A Variant of the MenB Strain of Synechocystis sp. PCC 6803 Disrupts a Stress Response Pathway Allowing DMPBQ to Occupy the A1 Sites of Photosystem I
Phylloquinone (PhQ) plays a unique role in photosynthesis as the A1A and A1B intermediates
in light-driven electron transfer in Photosystem I (PSI). When PhQ biosynthesis is
inhibited by deletion of t...

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! academic.oup.com/jxb/advance-...
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.

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! #lsuscience www.biorxiv.org/content/10.1...

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. www.biorxiv.org/content/10.1...

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! @lsubiosci.bsky.social
