Genome-wide identification, structural and gene expression analysis of the bZIP transcription factor family in sweet potato wild relative Ipomoea trifida.

ABSTRACT:

Background

The basic leucine zipper (bZIP) transcription factor is one of the most abundant and conserved transcription factor families. In addition to being involved in growth and development, bZIP transcription factors also play an important role in plant adaption to abiotic stresses.

Results

A total of 41 bZIP genes that encode 66 proteins were identified in Ipomoea trifida. They were distributed on 14 chromosomes of Ipomoea trifida. Segmental and tandem duplication analysis showed that segmental duplication played an important role in the ItfbZIP gene amplification. ItfbZIPs were divided into ten groups (A, B, C, D, E, F, G, H, I and S groups) according to their phylogenetic relationships with Solanum lycopersicum and Arabidopsis thaliana. The regularity of the exon/intr
