🚨 New paper alert 🚨

Although the photosystems are some of the slowest evolving genes on the planet, they are still adaptively evolving!

Have a read to find out more:

Incredible work from @Lizzie__Robbins

The photosystems turn light into life 🌱

We uncover an expansive landscape of adaptive evolution in plant photosystems & reveal how they have been repeatedly evolving to improve their capacity for repair 🔧

📢 Preprint from us at the Kelly lab (in case you missed it!)📢

We engineered improved plant water-use efficiency and biomass accumulation under water-limiting conditions by manipulating co-factor metabolism in stomatal progenitor cells! 🪴🥤🆒

The first step on a path to C4 rice by genome editing ✂️🧬

Huge team effort from @fl_hahn @jethva10 @ritagiuliani @Cousinslab_WSU and Niels Peeters

The latest from us at the Kelly Lab🛑

Rubisco is still improving its efficiency to assimilate CO2📈

... just at a glacial pace of change🧊

This evolutionary insight has important implications for engineering the enzyme🌾

Huge congrats to PhD student @JBouvierPlants for having the strength and resilience to see this through.

👉 Rubisco kinetic evolution is not strongly limited by catalytic trade-off. Other factors are more important.

📣 Hi all – new from our lab… but, same message as before!

🚦Rubisco’s optimisation has been severely restricted by evolutionary factors.

🧪 We should be able to overcome these limitations in the lab… generating better rubisco is possible!

⏱️ Exciting

[Elizabeth Robbins @Lizzie__Robbins]

My first paper is finally out!

We look at the major constraints on the evolution of the chloroplast genome.

Have a read to find out what they are… 🤔

Awesome first paper from PhD student @Lizzie__Robbins!

Here we uncover the major constraints on the evolution of photosynthesis in plants.

And they’re really not what you think they are...

Preprint updated!

Thanks to the reviewers who helped find weaknesses we missed. It’s the same story but it’s back stronger and better now!

TL;DR - Chloroplast adaptation is constrained by the organisation, composition, and expression of its genes.
