| 英文摘要 | Genetic studies on cold tolerance at the reproductive stage in rice could lead to significant reductions in yield losses. However, knowledge about the genetic basis and adaptive differentiation, as well as the evolution and utilization of the underlying natural alleles, remains limited. Here, 580 rice accessions in two association panels were used to perform genome-wide association study, and 156 loci associated with cold tolerance at the reproductive stage were identified.Os01g0923600andOs01g0923800were identified as promising candidate genes inqCTB1t, a major associated locus. Through population genetic analyses, 22 and 29 divergent regions controlling cold adaptive differentiation inter-subspecies (Xian/IndicaandGeng/Japonica) and intra-Geng,respectively, were identified. Joint analyses of four cloned cold-tolerance genes showed that they had different origins and utilizations under various climatic conditions.bZIP73andOsAPX1differentiating inter-subspecies evolved directly from wild rice, whereas the novel mutationsCTB4aandCtb1arose inGengduring adaptation to colder climates. The cold-tolerantGengaccessions have undergone stronger selection under colder climate conditions than other accessions during the domestication and breeding processes. Additive effects of dominant allelic variants of four identified genes have been important in adaptation to cold in modern rice varieties. Therefore, this study provides valuable information for further gene discovery and pyramiding breeding to improve cold tolerance at the reproductive stage in rice. |
