Genome-wide Identification of bZIP Gene Family in Potato and Their Ex-pression Analysis under Different Stress
Basic leucine zipper(bZIP)is a conserved transcription factor widely existing in plants.Its family mem-bers are one of the most abundant transcription factor families in plants.In order to understand the related informa-tion of potato StbZIP gene family,64 members of potato StbZIP family were identified in the whole genome of diploid potato'DM'by bioinformatics method,and named StbZIP1～StbZIP64.The results showed that the StbZIP gene were unevenly distributed on 12 chromosomes.The length of StbZIP family members was between 132 to 822 aa,the molecular weight was between 15.40 to 88.18 kD,and the isoelectric point was between 4.74 to 10.30.Phylogenetic tree analysis showed that the StbZIP genes were divided into 11 subfamilies,and its genes were main-ly distributed on chromosome 1,4 and 10.Analysis of gene structure and conserved motifs showed that members of each subfamily had similar conserved motifs and evolutionary conserved nature.Analysis of expression patterns revealed that 11 subgroups showed expression patterns in response to different abiotic stresses.Among them,8 subgroup genes showed a significant increase in expression levels at 24 h of ABA stress.These findings provide useful information to elucidate the StbZIP gene family's evolutionary relationship and to further analyze the func-tional characteristics of the StbZIP gene.
