Abstract

A transcription factor RCBF2 which interacts with C-repeat/DRE was isolated from Oryza sativa L. by a yeast one-hybrid method. Analysis of the deduced RCBF2 amino acid sequence revealed that RCBF2 contained a conserved ethylene-responsive element binding protein (EREBP)/AP2 domain of 59 amino acids and a potential nuclear localization sequence. RCBF2 showed a high level of homology with other CBF family members only in AP2 domain. Phylogenetic analysis showed that RCBF2 might be different from other eight DRE-binding proteins on evolutionary relationship. The semi-quantitative RT-PCR (s-Q RT-PCR) analysis indicated the expression of RCBF2 gene was induced by cold, dehydration and high-salinity, but not by abscisic acid, and the transcription of RCBF2 gene accumulated primarily in rice immature seeds, growing point and shoots.
