Chlamy never ceases to surprise me! Our new preprint tracks dim-day acclimated Chlamy populations as they face sudden bright days. See how the alga bounces back from severe photodamage and a weird empty stroma phenotype to divide successfully by nightfall. doi.org/10.1101/2025...
Light on its feet: Acclimation to high and low diurnal light is flexible in Chlamydomonas reinhardtii
Chlamydomonas acclimates to repeated low (LL) or high light (HL) days by changing the abundance of photosynthetic complexes and the ultrastructure of its thylakoid membranes. These phenotypes persist ...

Postdoctoral researcher @sunnyjoydupuis.bsky.social, PhD '25 Microbiology, writes about the Merchant Lab and @qb3-berkeley.bsky.social scientists peeking in on algae at night to discover how the organisms prepare for another stressful day on the job.

What do algae do after a long day of photosynthesis?

The Sabeeha Merchant lab & @sunnyjoydupuis.bsky.social tracked them day & night. These tiny powerhouses prep for stress in their sleep—findings that could reshape how we see global carbon cycling.

Airyscan microscopy of chlorophyll fluorescence in Chlamy cells acclimated to diurnal low light or excess light taken in the daytime or the nighttime. The cells are outlined with a dotted white line, each containing a single cup-shaped chloroplast, which is outlined in green.

Check out this piece I wrote with @qb3.bsky.social’s awesome science communication team *highlighting* (pun intended) recent work in @theplantcell.bsky.social by Valle Ojeda and yours truly! 🌱🦠🔬
