New pre-print from the team!

The manuscript is @emma-raven.bsky.social's PhD work showing that whether a leaf is a carbon sink or a carbon source influences how they execute immune responses.

Have a read!

🚨 New paper alert!

Our work is published in PNAS! @junli-wang.bsky.social @mpipz.bsky.social

In this study, we uncover how NLR-assembled and canonical Ca2+ ion channels cooperate to confer robust resistance against disease in plants.

Check it out here: www.pnas.org/doi/10.1073/...

📣 NEW PREPRINT 📝

We identified evolutionary origins of many fungal effectors!
We show that fungi secrete lots of antimicrobial proteins, and that some of them were repurposed by plant pathogens for host immune suppression.

Plant-associated fungi co-opt ancient antimicrobials for host manipulation
Evolutionary histories of effector proteins secreted by fungal pathogens to mediate plant colonization remain largely elusive. While most functionally characterized effectors modulate plant immunity, ...
