Abstract

Well-coordinated flower development is crucial for successful fertility and prosperity of their species. Lipid is an emerging multifunctional component which plays pivotal roles in various aspects of plant development. However, the involvement of lipids in flower development is yet to be characterized comprehensively. By exploiting the novel system to synchronize flower development in Arabidopsis, a global stage-specific profiling of polar glycerolipids and phosphoinositides was carried out together with transcriptomic analyses on relevant lipid biosynthetic genes. The result showed that each lipid class showed dynamic changes, and gene expression pattern was clearly categorized into several groups. On the basis of global analyses, functional link between glycerolipids and flower development will be presented.
