Excited and honored to attend #PAG33 as an invited speaker! I’ll be sharing our work on maize leaf surface RNAs and asking how tRFs and rRFs may shape plant–microbe interactions. Looking forward to connecting and exchanging ideas !!

Have you ever wondered how we isolated the RNAs coating Arabidopsis leaf surfaces?

Our new JoVE paper shows the step-by-step protocol + video for isolating leaf surface & apoplastic RNAs!

Spotted myself and Dr. Roger Innes in the promo for #PlantBio2026 — and it genuinely made me smile.

Feeling thankful to be part of a global community that brings plant scientists together to share, learn, and grow.

Did you know there are various types of RNAs on leaf surfaces of corn plants grown in the field? The host RNAs are secreted on the leaf surface and they coexist with the microbiome. @rnasociety.bsky.social #RNA30 #RNA #exRNA

Excited to attend the 30th RNA biology conference, San Diego. As a plant biologist it would be interesting to learn about new technologies in the RNA world and also share our work on maize extracellular RNAs #RNASociety @rnasociety.bsky.social #exRNA

Congratulations Dr. Jones 💐💐

RNA-binding proteins and glycoRNAs form domains on the cell surface for cell-penetrating peptide entry Mammalian cells present RNA-binding proteins on the cell surface that form clustered domains containing glycoRNAs.

What an outstanding study! This majorly expands our understanding by showing that glycosylated RBPs are not only present but also organized into specialized clusters. New avenues for cellular communication and therapeutic delivery strategies! Many congratulations @raflynn5.bsky.social and team.

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....

A type II secreted subtilase from commensal rhizobacteria cleaves immune elicitor peptides and suppresses flg22-induced immune activation Eastman, Jiang, and Ficco et al. screen 165 root-associated bacteria for suppression of plant immune activation and growth restriction induced by the peptide immune elicitor flg22. They show that Dyella japonica uses the type II secreted subtilase IssA to cleave the peptide immune elicitors flg22 and AtPEP1 and suppress plant immune activation.
