| Abstract: | Background Soybean, a major legume crop native to East Asia, presents a wealth of resources for utilization. The basic leucine zipper (bZIP) transcription factors play important roles in various biological processes including developmental regulation and responses to environmental stress stimuli. Currently, little information is available regarding the bZIP family in the legume crop soybean. Results Using a genome-wide domain analysis, we identified 160GmbZIPgenes in soybean genome, named fromGmbZIP1toGmbZIP160. These 160GmbZIPgenes, distributed unevenly across 20 chromosomes, were grouped into 12 subfamilies based on phylogenetic analysis. Gene structure and conserved motif analyses showed thatGmbZIPwithin the same subfamily shared similar intron-exon organizations and motif composition. Syntenic and phylogenetic analyses identified 40Arabidopsis bZIPgenes and 83 soybeanbZIPgenes as orthologs. By investigating the expression profiling ofGmbZIPin different tissues and under drought and flooding stresses, we showed that a majority ofGmbZIP(83.44%) exhibited transcript abundance in all examined tissues and 75.6% displayed transcript changes after drought and flooding treatment, suggesting thatGmbZIPmay play a broad role in soybean development and response to water stress. Conclusions One hundred sixtyGmbZIPgenes were identified in soybean genome. Our results provide insights for the evolutionary history of bZIP family in soybean and shed light on future studies on the function ofbZIPgenes in response to water stress in soybean. |
