Identification of Mustard Aldehyde Dehydrogenase (ALDH) Gene Family and Expression Analysis Under Salt and Drought Stress.

ABSTRACT:

Background/objectives

Abiotic stresses severely constrain the yield of Brassica juncea, and aldehyde dehydrogenases (ALDHs) play a pivotal role in plant stress resistance. This study aims to systematically identify the ALDH gene family members in B. juncea and elucidate their expression patterns under salt and drought stress.

Methods

Using the Arabidopsis thaliana AtALDH proteins as seed sequences, BLASTp alignment was performed against the B. juncea whole-protein sequence database, combined with the conserved domain PF00171 of the ALDH proteins. A total of 39 BjALDH gene family members were identified, and their physicochemical properties, structures, phylogenetic relationships, interspecies collinearity, and intraspecies collinearity were
