🎙️Season 2 of our podcast is here! Kicking things off with the mind-blowing study below.
This research shatters the assumption that herbarium specimens are unsuitable for transcriptomics, successfully extracting mRNA from historical plant samples:

Getting quality transcriptome assemblies from Herbarium samples is possible doi.org/10.1101/2025.... Work led by @atyszka.org. Another fun collaboration with @philcarella.bsky.social and @khongsamchia.bsky.social, who functionally validated an NLR immune receptor from a sample collected in 1956.
Herbaria provide a valuable resource for obtaining informative mRNA
While DNA has built the framework for molecular insights from museum collections, the utility of archival RNA remains largely unexplored. Likely a consequence of the known instability of RNA relative ...

RNA from herbarium specimens is more stable than you think. Cool new study from @atyszka.org @evojfwalker.bsky.social and team. @khongsamchia.bsky.social and I were happy to contribute by functionally validating an NLR immune receptor last expressed in 1956 : www.biorxiv.org/content/10.1...

Don’t fall into the trap of normalizing any of this with this sort of language that we’ve seen from so many universities, falsely equating the current situation with other presidential transitions
This is unprecedented, unconscionable, and deliberately disruptive.
Have the backbone to say that.

Happy year of the snake! I would argue that the snakes of the United States are just as varied and pretty as our birds. A few years ago I made a poster to try and prove it. Drawing this took many months and a lot of research. You can get it here:

Hello! This is my intro post (and a well-timed reminder to myself to get working on conference presentations for the year). I am finally making the long-overdue move from twitter. Here are two papers I've been a part of recently!

Very happy to share the final version of our work on the evolution of broad host virulence in Pseudomonas out now @cellhostmicrobe It’s just in time for the holidays 🎄🦠 www.cell.com/cell-host-mi...
A necrotizing toxin enables Pseudomonas syringae infection across evolutionarily divergent plants
Grenz et al. interrogate the Pseudomonas syringae species complex for its capacity to infect evolutionarily divergent host plants. Their results demonstrate that broad host isolates from phylogroup 2 rely on the lipopeptide toxin syringomycin to promote host necrosis and enhance bacterial growth in plants.
