Brief Introduction
- bZIP transcription factors are named according to their bZIP domain, which is composed of a basic region and a Leu zipper[1][2][3]. The basic region consists of about 16 to 18 amino acid residues characterized with an invariant N-x7-R/K motif whereas the Leu zipper is composed of heptad repeats of Leu or other bulky hydrophobic amino acids (Ile, Val, Phe, or Met) positioned exactly nine amino acids toward the C terminus[1][2].
- Plant bZIP transcription factors participate in the differentiation of many organs and tissues, embryogenesis, seed maturation, floral transition and initiation, and vascular development[1][2][3][4]. bZIP transcription factors are also involved in signalling and responses to abiotic/biotic stimuli, including ABA signalling, osmotic, hypoxia, drought, high salinity and cold stresses, and pathogen defence[2][3][4]. Some bZIPs also respond to light irradiation and are involved in photomorphism[3].
- The phylogenetic analysis of bZIP proteins in rice made by Aashima Nijhawan et al. showed that bZIP transcription factor genes have appeared before divergence between monocots and dicots. The structure and function of most of the bZIP genes has probably remained conserved during angiosperm evolution[1].
