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.

🌿🟢 REVIEW 🟢🌿 This review focuses on recent advances in chloroplast biogenesis and chromoplast differentiation, with emphasis on transcriptional regulation, and identifies areas where further progress is needed – Hernández-Verdeja 🔗 doi.org/10.1093/jxb/... #PlantScience 🧪
Fig. 1 (shortened, full legend in paper): Nuclear transcriptional regulation of chloroplast biogenesis. Chloroplast development in cotyledons of land plants during the transition from seedlings germinating in the dark (etiolated) to green seedlings in the light. Plastids are inherited as proplastids in seeds. In etiolated cotyledons, proplastids differentiate into etioplasts, characterized by the prolamellar body (PLB). Perception of light initiates the light developmental programme and chloroplast development. The PLB starts to disaggregate, thylakoid membranes (tm) start to form, and chlorophyll accumulates. Transcription of nuclear genes involved in chloroplast development is actively inhibited in the dark by PIFs and their interaction with other proteins, such as EIN3 and BZR1. Light signalling pathways target PIFs and EIN3 for degradation, lifting the repression, and allow transcription and activity of several TFs, leading to massive transcriptional changes.

Integrating ‘cry for help’ strategies for sustainable agriculture
Plants recruit specific soil microbes through a sophisticated ‘cry for help’ strategy to mitigate environmental stresses. Recent advances highlight the potential of leveraging this mechanism to develop microbe-based approaches for enhancing crop health, but challenges remain in refining the criteria and conceptual frameworks to effectively investigate and harness these plant–microbe interactions.
