Abstract: The advance in mobilization of seed storage lipids was reviewed in this paper. There are different hydrolysis pathways of storage lipids in different seeds. It has now been proposed that there are three possible pathways for mobilization of storage lipids in seeds: direct lipase hydrolysis, acyl-CoA-diacylglycerol acyltransferase pathway, and lipoxygenase pathway. The first two pathways are independent of lipoxygenase. These 3 pathways might co-exist during the seed germination. However, there is no any knowledge about which of the 3 pathways is mainly responsible for, and about what is the differences of plants species in the storage lipid hydrolysis. Moreover, all of these 3 pathways have not been confirmed directly by genetic evidence.
