Abstract:
The bZIP family members belong to an important kind of transcriptors, which regulate plant growth and development, and responses to biotic and abiotic stresses in plants. Based on systematic bioinformatics methods in this study, 79 bZIP genes were identified in Actinidia chinensis. The absence of bZIP members in Group J, K and L was revealed by phylogenetic analyses. Among kiwifruit bZIP family members, the bZIP domains consist of a basic region and a leucine zipper. There were some variants in the leucine residues of 7 th position in the fourth and fifth peptide of leucine zipper region. Besides bZIP domains, another 8 kinds domains, including bZIP_C, were identified in 18 kiwifruit bZIP family members, which were distributed in Group A, C, D and G. The comparisons of bZIP homologous genes between kiwifruit, grapevine and tomato demonstrated the bZIP genes’ members expansions in kiwifruit mainly resulted from the genome triplication. The RNA-Seq data of kiwifruit fruits from different developmental stages represented the expression profiles of 57 bZIP genes, which might regulate the fruit ripening. Our studies demonstrated the evolution characteristics, domain compositions and the reasons of family members expansions of kiwifruit bZIP family members, and could provide good gene candidates for future studies of fruit ripening in A. chinensis.
