Abstract

In response to environmental changes, plant roots undergo two major differentiations: the formation of the Casparian strip and the suberin lamella, both of them are widely recognized as an apoplastic diffusion barrier for nutrient and water exchange between the soil and the root vascular bundle. Suberin is a complex biopolyester composed of glycerol esters and phenolic compounds deposited in the cell walls of specific tissues such as endodermis, exodermis, periderm, seed coat and other marginal tissues. Recently, significant progress has been made due to the development of biochemical and genetic techniques. In this review, we not only summarize the aspect of suberin biosynthesis, transport and polymerization, but also elucidate the molecular mechanisms regarding its regulatory network, as well as its adaptive role in abiotic or biotic stress. This will provide important theoretical references for improving crop growth by modifying their adaptive root suberin structure when exposed to environmental changes.

Keywords: Abiotic/biotic stress; biosynthesis; export; phytohormone signal; polymerization; suberin; transcriptional regulation.
