Abstract
Modulation of membrane lipid composition under varying environmental conditions is an important part of plant stress adaptation. Most notably, proportional changes of lipid composition in response to temperature changes are a major cellular response to requirements of membrane fluidity adjustment. In higher plants, synthesis of glycerolipids is accomplished by 2 major pathways, the prokaryotic and eukaryotic pathway, located in the chloroplast and the endoplasmic reticulum (ER), respectively. Recently, we systematically investigated the re-adjustments of glycerolipid pathways under temperature stress at the metabolite and transcript levels using 3 plant species with distinct lipid profiles. The relative contributions of 2 pathways and lipid channeling from the ER and chloroplast were both observed in plants under temperature stress. Potential factors controlling the lipid flux were identified through transcriptome analysis.
