When a receptor becomes its own evil twin. New work from the recent Dr. Alex White Dominant-negative KAI2d paralogs putatively attenuate strigolactone responses in root parasitic plants academic.oup.com/pcp/article-ab…

@JuanCa_rotenoid Congratulations on you work! Is zaxinone found in plants outside the grasses? Are zaxinone synthases grass-specific enzymes?

My dream came true. Here we uncover the first apocarotenoid receptor(s), a novel ligand for the SL-receptor D14, and the first endogenous KARRIKIN Ligand! DWARF14 and KARRIKIN INSENSITIVE2 mediate signaling of the apocarotenoid zaxinone in Arabidopsis biorxiv.org/content/10.110…

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 biorxiv.org/cgi/content/sh…

🎉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/sc…

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. sciencedirect.com/science/articl…

@DrCJ_Houldcroft @scienceshitpost @aero_anna I demand a ratraction!

Erm, how did Figure 1 get past a peer reviewer?! frontiersin.org/articles/10.33… H/T @aero_anna

@facette_lab It is! But also, I can’t unsee this

This is a great paper, and has one of the most gorgeous plant cell movies I have ever seen (showing phragmoplast and cortical microtubules)

Proud of the fantastic work of PhD student Changsheng Li and collaboration with great international team of scientists, here it is: Maize resistance to witchweed through changes in strigolactone biosynthesis science.org/doi/10.1126/sc…

@FrannyBarbs @SeedBarrett @watersmt We’re no @ThisSunOfYork, but we try

@nelson_lab @SeedBarrett @watersmt Love the puns in the conclusion section!

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/doi/epdf/10.11…

@watersmt @ThisSunOfYork If only the train cud steer away from them. I hope they moove beefore you lose your head.

@ThisSunOfYork I can vache for that.

On my way to examine a thesis at University of Nottingham… or at least, I would be, if the cattle hadn’t invaded the railway line 🤣 I didn’t cownt on being delayed…

@loraleelarios Oooooooh!!!

@nelson_lab I found this one terrifying as a little kid and find it hilarious now ✅ genetic serum ✅ monster giant killer rabbits

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?

@BazzleBradley @SweigartAndrea Gattaca is definitely in, but the science is pretty plausible (and the social ramifications) so it will go against the theme a bit. It also has that perfect tag line: “There is no gene for the human spirit.” I suspect this is correct. It’s polygenic.

@bjjanssen I’m all about the ludicrous

✅ Alien DNA ✅ Evolution without all that boring waiting around for millions of years for something interesting to happen ✅ Shampoo to the rescue

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

@bjjanssen Honestly, I love the rock and will watch about any movie he’s in.
