Our paper on psbA translation in Chlamydomonas is finally out in
@jxbotany.bsky.social
. Xiaozhuo discovered that chloroplast translational control in plants and algae is more similar than others had predicted. Check it out!

The High Chlorophyll Fluorescence 244 homolog CrHCF244 is required for psbA (D1) translation in Chlamydomonas reinhardtii
Abstract. Translation of psbA, the chloroplast gene that encodes the D1 subunit of Photosystem II (PSII), is important for both PSII biogenesis and repair.

Directed evolution reveals pD1 mutations that boost photosynthesis under salt stress | Plantae
Improving photosynthesis under abiotic stress is essential for enhancing crop productivity. Here, Jiang et al. used short-term accelerated evolution in the cyanobacterium Synechococcus elongatus to…

Our preprint on psbA translational control in algae has been revised. We argue that this process is more similar in algae and plants than previously thought. However, the occurrence of suppressor mutations in Chlamy suggests there's more to learn!

Our revised manuscript about psbA translational control in
#Chlamydomonas
is now available. We assert that algae and plants are more similar than expected (compared to a lot of earlier literature) in their regulation of this key Photosystem II subunit.

Check out this collaborative
#photosynthesis
work from an all star group of collaborators. Evolution happens on the lab bench and we found a surprise in a cyano mutant's Photosystem I. More cool work on this system is coming out soon!
