Unwinding JAZ7 – enigma to harmony

JASMONATE ZIM-DOMAIN (JAZ) proteins are primary transcriptional repressors in the jasmonate (JA) signaling pathway that regulate a broad range of JA-dependent responses. A mechanistic mode of action is well established, but what are the biological roles of individual JAZs, and how do they contribute to the specification of JA signaling outputs? Two recent articles in Journal of Experimental Botany reveal roles of JAZ7 in regulating dark-induced senescence and susceptibility to fungal pathogens.
