Abstract Plants are easily exposed to a wide range of adverse environmental conditions. Lipids, as one of the most crucial components of biological membranes in all plant tissues, have stoked great attention recently, especially in response to stresses. It has been shown that membrane lipid remodeling is one of the effective adaptation strategies for plants to defense against various abiotic stresses, including drought, salt, chilling, heat, nutrient deficiency and heavy mental stresses etc. Characterizing the response of membrane lipids to different abiotic stresses becomes crucial for improving plant acclimatization ability to different environmental adversities. The present review gives the holistic alteration of plant lipid in response to a series of abiotic stresses based on the meta-analysis. The possible underlying mechanisms of membrane lipid remodeling in mediating abiotic stress tolerance, and the role of lipids or its’ intermediates as signaling molecules under abiotic stresses are discussed.
