Rice bean (Vigna umbellata) is an underexploited domesticated legume crop consumed for dietary protein in Asia, yet little is known about the genetic diversity of this species. Here, we present a high-quality reference genome for a rice bean landrace (FF25) built using PacBio long-read data and a Hi-C chromatin interaction map, and assess the phylo...

A narrow genetic basis in modern cultivars and strong linkage disequilibrium in peach ( Prunus persica ) has restricted resolution power for association studies in this model fruit species, thereby limiting our understanding of economically important quality traits including fruit flavor. Here, we present a high-quality genome assembly for a Chines...

Background Structural variations (SVs), a major resource of genomic variation, can have profound consequences on phenotypic variation, yet the impacts of SVs remain largely unexplored in crops. Results Here, we generate a high-quality de novo genome assembly for a flat-fruit peach cultivar and produce a comprehensive SV map for peach, as a high pr...

... Previous studies have reported several QTLs for adaptation and yield component-related traits using linkage mapping based on biparental populations in rice bean 11,29 . However, the resolution and sensitivity have been limited by the small number of markers and genetic recombination, thus making it difficult to reveal the genetic mechanism of these traits and/or to develop breeding markers 30,31 . Genome-wide association studies (GWAS) have been successfully applied in crops for the efficient identification of favorable alleles/ haplotypes or causal variants/genes underlying complex traits as this strategy could simultaneously detect many natural allelic variations using a diverse germplasm panel 32,33 . ...
... In addition, the structural variation of large segments is also considered to have an important impact on plant characters. As found in maize, the expression level of Zm00015a037064 may be regulated by a 1794 bp SV [10]; while a 1.67 Mb inversion downstream of a PpOFP1 gene can lead to changes in peach fruit shape [11,12]. ...
