中文摘要：

GDSL脂酶是指蛋白N＇端具有保守GDSL序列的、广泛存在于原核和真核生物的一类水解酶.植物GDSL脂酶是一个大的基因家族,家族成员间存在较大的结构和功能多样性,在植物生长发育、逆境胁迫和油脂代谢等生理活动中发挥重要的生物学功能.本文对植物GDSL脂酶家族成员的结构、分类、进化、表达与功能上研究进展进行较为全面的综述,并简要介绍了本实验室有关GDSL基因在油料作物种子油脂积累过程中的作用方面的研究进展.

英文摘要：

GDSL gene family is featured with a conserved GDSL motif at N＇ terminus and encode a variety of lipases that exist in various species from prokaryotic to eukaryotic.GDSL gene family in plant consists of a wide range of members that exhibit structural and functional divergences,playing important roles in plant physiological processes including development,stress response and lipid metabolism.In this review,we summarize the previous literatures about plant GDSL genes,with respects of their structural divergences,classification,evolutional changes,expression and functions.In particular,here we report our recent findings regarding to the role of some GDSL genes in seed fatty acid accumulation of oilseeds.
