Citrus greening (aka Huanglongbing or HLB) is a major threat to the citrus industry worldwide. There is much work to be done to curb the effects of this disease, especially in the face of increased climate threats.

Our latest work sheds light on how chloroplasts enhance plant immunity by moving toward and attaching to the plant-pathogen membrane interface. 👇
⚠️Excited to share my latest in @ThePlantCell🌱! We show that chloroplasts form membrane contact sites (MCS) with the pathogen interface to drive focal immunity, mediated by a tethering complex🔗! Full story 👉 https://t.co/LE3SVlxp5i

I'm very happy that this paper is now published in PNAS! Isochorismate-based SA biosynthesis appears to have emerged in the Brassicales after the divergence of C. papaya, likely within the timeframe between the divergence of B. maritima and R. odorata. https://t.co/nHY1cfPHFu

Salicylic acid (SA) is a major defense phytohormone. In Arabidopsis thaliana, the isochorismate (IC) pathway is the primary route for pathogen-indu...

Have you ever wondered how phytocytokines are transported to the extracellular space and which factors regulate this process? We elucidated this mechanism for the maize-specific phytocytokine Zip1. https://t.co/LrxbIa6PTf
