We're hiring! I'm looking for curious, enthusiastic scientists who love neuronal cell biology and are excited about building a new lab together! Postdoc and research technician positions are open. If this sounds like you, I'd love to hear from you! Please share! 💪

Nice!

Heard we should eat 30 different plants a week, so I audited my Saturday: 24–25 plant foods in one day, including a fungal guest appearance by a chanterelle. Coffee counts. Tequila doesn’t. Even a plant biologist has to draw the line somewhere. 🌱🍄

Thanks, wonderful interview:“With plants, since they don't move…we tend to think of them as a backdrop, not as something that's building our world. Yet they're essentially regulating the climate, producing soil fertility, doing all these things without which our lives would be much more complicated”

I’ve just met Sandra Díaz, an influential Argentine biologist, who’s delightful. This interview (in Spanish, but you can easily translate it) where she talks about plants, biodiversity, valuing nature, etc., is worth your time.

To translate these mechanistic insights into crop improvement strategies, future studies should investigate how modulation of OsPSY8 signaling affects plant performance under soil-grown conditions, including greenhouse and field environments.

Such investigations will be essential to determine whether engineering the OsPSY8 pathway can improve drought resilience while maintaining crop productivity under agronomically relevant conditions. Congratulations Yejin!

Yejin made knockouts in rice PSY8 and found that two independent mutants displayed enhanced tolerance to osmotic stress. Survival rates exceeded 60% in both KO1 and KO2, compared with approximately 40% in WT plants

Yejin then showed that OsPSY8 is directly repressed by OsWRKY24, a transcription factor previously shown to positively regulate resistance against Magnaporthe grisea, the causal agent of rice blast disease.

These studies raised the question: what is the function of PSY in rice? Our new PNAS study shows that rice PSY8 promotes root growth under favorable conditions but is repressed during osmotic stress, allowing rice to shift from growth to stress adaptation.

Bacterial RaxX competes effectively with plant PSY in binding to the PSY receptors, PSYR2 and PSYR3, indicating that RaxX is also perceived by PSYRs in Arabidopsis.

In Arabidopsis, these receptors represses plant growth and activate stress-response genes when they are not repressed by their peptide hormone ligands.https://www.science.org/doi/10.1126/science.abq5735

A synthetic sulfated RaxX derivative comprising 13 residues, highly conserved between RaxX and PSY, induces root growth in Arabidopsis and rice in a manner similar to that triggered by PSY. A Xanthomonas strain lacking raxX is impaired in virulence.

What is the molecule recognized by XA21? Rory Pruitt led the identification of a gene, called RaxX (required for activation of XA21-mediated immunity) encoding a small sulfated peptide.

Wow! The rice RALF7 peptide provides positional information for infection initiation for M. oryzae.

Are you looking for a postdoc exploring the cell biology of development, defining how cells change shape and move? Do you want to develop a research program & teaching skills preparing you for a position at a college or small University? Our new NIH grant will support those goals 1/n Please share

Good. Restore those cancelled grants

ACLU@aclu.org

BREAKING: We're suing Secretary Robert F. Kennedy, Jr. and the National Institutes of Health Director for their ideologically-driven termination and censorship of biomedical research grants. Targeting views the government disagrees with for not aligning with a political agenda is unconstitutional.

Are you a postdoc or early-career scientist? The Keystone Symposia Fellows Program may be for you. Career development. SAB meetings with leaders in your field. 1:1 mentorship. A community of Fellows committed to each other's growth. Applications close in 2 weeks on Sept. 28.

Good news. Still, the article notes that additional reviews need to be completed by the Environmental Protection Agency before American chestnuts can be distributed to individuals or used for wider restoration projects. However, this recent decision will be immediately beneficial to researchers.

After years of testing, USDA has just approved releasing GMO American chestnut trees, potentially giving us the chance to bring back an iconic species destroyed in the early 20th century by an imported disease. (Chauvinistic note: I've had American chestnuts, and they are better than European ones.)

Just had my daily reminder of how wonderful the NIH peeps are who handle all of the work involved in managing grants for those of us out here in extramural land. The NIH staff really are the best humans, working so hard to ensure that the science can continue in incredibly challenging times.

Not my usual 'cup of tea'. I preface this simply because I found Gina Kolata's article about ovarian cancer worth passing along for 2 reasons. 1st, we—my wife and I—are humans of a certain age. 2nd, the topic of cancer, scares the shit out of almost everyone. FYI. www.nytimes.com/2026/07/28/h...
