Comprehensive analysis of cinnamoyl-CoA reductase (CCR) gene family in wheat: implications for lignin biosynthesis and stress responses.

ABSTRACT:

Background

Lignin, the second most abundant terrestrial biopolymer, represents a significant renewable natural biomaterial. Cinnamoyl-CoA reductase (CCR) catalyzes the conversion of various hydroxycinnamoyl-CoA esters into their corresponding aldehydes, utilizing NADPH as a cofactor. CCR functions as a regulatory point that controls the overall carbon flux towards lignin and constitutes the initial committed step in the lignin biosynthesis pathway. Additionally, CCR plays a crucial role in plant development and in resistance to biotic and abiotic stresses. Bread wheat (Triticum aestivum L.), a hexaploid crop, serves as a staple food for much of the global population. However, the copy number variation and expression characteristics of wheat CCR genes remain to be elucidated.
