Genome-wide identification of chitinase gene family in Hordeum vulgare: insights into stress response mechanisms and evolutionary dynamics.

ABSTRACT:

Background

Chitinase, a key enzyme family within the pathogenesis-related (PR) protein, plays a crucial role in plant defense by degrading chitin, a major component of fungal cell walls. The HvCHT genes in barley are involved in responses to biotic and abiotic stresses, although their full range of functions is not yet fully understood.

Results

In this study, we identified 24 potential HvCHT genes through a genome-wide analysis. The comparative synteny analysis showed conserved relationships between HvCHT genes and their homologs in Sorghum bicolor, Oryza sativa, and Arabidopsis thaliana. Chromosomal mapping, gene structure, characterization, protein motif analysis, and miRNA regulation were performed to gain insight into the genetic structures of these genes. Segmental dupl
