BZIP24 | Basic leucine zipper 24; Transcription factor involved in the regulation of salt stress response. Functions as a negative transcriptional regulator of salt stress acclimation response by regulating cation homeostasis. Regulates negatively the expression of genes contributing to ion and osmotic homeostasis during salt stress, such as the Na(+) transporter HKT1, the Na(+)/H(+) antiporter SOS1, the aquaporin PIP2-1 and the glutamine synthetase GLN1-3. In addition, targets genes with functions in plant growth and development, such as argonaute 4 (AGO4) and cyclophilin 19 (CYP19). (227 aa) | ||||
BZIP19 | Basic leucine zipper 19; Transcription factor involved in the response to zinc ion deficiency. Binds to the consensus sequence 5'-[AG]TGTCGACA[CT]-3' also called zinc deficiency response element (ZDRE). The ZDRE sequence is conserved in the plant kingdom and present in the promoters of genes that constitute the primary response to zinc deficiency, comprising additional ZIP metal transporter genes. Required for zinc accumulation in roots. Mediates the expression of the zinc transporters ZIP3, ZIP4, ZIP5 and ZIP9 during growth in zinc-deficient conditions. ZIP9 transporter is involved in [...] (261 aa) | ||||

The ZDRE sequence is conserved in the plant kingdom and present in the promoters of genes that constitute the primary response to zinc deficiency, comprising additional ZIP metal transporter genes. Required for zinc accumulation in roots. Mediates the expression of the zinc transporter ZIP12 during growth in zinc- deficient conditions. ZIP12 transporter is involved in zinc uptake in roots.
