糖代谢在植物雄性生殖中起着至关重要的作用。花药和花粉发育过程中糖代谢缺陷常导致核不育。本文综述了糖代谢相关的核不育基因及其在植物花药和花粉发育过程中的作用，包括愈伤组织壁和初生壁的形成、内壁发育、花粉成熟和淀粉积累、花药开裂、花粉萌发和花粉管生长。基于生物信息学和RNA-SEQ分析，我们预测了112个可能的玉米糖代谢核不育基因，其中大部分在花药发育中后期有表达高峰。最后，我们概述了糖代谢核不育基因在作物杂交育种和制种中的潜在应用。这篇综述将加深我们对糖代谢途径在控制植物花粉发育和雄性育性方面的理解。(C)2021年中国作物科学学会和中国科学院作物科学研究所。爱思唯尔B.V.代表科爱通信有限公司制作和主办。
Sugar metabolism plays an essential role in plant male reproduction. Defects in sugar metabolism during anther and pollen development often result in genic male sterility (GMS). In this review, we summarize the recent progresses of the sugar metabolism-related GMS genes and their roles during plant anther and pollen development, including callose wall and primexine formation, intine development, pollen maturation and starch accumulation, anther dehiscence, and pollen germination and tube growth. We predict 112 putative sugar metabolic GMS genes in maize based on bioinformatics and RNA-seq analyses, and most of them have peak expression patterns during middle or late anther developmental stages. Finally, we outline the potential applications of sugar metabolic GMS genes in crop hybrid breeding and seed production. This review will deepen our understanding on sugar metabolic pathways in controlling pollen development and male fertility in plants.
