Genome-wide evolutionary characterization and analysis of bZIP transcription factors and their expression profiles in response to multiple abiotic stresses in Brachypodium distachyon.

ABSTRACT:

Background

Plant basic leucine zipper (bZIP) transcription factors are one of the largest and most diverse gene families and play key roles in regulating diverse stress processes. Brachypodium distachyon is emerging as a widely recognized model plant for the temperate grass family and the herbaceous energy crops, however there is no comprehensive analysis of bZIPs in B. distachyon, especially those involved in stress tolerances.

Results

In this study, 96 bZIP genes (BdbZIPs) were identified distributing unevenly on each chromosome of B. distachyon, and most of them were scattered in the low CpG content regions. Gene duplications were widespread throughout B. distachyon genome. Evolutionary comparisons suggested B. distachyon and rice's bZIPs had the similar evolutionary patt
