栗子（Castanea）是东亚和南欧的主要坚果作物，在温带坚果作物中是独一无二的，因为收获的种子是淀粉而不是油。板栗在中国已经种植了3000多年，所以人工选择很可能影响了果园种植的板栗的基因组。中国板栗（Castanea mollissima Blume）驯化的遗传学也是杂交美国板栗育种者感兴趣的，特别是如果中国板栗的低生长，分枝习性，阻碍美国板栗恢复，部分是人工选择的结果。我们对野生板栗和果园板栗的基因组进行了重测序，并基于汇集的全基因组SNP数据集确定了选择性扫描。我们提出了板栗驯化的候选基因位点，并讨论了候选位点的潜在表型效应，其中一些可能是有用的基因，在亚洲和北美的板栗改良。选择性扫描包括预测的基因可能与花的物候和发展，果实成熟，和次生代谢，并包括一些基因同源的驯化候选人在其他木本植物。
Chestnuts (Castanea) are major nut crops in East Asia and southern Europe, and are unique among temperate nut crops in that the harvested seeds are starchy rather than oily. Chestnut species have been cultivated for three millennia or more in China, so it is likely that artificial selection has affected the genome of orchard-grown chestnuts. The genetics of Chinese chestnut (Castanea mollissima Blume) domestication are also of interest to breeders of hybrid American chestnut, especially if the low-growing, branching habit of Chinese chestnut, an impediment to American chestnut restoration, is partly the result of artificial selection. We resequenced genomes of wild and orchard-derived Chinese chestnuts and identified selective sweeps based on pooled whole-genome SNP datasets. We present candidate gene loci for chestnut domestication and discuss the potential phenotypic effects of candidate loci, some of which may be useful genes for chestnut improvement in Asia and North America. Selective sweeps included predicted genes potentially related to flower phenology and development, fruit maturation, and secondary metabolism, and included some genes homologous to domestication candidates in other woody plants.
