Oryza sativa subsp. indica ARR-B Family


Tajima et al. 2004: In Arabidopsis thaliana, a Histidine-to-Aspartate (His-->Asp) phosphorelay is involved in the signal transduction for propagation of certain stimuli, such as plant hormones. Through the phosphorelay, the type-B phospho-accepting response regulator (ARR) family members serve as DNA-binding transcriptional regulators, whose activities are most likely regulated by phosphorylation/dephosphorylation.
