Phospholipids in plant systems: metabolism, regulation and functional insights.

Plant Signaling
Every time you water a wilting tomato or move a houseplant out of the cold, phospholipids are the molecules inside each cell scrambling to keep membranes intact and send the 'we're stressed, adapt now' signal.
Every plant cell is wrapped in a thin skin made partly of molecules called phospholipids. Plants can adjust the mix of these molecules to survive heat, cold, or drought—almost like tuning a thermostat at the cellular level. This review pulls together years of research to explain exactly how plants make, break down, and regulate these molecules, and why getting that balance right is essential for healthy growth.
Key Findings
Phospholipid metabolism is regulated at three distinct levels—transcriptional, post-transcriptional, and post-translational—allowing plants to fine-tune responses rapidly to environmental stress.
Phospholipid pathways are interconnected with glycolipid production and lipid droplet formation, meaning changes in one pathway ripple across multiple cellular processes.
Key enzymes in phospholipid assembly and degradation serve dual roles in both structural membrane maintenance and active stress-signaling, blurring the line between architecture and communication.

Plants carefully manage the fat-like molecules in their cell membranes—called phospholipids—to grow, respond to stress, and send signals. This review maps out how plants build and break down these molecules, and how that balance is controlled at multiple levels.
Abstract Preview
Phospholipids are essential components of cellular membranes in plants and play important roles in several biological processes including membrane biogenesis, signaling, and stress response. Here, ...
