Very happy to share our new paper in Plant Physiology! 🌽 We uncover a 2-step mechanism controlling maize phytocytokine Zip1: ZmMC9 processes PROZIP1 intracellularly, enabling export of bioactive Ct-PROZIP1, while apoplastic proteases attenuate the signal. doi.org/10.1093/plph...
Schematic model of the two-step processing and regulation of the maize phytocytokine PROZIP1/Zip1. Intracellularly, PROZIP1 associates with the ER and is cleaved by the Ca²⁺-dependent type II metacaspase ZmMC9, generating the C-terminal fragment Ct-PROZIP1. This bioactive fragment is exported to the apoplast through a Golgi-independent route, where it activates immune signaling. In a second step, apoplastic proteases, including the papain-like cysteine proteases CP1 and CP2, further process and degrade Ct-PROZIP1 and Zip1, thereby attenuating and clearing the signal.
