Identification and expression analysis of bZIP transcription factors in in response to dehydration stress.

Among the largest transcription factor families in plants, bZIPs are crucial for various developmental and physiological processes, particularly abiotic stress resistance. has become a model for understanding stress resistance mechanisms. In this study, we identified 90 bZIP transcription factors in the genome. were classified into 13 groups based on references to bZIPs. Members in the same group shared similar motifs and gene structure pattern. In addition, gene duplication analysis indenfied 37 pairs of segmental duplicated genes and none tandem duplicated genes in suggesting segmental duplication contributed to the expansion of the bZIP gene family. Moreover, the number of genes (39) exhibiting higher expression in roots was significantly more than that in other organs. Twelve genes were upregulated in response to dehydration stress. In conclusion, our study advances the current understanding of genes and provide a number of candidates for functional analysis of drought tolerance in .
