Annotated Information

Gene Symbol

  • Os03g0127500 <=> OsbZIP025,OsbZIP, bZIP025

Function

  • The basic leucine (Leu) zipper (bZIP) proteins compose a family of transcriptional regulators present exclusively in eukaryotes.
  • The OsbZIP proteins characteristically harbor a bZIP domain composed of two structural features: a DNA-binding basic region and the Leu zipper dimerization region.
  • bZIP proteins have been shown to regulate diverse plant-specific phenomena, including seed maturation and germination, floral induction and development, and photomorphogenesis, and are also involved in stress and hormone signaling.

Expression

  • The researchers from India find specific or coexpression patterns of rice bZIP transcription factors starting from floral transition to various stages of panicle and seed development.
  • bZIP transcription factor-encoding genes in rice also displayed differential expression patterns in rice seedlings in response to abiotic stress and light irradiation.

Evolution

  • The phylogenetic relationship among rice bZIP domains as well as with bZIP domains from other plant bZIP factors suggests that homologous bZIP domains exist in plants.
  • Similar intron/exon structural patterns were observed in the basic and hinge regions of their bZIP domains.
  • Detailed sequence analysis has been done to identify additional conserved motifs outside the bZIP domain and to predict their DNA-binding site specificity as well as dimerization properties, which has helped classify them into different groups and subfamilies, respectively.
