Suberin Polyester Barrier in Plants: Biosynthesis and Its Regulation

초록

Suberin is a specialized biopolymer that forms hydrophobic barriers between the plasma membrane and the cell wall, playing a crucial role in regulating water and solute transport, as well as protecting plants from both biotic and abiotic stresses. This review highlights recent advances in genetic and biochemical studies that have led to the identification of key genes involved in suberin biosynthesis, transport, polymerization, and its regulatory mechanisms. These findings are not limited to the model plant Arabidopsis, but also apply to various crop and woody species. A deeper understanding of the developmental and environmental regulation of suberin biosynthesis and deposition provides noble strategies for enhancing barrier properties and developing climate-resilient crops.
