Characterization of pyrenoid-based CO2-concentrating mechanism in hornworts

Pyrenoids are structures that concentrate carbon dioxide around Rubisco, most commonly studied in green algae such as Chlamydomonas. However, hornworts, one of the three types of bryophytes (along with liverworts and mosses) also have a pyrenoid-based CO2-concentrating mechanism (pCCM), unique among…

Microalgae concentrate CO2 to ameliorate oxidative stress

Choi et al. report that the Chlamydomonas bZIP transcription factor BLZ8 induces the carbon-concentrating mechanism to provide an electron sink pathway, reducing reactive oxygen species production under oxidative stress conditions. Plant Cell. https://doi.org/10.1093/plcell/koab293 By Bae Young Choi,…
