摘要:

驯化和长期育种导致的遗传瓶颈效应显著降低了栽培棉花的遗传多样性,限制了其新品种开发和适应未来挑战的潜力。野生种质资源则作为重要的基因库,为改良栽培棉提供了丰富的遗传多样性。本文系统综述了棉花野生种质资源在遗传多样性研究、优异耐逆资源挖掘、控制复杂农艺性状的异源四倍体重复基因挖掘,以及杂交育种材料创制中的最新进展与挑战,并靶定了4个亟待解决的关键科学问题,作为推动野生棉资源高效利用和育种创新的重要方向。未来研究将进一步利用野生种质资源的优异基因,联合基因组学、转录组学、表观组学等多组学技术,揭示关键功能基因及其调控机制,破解光周期敏感性机制,并结合基因编辑技术,推动优异基因向栽培种快速导入,实现棉花育种的创新发展。

Abstract:

Domestication and long-term breeding have led to the genetic bottleneck effect that significantly reduces the genetic diversity of cultivated cotton, limiting its potential for the development of new varieties and its ability to adapt to future challenges. Wild germplasm resources, however, serving as an important gene pool, may provide abundant genetic diversity for cultivated cotton improvement. This review systematically summarizes the latest advances and challenges in the study of cotton wild germplasm resources, including genetic diversity research, the identification of superior stress-resistant resources, the exploration of homoeologous tetraploid repeat genes controlling complex agronomic traits, and the creation of hybrid breeding materials. It also identifies four critical scientific issues that need to be addressed to promote the efficient utilization and breeding innovation of wild cotton resources. Future research will further leverage the superior genes of wild germplasm, combining genomics, transcriptomics, epigenomics, and other multi-omics technologies to identify key functional genes and their regulatory mechanisms, decipher the mechanisms of photoperiod sensitivity, and, in conjunction with gene editing technologies, accelerate the transfer of superior genes into cultivated species, thereby driving innovation and development in cotton breeding.
