Abstract:

Plant secondary cell walls (SCWs) contain cellulose, hemicellulose and lignin, which endow the cell walls with mechanical strength and hydrophobicity. This characteristic is very important for plant upright growth, water and nutrient transport, and resistance to biotic and abiotic stresses. In this review, we summarize the transcription factors regulating SCW biosynthesis and their regulatory mechanisms, including NAC transcription factors functioning as first-layer master switch, the AtMYB46/AtMYB83 and their downstream regulators serving as secondary-layer master switch, as well as the other transcription factors involved in the regulation of biosynthesis of the SCW. The future research contents and methods are also prospected in order to provide reference for further research on the transcriptional regulatory network of SCW biosynthesis.
