, and breeding lines. Model ancestry population structure and non-parametric hierarchical clustering have been inferred. Six genetic subgroups were revealed, clearly separating most LSL landraces, but also the Spanish germplasm, suggesting a subdivision of the population based on the type and geographical provenance. Linkage disequilibrium (LD) in the collection decayed very rapidly within <5 kb. We then investigated SNPs showing contrasted minor frequency allele (MAF) in LSL materials, resulting in the identification of high frequencies in this germplasm of several mutations in genes related to stress tolerance and fruit maturation, such as CTR1 and JAR1. For mapping loci controlling the variation of agronomic, fruit quality, and root architecture traits, we grew the collection under organic field trials.
A wide range of phenotypic diversity was observed in the studied collection, with highly significant differences encountered for most of the traits. A variable level of heritability was observed with values up to 69% for morphological traits while among agronomic ones, fruit weight showed values above 80%. Genotype by environment analysis highlighted the strongest genotypic effect for aboveground traits compared to root architecture, suggesting that the hypogeal part of tomato plants has a more complex genetic control. GWAS was performed by a compressed mixed linear model leading to 59 significantly associated loci, allowing the identification of novel genes related to flower and fruit characteristics. Most genomic associations fell into the region surrounding SUN, OVATE, and MYB gene families Six flower and fruit traits were associated with a single member of the SUN family (SLSUN31) on chromosome 11, in a region involved in the increase of fruit weight, locules number, and fruit fasciation. Furthermore, additional candidate genes for soluble solids content, fruit colour and shape were found near previously reported chromosomal regions, indicating the presence of synergic and multiple linked genes underlying the variation of these traits.
Results of this study highlight the presence of a genetic footprint of the ‘da serbo’/LSL germplasm selected in the Mediterranean basin giving new hints on the genetic basis of traits in underexplored germplasm grown under organic conditions. Moreover, we provide novel insights on LSL ‘da serbo’ germplasm as a promising source of alleles for tolerance to stresses providing a framework for the development of markers linked to candidate genes of interest to be used in genomics-assisted breeding in tomato, in particular under low-input and organic cultivation conditions.

Plant breeding often requires introducing a valuable trait from a wild species or distantly related species into an existing cultivar through crosses and backcrosses. Another major goal in plant breeding is to pyramid valuable traits. Breeding by crosses and backcrosses is labor intensive and extremely time consuming. CRISPR/Cas9-based gene drives were shown to trigger both zygotic conversion and biased transmission of traits in insects. Development of gene drives in plants thus can potentially revolutionize crop breeding by greatly reducing the time/generations needed for trait-stacking and for clean introduction of a value-added trait from wild relatives or distantly related species into an elite cultivar without introducing any linkage drags. Here we demonstrate that the canonical CRISPR/Cas9-based gene drives are able to cause zygotic conversion and to produce F1 plants that are homozygous at target locus while maintaining heterozygosity at all other loci. Moreover, we show that the Arabidopsis gene drives generate biased transmission of the preferred allele, bypassing the constraints of Mendelian genetics. Furthermore, we demonstrate that the gene drive element and target gene can be spatially separated in a trans-acting gene drive, which allows the removal of the gene drive elements after target genes are modified. The trans-acting gene drive was also able to convert heterozygous plants into homozygous plants through zygotic conversion. I will discuss the various potential applications of gene drives in plant breeding.

Systemic acquired resistance (SAR) is induced by activation of local defenses and confers broad spectrum resistance against different pathogens in plants. Early studies in tobacco identified salicylic acid (SA) as an essential signaling molecule for SAR. Using Arabidopsis as a model plant, how pathogen-induced SA is biosynthesized and perceived by plants was revealed. In Arabidopsis, pathogen-induced SA is produced via the isochorismate pathway and SA is perceived by two classes of receptors: NONEXPRESSER OF PR GENES 1 (NPR1) and NPR3/NPR4, which activate two parallel signaling pathways to stimulate the expression of defense-related genes and immunity. Recent studies identified N-hydroxypipecolic acid (NHP) as a key mobile signal for SAR. SA induces the expression of NHP biosynthesis genes and stimulates the production of NHP in local tissue. In turn, NHP induces SAR by promoting SA biosynthesis in distal tissue.

Cultivated strawberry (Fragaria x. ananassa) is an interspecific hybrid among two wild octoploid species; the Virginia strawberry (F. virginiana) and beach strawberry (F. chiloensis). Cultivars are highly sensitive to salinity, and seawater intrusion into aquifers is impacting the productivity of this crop in several important agricultural areas. Here we report a chromosome-scale assembly for F. chiloensis ‘Del Norte’ that is adapted to a high salinity environment – a lighthouse island off the coast of California. We identified two major quantitative trait loci (QTL) that encodes for high salinity tolerance using a genetic mapping population generated from crossing ‘Del Norte’ with a historically important cultivar ‘Camarosa’. Interestingly, both QTL were contributed by the same diploid progenitor subgenome. Gene functional classification analyses, combined with differential gene expression analysis following a salt treatment, identified several candidate genes previously characterized in other species to be involved in salinity tolerance. These findings and the new reference genome, combined with the strawberry 50K genotyping array, were sufficient to identify markers that could be used to guide molecular breeding efforts to develop new cultivars with superior salinity tolerance.
Elizabeth I. Alger is a PhD candidate in the Plant Breeding, Genetics and Biotechnology graduate program in the Edger lab at Michigan State University. Her research focuses on the factors influencing subgenome dominance in hybrid strawberry as well as salinity tolerance in cultivated and wild strawberry.
