Toward improved CO₂ fixation: A hornwort-derived RbcS motif enables formation of Rubisco condensates
Plant Science Research WeeklyEnhancing photosynthetic CO₂ fixation to increase crop yields is a major focus in plant biotechnology. Notably, several algal species form pyrenoids, phase-separated organelles that boost the activity of the CO₂-fixing enzyme Rubisco by supplying it with concentrated CO₂, thereby making carboxylation…
Characterization of pyrenoid-based CO2-concentrating mechanism in hornworts
Plant Science Research WeeklyPyrenoids 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…
