The DELLA proteins GAI, RGA, RGL1 and RGL2 in Arabidopsis are plant growth repressors, repressing diverse developmental processes. Studies have shown that gibberellin (GA) attenuates the repressive function of DELLA proteins by triggering their degradation via the proteasome pathway. However, it is not known if GA-induced protein degradation is the only pathway for regulating the bioactivity of DELLA proteins. We show here that tobacco BY2 cells represent a suitable system for studying GA… CONTINUE READING
