MPK6-mediated phosphorylation destabilizes MYC2 and attenuates its transcriptional activity in jasmonate signaling

Given the role of MYC2 as a pivotal regulator in the jasmonate (JA) signaling pathway, influencing the expression of a multitude of downstream genes (Zander et al., 2020), understanding the regulatory dynamics of MYC2 is essential for unraveling plant responses to stress conditions and hormonal signals. Previous studies on the regulation of MYC2 by MPK6 have reported conflicting findings. Takahashi et al. (2007) reported that MPK6 acts as a negative regulator of MYC2, whereas Sethi et al. (2014) proposed a positive regulatory role. Despite these findings, the precise genetic and biochemical mechanisms underlying the MPK6–MYC2 interaction remain poorly understood, highlighting the need for further investigation.
