摘要
种子发育是被子植物繁殖的中心环节,涉及众多基因及其互作。新近的研究集中在雌雄基因组的差异表达、后生过程的控制机理和发育调控网络等方面。对胚和胚乳发育相关基因的研究,可使人们在分子水平上解析种子发育和无融合生殖的分子机制,更有效地开展植物种子产量和品质改良的基因工程。
Seed development, which involves in multiple genes and their interactions, is a central partof the reproductive process in angiosperms. Recent studies have highlighted the differential expres-sion between male and female genomes, the mechanism of epigenetic processes and the regulationnetwork of development. Studies on genes related to embryo and endosperm development are lead-ing us to an extensive understanding of the mechanisms of seed development and apomixis at themolecular level, which will benefits the research for yield and quality improvement of plant seeds viagenetic engineering.
