Identification, Classification and Characterization of bZIP Transcription Factor Family Members in Pinus massoniana Lamb.

Basic leucine zipper (bZIP) transcription factors (TFs) are ubiquitous in eukaryotes. Members of this family play significant roles the regulation plant growth, signal transduction, and various stresses. To date, bZIP TFs have been extensively studied plants, but there is little information about them Pinus massoniana Lamb. In study, 55 were identified based on data from four different P. transcriptomes, a systematic analysis was performed. According to phylogenetic results, divided into 11 groups. Each protein contained highly conserved domain, numbers types motifs similar same group. The PmbZIPs nuclear localization proteins. Based pine wood nematode inoculation transcriptome, transcriptional profiles revealed that 25 PmbZIP genes could respond nematodes at levels. Genes PmbZIP3, PmbZIP4, PmbZIP8, PmbZIP20, PmbZIP23 selected be upregulated process with nematodes. These five had expression levels tissues responsive related treatment conditions. Transcriptional activity showed PmbZIP3 PmbZIP8 activators; PmbZIP20 repressors. findings provide preliminary TFs, which helpful for further study other physiological functions massoniana.
