摘要:

木薯是全球热区的重要粮食作物、经济作物和能源作物,但其生物学研究和育种进展落后于主要粮食作物,分子育种是木薯遗传改良的重要驱动力,挖掘木薯重要性状相关基因是实现其传统育种向分子育种转变的基础和前提。本文系统地总结了木薯株型、产量、品质、抗逆等性状基因以及相关基因功能表征的最新进展,并指出构建自交分离群体和多组学整合是未来挖掘木薯关键基因的重要手段。本文拟为推进功能基因组研究成果应用于木薯育种技术体系建设提供参考,为木薯遗传改良提供理论指导。

Abstract:

Cassava(Manihot esculenta Crantz)is an important food crop, cash crop and energy crop in global tropical regions, but the biology research and breeding progress have lagged behind major food crops. Molecular breeding is the important driving force for cassava genetic improvement. Discovery the genes related to important traits is the foundation and premise for the transformation from traditional breeding to molecular breeding. In this paper, systematically, we recapitulate recent progress on the genes related to the traits, such as plant morphology, yield, tuber quality, stress resistance, in cassava, also functional characterization of some genes. We further point out that both of constructing self-crossing population and multiple-omics data integrated are important ways to discovery the key genes in cassava in the future. This paper aims to provide reference for promoting the application of results of functional genome studies in the construction of cassava breeding technology system, and provide theoretical guidance for cassava genetic improvement.
