Genome-wide analysis of CHYR gene family and BnA03.CHYR.1 functional verification under salt stress in Brassica napus L.

ABSTRACT: Brassica napus, an allotetraploid used as an oilseed crop, vegetable, or feed crop, possesses significant economic and medicinal value. Although the CHYR gene family has been functionally characterised in various aspects of plant growth, development, and stress responses, its systematic investigation in B. napus is lacking. In contrast to the seven CHYR genes (AtCHYR1-AtCHYR7) identified in Arabidopsis thaliana, nine CHYR orthologues were detected in B. rapa and B. oleracea, while 24 were found in B. napus. This discrepancy is consistent with the established triplication events that occurred during the Brassicaceae family evolution. Phylogenetic analysis indicated that the 24 CHYRs identified in B. napus could be categorised into three distinct groups. Among these, 24 BnCHYRs contained con
