摘要:

脂类是生物体内的最重要物质之一。脂质运输是脂质代谢过程中重要环节。植物中参与脂质运输的蛋白质家族主要有三类:脂质转移蛋白(lipid transfer proteins, LTPs)、三磷酸腺苷结合盒转运蛋白(ATP- binding cassette transporter, ABC transporter) 和酰基辅酶A 结合蛋白(acyl- coenzyme A- binding proteins, ACBPs)。由于具有不同的亚细胞定位,这些脂类转运蛋白在脂类代谢过程中发挥着不同的作用。近期研究显示,除了保守的脂质转运功能,这三类脂类转运蛋白还不同程度地参与生长发育和胁迫响应。为进一步深入了解脂质运输在植物生长发育和胁迫响应过程中的作用机制,总结了以上三类脂类转运蛋白家族的结构、分类和不同植物中的亚细胞定位,并着重对脂质运输在生长发育和胁迫响应中的功能进行了整理。尽管大量证据显示这三类脂类转运蛋白在生长发育和胁迫响应中发挥作用,但是,只有少数研究说明脂质运输在其中发挥重要作用,而这些研究多集中在对ACBPs家族的研究中。

Abstract:

Lipid is one of the most essential substances in an organism. Lipid trafficking is an important process within lipid metabolism. There are three types of protein families involved in lipid trafficking in plant:lipid transfer proteins (LTPs), ATP-binding cassette (ABC) transporters and acyl-coenzyme A (CoA)-binding proteins (ACBPs). Due to the differences in subcellular localization, these three protein families function differently in lipid metabolism. Recent findings show that aside from conserved lipid transport ability, these proteins are also involved in development and stress responses to a different extent. To further understand the functional mechanism of lipid trafficking in development and stress responses, the structure, classification and subcellular localization of these proteins in different plant species were summarized and the function of lipid trafficking in development and stress responses was emphasized. Although much evidence show that these proteins involved in development and stress responses, a few of them indicate that lipid trafficking plays important roles in it, and most of the relevant findings focus on the studies of ACBPs.

Key words: lipid trafficking, lipid transfer proteins (LTPs), ATP- binding cassette transporter (ABC transporter), Acyl-CoA-binding protein (ACBPs), function
