Annotated Information

Gene Symbol

• Os11g0218000 <=> OsbZIP82,OsbZIP, bZIP82

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.
