Divergence of functions and expression patterns of soybean bZIP transcription factors.

ABSTRACT: Soybean (Glycine max) is a major protein and oil crop. Soybean basic region/leucine zipper (bZIP) transcription factors are involved in many regulatory pathways, including yield, stress responses, environmental signaling, and carbon-nitrogen balance. Here, we discuss the members of the soybean bZIP family and their classification: 161 members have been identified and clustered into 13 groups. Our review of the transcriptional regulation and functions of soybean bZIP members provides important information for future study of bZIP transcription factors and genetic resources for soybean breeding.

Project description:BackgroundChenopodium quinoa Willd. (quinoa) is a pseudocereal crop of the Amaranthaceae family and represents a promising species with the nutritional content and high tolerance to stressful environments, such as soils affected by high salinity. The basic leucine zipper (bZIP) transcription factor represents exclusively in eukaryotes and can be related to many biological processes. So far, the genomes of quinoa and 3 other Amaranthaceae crops (Spinacia oleracea, Beta vulgaris, and Amaranthus hypochondriacus) have been fully sequenced. However, information about the bZIPs in these Amaranthaceae species is limited, and genome-wide analysis of the bZIP family is lacking in quinoa.ResultsWe identified 94 bZIPs in quinoa (named as CqbZIP1-CqbZIP94). All the CqbZIPs were phylogenetically splitted into 12 distinct subfamilies. The proportion of CqbZIPs was different in each subfamily, and members within the same subgroup shared conserved exon-intron structures and protein motifs. Besides, 32 duplicated CqbZIP gene pairs were investigated, and the duplicated CqbZIPs had mainly undergone purifying selection pressure, which suggested that the functions of the duplicated CqbZIPs might not diverge much. Moreover, we identified the bZIP members in 3 other Amaranthaceae species, and 41, 32, and 16 orthologous gene pairs were identified between quinoa and S. oleracea, B. vulgaris, and A. hypochondriacus, respectively. Among them, most were a single copy being present in S. oleracea, B. vulgaris, and A. hypochondriacus, and two copies being present in allotetraploid quinoa. The function divergence within the bZIP orthologous genes might be limited. Additionally, 11 selected CqbZIPs had specific spatial expression patterns, and 6 of 11 CqbZIPs were up-regulated in response to salt stress. Among the selected CqbZIPs, 3 of 4 duplicated gene pairs shared similar expression patterns, suggesting that these duplicated genes might retain some essential functions during subsequent evolution.ConclusionsThe present study provided the first systematic analysis for the phylogenetic classification, motif and gene structure, expansion pattern, and expression profile of the bZIP family in quinoa. Our results would lay an important foundation for functional and evolutionary analysis of CqbZIPs, and provide promising candidate genes for further investigation in tissue specificity and their functional involvement in quinoa's resistance to salt stress.
