Attention Nicotiana benthamiana users! Certain strains of Agrobacterium (e.g. GV3101-pMP90) induce glandular trichomes because of cytokinin production by Agrobacterium. As this can influence assay outcome, we recommend testing several strains. See our preprint: www.biorxiv.org/content/10.1...

Cytokinin-mediated trichome initiation in Nicotiana benthamiana upon Agrobacterium tumefaciens infiltrationInfiltration of Agrobacterium tumefaciens in leaves of Nicotiana benthamiana has become a standard method for transient expression in plants. Like many Solanaceae species, N. benthamiana develops on i...www.biorxiv.org

Avocados come in 2 varieties - A-types start each day female and switch to male midday. B-types do the reverse. In work just published from the last chapter of my PhD, we show this system evolved 40+million yrs ago and is regulated by alleles of 1 transcription factor www.pnas.org/doi/10.1073/...

Balanced polymorphism in a floral transcription factor underlies the ancient rhythm of daily sex alternation in avocado | PNASIn avocado and certain wild relatives in Lauraceae, a highly synchronized daily rhythm of floral sex timing promotes cross-pollination between two ...www.pnas.org

“Seven days after the girl’s medical team infused trillions of viruses carrying the recipe for the base editor into her spinal fluid, she died of a severe immune reaction linked to the therapy…” This, in @science.org, is an important and tragic story. (It’s also an incredibly well reported one.) 🧪

Hot off the press (so to speak)! Where we described new factors that inhibit meiotic crossovers near centromeres rdcu.be/fvHfe thread👇

The deSUMOylase SPF2 and the cohesin regulators SGO2 and CTF18 suppress crossovers near centromeresNature Plants - Gamboa et al. identified three proteins that restrict meiotic crossovers near centromeres. This finding suggests that cohesion regulation plays a role in this suppression and...rdcu.be

1/5 Every paper has a story. Ours started with a dataset and ended with a conceptual advance. But what I'm most proud of is the development of the people behind it. www.pnas.org/doi/10.1073/...

Excited to share our latest publication! 🎉 Here @sophiezoe.bsky.social reveals an early developmental time window determining initial growth direction of lateral roots. Wonderful collaboration with @wabniklab.bsky.social and @matesf.bsky.social lab www.pnas.org/doi/10.1073/... @cibss.bsky.social
