Abstract:

The utilization of male sterile lines for seed production represents an effective strategy for exploiting heterosis in self-pollinating crops such as wheat and rice. ABCG transporters, a large subfamily of ABC transporters, play integral roles in various biological processes, including the regulation of male fertility. This review examines the structural characteristics of ABC transporters, emphasizes the critical role of ABCG transporters in regulating the development of the pollen wall and anther cuticle, and discusses the current state of research on ABCG transporters, along with future research prospects. The aim of this review is to enhance our understanding of the involvement of ABCG transporters in the regulation of plant male sterility, thereby providing a theoretical basis for the cross-breeding of self-pollinated crops.

摘要：

利用雄性不育系制种是利用杂种优势的最有效的途径，尤其对小麦（Triticum aestivum L.）、水稻（Oryza sativa L.）等自花授粉作物的杂种优势利用具有十分重要的意义。ABCG（ATP-binding cassette G transporter）转运蛋白属于ABC（ATP-binding cassette transporter）转运蛋白中的一个大亚族，参与植物各种生物过程，包括调控雄性育性。本文概述了ABC转运蛋白的特点与分类，并系统阐述了ABCG转运蛋白参与调控植物花粉壁和花药角质层发育的研究现状，同时也对ABCG转运蛋白目前研究所存在的问题提出了建议，并对后续的研究进行了展望。
