The A-type response regulator ARR4 is an element in the two-component signalling network of Arabidopsis. ARR4 interacts with the N-terminus of the red/far-red light photoreceptor phytochrome B (phyB) and functions as a modulator of photomorphogenesis. In concert with other A-type response regulators, ARR4 also participates in the modulation of the cytokinin response pathway. Here evidence is presented that ARR4 directly modulates the activity state of phyB in planta, not only under inductive… CONTINUE READING
