In the absence of gibberellin, the DELLA proteins positively regulate GID1, GA20ox, and GA3ox (plus signs), and negatively regulate GA2ox (minus sign). Conversely, both bioactive gibberellin and the GID1 receptor enhance DELLA repressor degradation (plus signs), while GA2ox blocks DELLA repressor degradation (minus signs).
