Some organisms gave up and invented air-conditioning for it: Plants like maize and sugarcane evolved C4 photosynthesis, an elaborate biochemical turbocharger that pumps CO₂ into special cells so RuBisCO never even sees oxygen.

@MedBennett @dwallacewells 1) C4 photosynthesis doesn't benefit from increased CO2 levels. Anywhere you grow corn/maize there is no benefit. Maize is primary food source in much of Africa. 2) More photosynthesis does not equal more yield. High night time temperatures drive yields down. Talk to any farmer.

Very happy to share that our latest publication on the evolution of C4 photosynthesis is out now. It was such a pleasure working with the amazing Joseph Swift, Joe Ecker, @tinaschreier.bsky.social, and @jmhibberd.bsky.social. www.nature.com/articles/s41...

"High-yielding crops, such as maize, use C₄ photosynthesis. Rubisco is abundant, but oxygen is not, and when the four-carbon compounds are broken down, the released CO₂ can be fixed by Rubisco more effectively than in C₃ plants."

Interesting paper on the evolution of C3 and C4 photosynthesis from the Hibberd and Ecker groups. C4 photosynthetic programs may have co-opted cis-elements found in C3 photosynthetic species. Raising the question: how can C4 photosynthesis be engineered in C3 species? www.nature.com/articles/s41...

My paper is finally published in CNAS! It’s a deep dive into the cis regulatory drivers for c4 photosynthesis. Turns out - lotta ways to evolve cell type specificity. www.pnas.org/doi/10.1073/...

Eleocharis vivipara uses C3 #photosynthesis under water and C4 photosynthesis on land. Studying this plasticity helps Liu et al. gain insights into the genetic basis of the transition, with implications for crops. doi.org/10.1111/jipb... #PlantScience #OpenAccess

This reminds me of the rewiring of existing regulatory networks during the transition from C3 to C4 photosynthesis, which is also accompanied by developmental innovation.

Saturn's rings up until recently were considered an extremely ancient thing, a very long-lasting phenomenon. It's interesting that they are probably younger than most dinosaur skeletons, and will be outlived by C4 photosynthesis.

You'd expect to see C4 photosynthesis or eyes, simply because of how often they evolved independently on earth.

Given how often eyes evolved, you'd guess that eyes would be more likely. C4 photosynthesis evolved 40 separate times as well.

About 500 million years from now, about 95% of all plant life starts to go extinct, only the C4 photosynthesizers able to survive. Everything that depends on photosynthesis starts to die off as well. 300 million years later, C4 photosynthesis will become impossible.

C4 photosynthesis, which evolved over 60 different times, and is far superior to the much more common C3 photosynthesis pathway. The 5% of C4 biomass accounts for almost a quarter of all carbon fixation. In 500 million years, only C4 will survive. en.m.wikipedia.org/w/index.php?...

Yes! I've been doing a half-assed (quarter assed? eighth assed?) attempt at learning German and recently learned that Kranz = wreath, as in C4 photosynthesis plant structure. I had learned it as "Kranz wreath", like it was someone's name. Mind was blown!
