How do karrikins and strigolactones control plant growth? A beautiful structure-function analysis by graduate student @SunhyunChang reveals a major regulatory domain that specifies the development “outputs” of SMXL proteins

🎉check out our latest exciting collaborative study published @ScienceMagazine with Dudareva group (Purdue U with @ShabekLab @ucdavisbiology funded by @NSF): communication in plants relies on a KAI2-mediated signaling pathway science.org/doi/10.1126/scie…

Our latest work from Dr. Qingtian Li @Qingtia95731962
We find that degradation-resistant SMXL proteins attenuate strigolactone signaling by interfering with targeting of other members of the SMXL family by D14-MAX2.

Pretty proud of this review that @watersmt and I wrote on karrikin signaling and the (still) mysterious KAI2 ligand. 18 years after the discovery of karrikins in smoke, this field has come a long way!
Final version is out now nph.onlinelibrary.wiley.com/…

Teaching a freshmen seminar this quarter and I want to talk about bad genetics portrayals in movies and why they’re inaccurate. What are your favorites?

✅ Genetically engineered bloodthirsty sheep (and it’s catching)
✅ New Zealand
✅ Great one-liners
✅ Sheep farts to the rescue?!

Way to go, Michael!

Our new paper @NaturePlants is out! We combined structure function approaches & CRISPR editing in plants to elucidate the conformational switch of MAX2 #ubiquitin ligase in #strigolactone path & we found a primary metabolite that unlocks the ligase nature.com/articles/s41477-0…

How parasitic #plants can sense host plants via root exuded chemicals with a picomolar affinity? Our recent work with @nelson_lab looks at the activation mechanism of #strigolactone receptors in plants to answer this question. @JFroggert @diwakarshukla doi.org/10.1021/acs.jcim.1c0…

Our addition to the growing toolkit for characterizing strigolactone receptors. We love transient expression in benthi, so why not use CRISPR to make it a better platform? Led by grad student Alex White with help from Jose Mendez and @khosla_aashima dx.doi.org/10.1002/pld3.389
