Excited to share our latest work on plant immune receptor biochemistry! @kamounlab.bsky.social @hsuanpai.bsky.social @mpcontreras.bsky.social Jose Salguero Linares @danielluedke.bsky.social @adnroide.bsky.social @jiorgoskourelis.bsky.social

CC-NLRs exhibit diverse conformations in the resting state. Figure depicts different NLR resting and activated states. While ZAR1 exists as a monomer bound to its guardees in its resting state, several forms have been observed for the NRC2 helper, including dimers, tetramers, and filaments. While filament-like structures were observed via confocal microscopy for NRC2 upon overexpression in planta, these structures were not detected for its paralog NRC4, suggesting a potentially different resting state configuration for NRC4. Our work suggests that the Pik CC-NLR pair forms a hetero-complex bound to the plasma membrane in its resting state. How effector binding to the integrated domain (ID) of the Pik-1 sensor leads to the activation of the complex remains to be determined.

I just published: On the diversity of resting states of NLR immune receptors

New story on rice Pik NLR immune receptor pair — turns out it sits as a 1 MDa membrane-bound beast before activation 🤯. Another wild twist in the ever-expanding universe of NLR resting states!

How can we better understand the plant immune system? In my new @cp-cellhostmicrobe.bsky.social piece, I propose “immune cell states” as a framework for uniting molecular and cellular perspectives.

An important consequence of the analysis by Paajanen et al is that the 'cell-to-cell mobile RNA' user-defined description listed under Gene Ontology by TAIR is a classification based on flawed analyses. Be careful!

Interesting - bik1 T-DNA mutants are smaller, have high levels of SA (autoimmune phenotype), but CRISPR mutants do not have more severe compromised defense.
