Abstract：
Wild progenitors of Triticeae crops generally have long dormancy periods. Domesticated crops inherited these longer dormancy alleles from their wild progenitors, which have since been modified and selected during cultivation and utilization by humans. Thus, allelic combinations at different seed dormancy loci are currently represented in Triticeae germplasm preserved in seed repositories and gene banks as accessions and materials of breeding programs. Methods to evaluate seed dormancy are key to explore, analyze, and exploit optimal alleles in dormancy genes. Recent developments in genomics have accelerated the identification and analysis of seed dormancy loci in Triticeae species. Transgenic experiments have been conducted to validate if candidate genes affect seed dormancy and more recently have yielded an array of mutations derived from genome editing for practical applications. The information gathered on these seed dormancy loci provides a deeper knowledge of germplasm diversity and offers strategies to control seed dormancy in breeding programs in Triticeae crops.
摘要：
小麦属作物的野生祖细胞通常具有较长的休眠期。驯化作物从其野生祖先那里继承了这些更长的休眠等位基因，此后在人类的培养和利用过程中进行了修改和选择。因此，目前，在种子库和基因库中保存的小麦种质中代表了不同种子休眠位点的等位基因组合，作为育种计划的材料和材料。评估种子休眠的方法是探索的关键，分析,并利用休眠基因中的最佳等位基因。基因组学的最新进展加速了小麦种子休眠基因座的鉴定和分析。已经进行了转基因实验以验证候选基因是否影响种子休眠，并且最近已经产生了一系列源自基因组编辑的突变，用于实际应用。收集到的有关这些种子休眠基因座的信息提供了对种质多样性的更深入了解，并提供了在小麦作物育种计划中控制种子休眠的策略。
