Nature Plants - The evolutionary diversification of an exocyst subunit was enabled by electrostatic shifts leading to its dissociation from the ancestral complex.
How can protein complexes diversify without compromising their function? In our new pre-print, we explore this question using the plant #exocyst 🧵 https://t.co/WrRCZR9HsJ

4\ We found a class of immune receptors enriched in ferns. They could be CC-NLRs, or potentially a new class of intracellular immune receptors. They remain to be characterized … (drop us a message if you are interested in doing that with us ⬇️) 4/4

3\ Ferns reproduce via alternance of gametophytes (💚 algae-looking tiny plants) and sporophyte (🌿dominant phase, the form we are most familiar with). For some pathogens, gametophytes are more resistant than their sporophyte. 3/4

The success of plants on land has been enabled by mutualistic intracellular associations with microbes for 450 million years ([Delaux and Schornack 2021][1]). Because of their intracellular nature,...

The literature on domestication commonly calls the association between human domesticators and their plant and animal domesticates mutualistic, yet this designation is rarely examined critically....

We bid farewell to Mauricio Contreras @mpcontreras4, who contributed so much to @TheSainsburyLab — not only through his outstanding science but also by fostering an open, collaborative, and supportive culture among students and postdocs. We’ll miss him!
It’s essentialy a week of festivities to bid San Mau @mpcontreras4 farewell after 7+ incredible amazing years! Work hard, play hard…

⚠️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

Chloroplast tethering to the pathogen interface via membrane contact sites promotes focal callose deposition and strengthens plant immunity.

How can we better understand the plant immune system? In my new @cellhostmicrobe piece, I propose “immune cell states” as a framework for uniting molecular and cellular perspectives. https://t.co/Sqs729IzkH

A new preprint involving the labs of @jonathandgjones and @kamounlab unveils the structure of the largest plant resistosome to date. The octameric WAI3 resistosome was found in wheat, but similar arrangements are found in other plants 🌾 Check it out 👉 https://t.co/Vvxo4yoFce

Congratulations He, impressive work
Wheat never fails to surprise us—like a CNL that assembles just like a TNL!
