Cherries are one of the economically important fruit crops in the Rosaceae family, Prunus genus. As the first fruits of the spring season in the northern hemisphere, their attractive appearance, intensely desirable tastes, high nutrients content and consumer-friendly size captivate consumers worldwide. In the past 30 years, although cherry geneticists and breeders have greatly progressed in understanding the genetic and molecular basis underlying fruit quality, adaptation to climate change, and biotic and abiotic stress resistance, the utilization of cherry genomic data in genetics and molecular breeding has remained limited to date. Here, we thoroughly investigated recent discoveries in constructing genetic linkage maps, identifying quantitative trait loci (QTLs), genome-wide association studies (GWAS), and validating functional genes of edible cherries based on available de novo genomes and genome resequencing data of edible cherries. We further comprehensively demonstrated the genetic architecture of the main agronomic traits of edible cherries by methodically integrating QTLs, GWAS loci, and functional genes into the identical reference genome with improved annotations. These collective endeavors will offer new perspectives on the availability of sequence data and the construction of an interspecific pangenome of edible cherries, ultimately guiding cherry breeding strategies and genetic improvement programs, and facilitating the exploration of similar traits and breeding innovations across Prunus species.

食用樱桃主要农艺性状遗传结构的基因组和综合基因组见解


樱桃是蔷薇科李属的重要经济水果作物之一。作为北半球春季的第一批水果，其诱人的外观、令人向往的口味、高营养含量和适合消费者的尺寸吸引了全世界的消费者。在过去的30年里，尽管樱桃遗传学家和育种家在了解果实品质的遗传和分子基础、适应气候变化以及生物和非生物胁迫抗性方面取得了很大进展，但樱桃基因组数据在遗传学和分子育种中的利用仍然存在仅限于日期。在这里，我们深入研究了在构建遗传连锁图谱、识别数量性状位点（QTL）、全基因组关联研究（GWAS）以及基于现有的食用樱桃从头基因组和基因组重测序数据验证食用樱桃功能基因方面的最新发现。 。我们通过有条不紊地将QTL、GWAS位点和功能基因整合到具有改进注释的相同参考基因组中，进一步全面展示了食用樱桃主要农艺性状的遗传结构。这些集体努力将为序列数据的可用性和食用樱桃种间全基因组的构建提供新的视角，最终指导樱桃育种策略和遗传改良计划，并促进李属物种相似性状的探索和育种创新。
