LAFL基因在种子发育和萌发中的功能
|
摘要
植物种子是人类粮食和家畜饲料的主要营养来源。种子的营养价值很大程度上依赖于在发育阶段积累的储藏物质,包括蛋白质、脂类等。LAFL基因(LEC1、ABI3、FUS3和LEC2)编码的转录因子从多层面调控种子发育,包括胚胎发生和储藏物质的积累过程。这些因子通过与其他因子间的相互作用形成复杂的调控网络,调控胚胎发生和种子成熟之间的转换以及成熟种子和发芽之间的转换。本文综述了LAFL基因在种子发育、萌发等过程中的作用的最新研究进展。
Plant seeds are a major source of nutrients for human and animal. The nutritive value of seeds is largely due to storage products that accumulated during seed development, including proteins and lipids. The LAFL genes(LEC2, ABI3, FUS3 and LEC1) encoding transcription factors regulate seed development including embryogenesis and accumulation of storage compounds. These transcription factors form a complex network with other players to control the switch between embryo development and seed maturation, and between seed maturation and germination. This paper reviews the latest research progress of LAFL genes in seed development and germination.
