| Summary: | [Objective] Suberin is a polyester type biopolymer that specifically deposits in tissues such as the
endodermis, periderm, seed coat, and wound epidermis of plants. Acting as a barrier between the plants
and their environment, suberin controls the transport of water and solutes, protecting plants from environmental
stresses and pathogenic invasion. This article reviews the key enzymes and transcription factors
involved in suberin biosynthesis, and discusses the impact of environmental factors on suberin synthesis
and deposition. The future research direction was prospected. [Reviews] The regulation of suberin involves
various factors, including key enzymes such as β-ketoacyl-CoA synthase (KCS), fatty acyl reductase
(FAR), cytochrome P450 enzymes (CYP family), and transcription factors such as MYB, NAC,
WRKY. Environmental factors also regulate the biosynthesis and deposition of suberin through complex
signal transduction pathways. [Prospect] Future research should focus on the key regulatory nodes of suberin
biosynthesis, particularly exploring the factors that influence species-specific deposition of suberin in
crops. By leveraging multi-omics approaches to elucidate its transport, assembly, and post-transcriptional
regulation mechanisms, there is potential to provide new strategies for enhancing nutrient use efficiency
and stress resistance in crop genetic improvement. |
