| 1 | Genome assembly of wild loquat (Eriobotrya japonica) and resequencing provide new insights into the genomic evolution and fruit domestication in loquat显示文摘Wild loquats(Eriobotrya japonica Lindl.)provide remarkable genetic resources for studying domestication and breeding improved varieties.Herein,we generate the first high-quality chromosome-level genome assembly of wild loquat,with 45791 predicted proteincoding genes.Analysis of comparative genomics indicated that loquat shares a common ancestor with apple and pear,and a recent whole-genome duplication event occurred in loquat prior to its divergence.Genome resequencing showed that the loquat germplasms can be distinctly classified into wild and cultivated groups,and the commercial cultivars have experienced allelic admixture.Compared with cultivated loquats,the wild loquat genome showed very few selected genomic regions and had higher levels of genetic diversity.However,whole-genome scans of selective sweeps were mainly related to fruit quality,size,and f lesh color during the domestication process.Large-scale transcriptome and metabolome analyses were further performed to identify differentially expressed genes(DEGs)and differentially accumulated metabolites(DAMs)in wild and cultivated loquats at various fruit development stages.Unlike those in wild loquat,the key DEGs and DAMs involved in carbohydrate metabolism,plant hormone signal transduction,f lavonoid biosynthesis,and carotenoid biosynthesis were significantly regulated in cultivated loquats during fruit development.These high-quality reference genome,resequencing,and large-scale transcriptome/metabolome data provide valuable resources for elucidating fruit domestication and molecular breeding in loquat. | Danlong Jing Xinya Liu Qiao He Jiangbo Dang Ruoqian Hu Yan Xia Di Wu Shuming Wang Yin Zhang Qingqing Xia Chi Zhang Yuanhui Yu Qigao Guo Guolu Liang | 2023 | Horticulture Research2023，10，2： | 0 |
