All about Plant Lipid Droplets: Biogenesis, Metabolic Engineering, and Stress Signaling

About this Research Topic

Lipid droplets (LDs) are essential organelles to deposit neutral lipids, triacylglycerols (TAGs) as physiological sources, including energy and lipids for membrane biosynthesis in plants. Due to LDs being most abundant in oilseeds, these LDs have been well studied regarding biogenesis and metabolic engineering to increase biofuels. The functional study of these LDs have received less attention, even though LDs are present in non-seed tissues. Recently, to develop a time- and cost-effective method for metabolic engineering using LDs, scientists are extending the materials from oilseeds to vegetative tissues. In addition, lipophagy and stress signaling, along with LDs, are emerging fields to understand plant LD dynamics.

The aim of this Research Topic is to gather key contributions providing new insights into lipid droplets function and dynamics in whole plant tissues. We welcome all article types including Original Research, Reviews, Mini Reviews, Methods, and Opinions falling under the following topics:

- LD biogenesis including LD formation, maintenance, and turnover in plants
- Metabolic engineering of LD in oilseeds and non-oil seeds
- LD regulation by autophagy
- LD’s function related to abiotic and biotic stress signaling


Keywords: LD Dynamics, LD Biogenesis, LD Metabolic Engineering, LD-Stress Signaling, Lipophagy


Important Note: All contributions to this Research Topic must be within the scope of the section and journal to which they are submitted, as defined in their mission statements. Frontiers reserves the right to guide an out-of-scope manuscript to a more suitable section or journal at any stage of peer review.
