Arabidopsis Produces Distinct Subpopulations of Extracellular Vesicles That Respond Differentially to Biotic Stress, Altering Growth and Infectivity of a Fungal Pathogen Extracellular vesicles (EVs) secreted by mammalian cells are highly heterogeneous in content and function. Whether this is also true for EVs secreted by plant cells is not yet known. To address this,...

Our latest analysis of plant EVs led by Ben Koch with the help of Brian Rutter, @luciaborniego.bsky.social‬, @msr20.bsky.social‬, and Dillon Gardner is now available open access. LOTS of new data added to our previous bioRxiv posting. Check it out isevjournals.onlinelibrary.wiley.com/doi/10.1002/...

I am so happy and so honored to be part of this year’s class of plant biologists elected to the NAS! Huge thanks to all my past and current students and postdocs that made this possible.

Abundant, unusual RNAs on the leaf surface | Plantae It seems that there is no end to the surprises that RNA provides. To the old-school trio of mRNA, tRNA, and rRNA, the past 20 years have added miRNA, siRNA, tasiRNA and others, all with unique and…

Diverse plant RNAs coat Arabidopsis leaves and are distinct from apoplastic RNAs | PNAS Transgenic expression of a double-stranded RNA in plants can induce silencing of homologous mRNAs in fungal pathogens. Although such host-induced g...

What a great start to the year 2025. Just published online is our PNAS paper - Diverse plant RNAs coat Arabidopsis leaves and are distinct from apoplastic RNAs www.pnas.org/doi/10.1073/...

Protocol for isolating RNA from the surfaces and apoplastic spaces of plant leaves.

Very happy to start the new year with publication of our new work on leaf surface RNA. Plant leaves secrete diverse RNAs that are surprisingly stable on their surfaces. Next question to answer: What do they do? www.pnas.org/doi/epub/10....

Thanks Cris!

Suchi Ghosh, Ben Koch, and Allie Margets, freshly hooded, in their Ph.D. graduation robes.

Proud mentor of Ph.D. triplets! Congratulations to Suchismita Ghosh, Ben Koch, and Alexandra Margets! All have a great future in front of them. It's been a great six years in the Innes Lab.

A common immune response node in diverse plants Small molecules activate a defense mechanism shared by all flowering plants

Great to be able to comment with Jeff Dangl on a couple of important papers published today in Science www.science.org/doi/10.1126/...

Interfamily co-transfer of sensor and helper NLRs extends immune receptor functionality between angiosperms Plant nucleotide-binding, leucine-rich repeat (NLR) immune receptors recognize pathogen effectors and activate defense. NLR genes can be non-functional in distantly related plants (restricted taxonomi...
