A bifunctional coiled-coil protein generates the membrane-within-condensate architecture of the CO2-fixing pyrenoid

The paper identifies MITH1 as a protein that anchors thylakoid membranes into the pyrenoid condensate, revealing how membranes are integrated into biomolecular condensates.

Kinase KEY1 controls pyrenoid condensate size throughout the cell cycle by disrupting phase separation interactions

This study identifies the kinase KEY1 as a regulator of pyrenoid condensate size and dynamics in Chlamydomonas reinhardtii, showing it disrupts phase separation interactions to control condensate dissolution during the cell cycle.

Proteomic analysis of the pyrenoid-traversing membranes of Chlamydomonas reinhardtii reveals novel components

The paper identifies protein components of pyrenoid-traversing membranes in Chlamydomonas reinhardtii using affinity purification and mass spectrometry, and characterizes two novel proteins involved in this structure.

Biogenesis, engineering and function of membranes in the CO2-fixing pyrenoid

This study identifies proteins involved in pyrenoid membrane biogenesis and shows their role in CO2 delivery, with implications for engineering functional pyrenoids in crops.
