Abstract

Over time, wild crops have been domesticated by humans, and the knowledge gained from parallel selection and convergent domestication-related studies in cereals has contributed to current techniques used in molecular plant breeding. Sorghum (Sorghum bicolor (L.) Moench) is the world’s fifth-most popular cereal crop and was one of the first crops cultivated by ancient farmers. In recent years, genetic and genomic studies have provided a better understanding of sorghum domestication and improvements. Here, we discuss the origin, diversification, and domestication processes of sorghum based on archeological discoveries and genomic analyses. This review also comprehensively summarized the genetic basis of key genes related to sorghum domestication and outlined their molecular mechanisms. It highlights that the absence of a domestication bottleneck in sorghum is the result of both evolution and human selection. Additionally, understanding beneficial alleles and their molecular interactions will allow us to quickly design new varieties by further de novo domestication.

高粱驯化的遗传结构和分子调控。

随着时间的推移，野生作物已经被人类驯化，从谷物的平行选择和趋同驯化相关研究中获得的知识为目前用于分子植物育种的技术做出了贡献。高粱（Sorghum bicolor（L.）Moench）是世界上第五大最受欢迎的谷物作物，也是古代农民最早种植的作物之一。近年来，遗传和基因组研究为高粱的驯化和改良提供了更好的了解。在这里，我们根据考古发现和基因组分析讨论高粱的起源、多样化和驯化过程。本文还全面综述了高粱驯化相关关键基因的遗传基础，并概述了其分子机制。它强调，高粱没有驯化瓶颈是进化和人类选择的结果。此外，了解有益的等位基因及其分子相互作用将使我们能够通过进一步的从头驯化快速设计新品种。
