Key message DELLA proteins’ negative regulation of dark-induced senescence and chlorophyll degradation in Arabidopsis is through interaction with WRKY6 and thus repression of its transcriptional activities on senescence-related genes. Abstract Senescence is an intricate and highly orchestrated process regulated by numerous endogenous and environmental signals. Gibberellins (GAs) and their signaling...
Key message DELLA proteins positively regulate nitrogen deficiency-induced anthocyanin accumulation through directly interaction with PAP1 to enhance its transcriptional activity on anthocyanin biosynthetic gene expressions. Abstract Plants can survive a limiting nitrogen supply by undergoing adaptive responses, including induction of anthocyanin production. However, the detailed mechanism is still...
