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
