E.coli mutants deficient in ribose phosphate isomerase can only grow on glycerol when they express a functional rubisco. This provides a tool for screening Rubisco sequence variants. Doing so reveals rare mutations that improve CO2 affinity. There is still room for Rubisco engineering! #PlantScience
What limits rubisco function? Is it the chemical mechanism? Evolution? In this paper, @prywes.bsky.social et. al explore this question by assaying >99% of single amino acid mutants in Form II rubisco (1/7) doi.org/10.1038/s415...

Great Barrier Reef fish reveal that large-scale macroecological patterns have changed significantly 🐟🐠
We found that changes in latitudinal diversity gradient & rising species turnover were strongly correlated with shifts in coral composition

Emergent patterns of reef fish diversity correlate with coral assemblage shifts along the Great Barrier Reef - Nature Communications
Coral reefs have been severely affected by anthropogenic stress. Using long term data from the Great Barrier Reef, this study found temporal changes in the latitudinal diversity gradient, and stronger...

So cool !
In one year, I genetically engineered the boring Arabidopsis into a beautiful ornamental flower 🧬🌹
Here is how and why I gave this model organism a visual upgrade 🧵(1/7)

Here is our latest preprint. Fusions of Cas9 to specific viral 5' exonucleases increase homology directed repair 30-fold in transient and 10-fold in stable transformations. Making non-selectable knock-ins and gene replacements possible. Congrats to the whole team! www.biorxiv.org/content/10.1...

C4 photosynthesis is beautifully intricate/complex but has evolved repeatedly. How did evolution change gene expression to enable this? Basically, C4 genes acquire elements in cis that plug them to existing cell identity networks.
