Geneticist studying karrikin and strigolactone signaling in plants. Opinions are my own.

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 https://t.co/SIHgtrKLSY

@JuanCa_rotenoid Congratulations on you work!

Is zaxinone found in plants outside the grasses? Are zaxinone synthases grass-specific enzymes?

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 https://t.co/BYayQIsbVS

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.

@DrCJ_Houldcroft @scienceshitpost @aero_anna I demand a ratraction!

[Dave Nelson @nelson_lab]

@facette_lab It is!

But also, I can’t unsee this

[Harro Bouwmeester @HarroBouwmeest1]

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 https://t.co/aD6RqWK6X9

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

[Dave Nelson @nelson_lab]

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 https://t.co/C96pMo2cmf

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

@loraleelarios Oooooooh!!!

[Dave Nelson @nelson_lab]

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?

[Dave Nelson @nelson_lab]

@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

[Dave Nelson @nelson_lab]

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

[Dave Nelson @nelson_lab]

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

[Dave Nelson @nelson_lab]

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