3Whole-genome resequencing of Cucurbita pepo morphotypes to discover genomic variants associated with morphology and horticulturally valuable traits显示文摘Cucurbita pepo contains two cultivated subspecies,each of which encompasses four fruit-shape morphotypes(cultivar groups).The Pumpkin,Vegetable Marrow,Cocozelle,and Zucchini Groups are of subsp.pepo and the Acorn,Crookneck,Scallop,and Straightneck Groups are of subsp.ovifera.Recently,a de novo assembly of the C.pepo subsp.pepo Zucchini genome was published,providing insights into its evolution.To expand our knowledge of evolutionary processes within C.pepo and to identify variants associated with particular morphotypes,we performed wholegenome resequencing of seven of these eight C.pepo morphotypes.We report for the first time whole-genome resequencing of the four subsp.pepo(Pumpkin,Vegetable Marrow,Cocozelle,green Zucchini,and yellow Zucchini)morphotypes and three of the subsp.ovifera(Acorn,Crookneck,and Scallop)morphotypes.A high-depth resequencing approach was followed,using the BGISEQ-500 platform that enables the identification of rare variants,with an average of 33.5X.Approximately 94.5%of the clean reads were mapped against the reference Zucchini genome.In total,3,823,977 high confidence single-nucleotide polymorphisms(SNPs)were identified.Within each accession,SNPs varied from 636,918 in green Zucchini to 2,656,513 in Crookneck,and were distributed homogeneously along the chromosomes.Clear differences between subspecies pepo and ovifera in genetic variation and linkage disequilibrium are highlighted.In fact,comparison between subspecies pepo and ovifera indicated 5710 genes(22.5%)with Fst>0.80 and 1059 genes(4.1%)with Fst=1.00 as potential candidate genes that were fixed during the independent evolution and domestication of the two subspecies.Linkage disequilibrium was greater in subsp.ovifera than in subsp.pepo,perhaps reflective of the earlier differentiation of morphotypes within subsp.ovifera.Some morphotype-specific genes have been localized.Our results offer new clues that may provide an improved understanding of the underlying genomic regions involved in the independent evolution and domestication of the two subspecies.Comparisons among SNPs unique to particular subspecies or morphotypes may provide candidate genes responsible for traits of high economic importance.Aliki Xanthopoulou Javier Montero-Pau Ifigeneia Mellidou Christos Kissoudis JoséBlanca Belén Picó Aphrodite Tsaballa Eleni Tsaliki Athanasios Dalakouras Harry S.Paris Maria Ganopoulou Theodoros Moysiadis Maslin Osathanunkul Athanasios Tsaftaris Panagiotis Madesis Apostolos Kalivas Ioannis Ganopoulos 2019Horticulture Research2019,6,1:1

6Whole genome re-sequencing of sweet cherry(Prunus avium L.)yields insights into genomic diversity of a fruit species显示文摘Sweet cherries,Prunus avium L.(Rosaceae),are gaining importance due to their perenniallity and nutritional attributes beneficial for human health.Interestingly,sweet cherry cultivars exhibit a wide range of phenotypic diversity in important agronomic traits,such as flowering time and defense reactions against pathogens.In this study,wholegenome resequencing(WGRS)was employed to characterize genetic variation,population structure and allelic variants in a panel of 20 sweet cherry and one wild cherry genotypes,embodying the majority of cultivated Greek germplasm and a representative of a local wild cherry elite phenotype.The 21 genotypes were sequenced in an average depth of coverage of 33.91×.and effective mapping depth,to the genomic reference sequence of‘Satonishiki’cultivar,between 22.21×to 36.62×.Discriminant analysis of principal components(DAPC)with SNPs revealed two clusters of genotypes.There was a rapid linkage disequilibrium decay,as the majority of SNP pairs with r2 in near complete disequilibrium(>0.8)were found at physical distances less than 10 kb.Functional analysis of the variants showed that the genomic ratio of non-synonymous/synonymous(dN/dS)changes was 1.78.The higher dN frequency in the Greek cohort of sweet cherry could be the result of artificial selection pressure imposed by breeding,in combination with the vegetative propagation of domesticated cultivars through grafting.The majority of SNPs with high impact(e.g.,stop codon gaining,frameshift),were identified in genes involved in flowering time,dormancy and defense reactions against pathogens,providing promising resources for future breeding programs.Our study has established the foundation for further large scale characterization of sweet cherry germplasm,enabling breeders to incorporate diverse germplasm and allelic variants to fine tune flowering and maturity time and disease resistance in sweet cherry cultivars.Aliki Xanthopoulou Maria Manioudaki Christos Bazakos Christos Kissoudis Anna-Maria Farsakoglou Evangelos Karagiannis Michail Michailidis Chrysanthi Polychroniadou Antonios Zambounis Konstantinos Kazantzis Athanasios Tsaftaris Panagiotis Madesis Filippos Aravanopoulos Athanassios Molassiotis Ioannis Ganopoulos 2020Horticulture Research2020,7,1:0
