The paper investigates how starch granules form a sheath around the pyrenoid in Chlamydomonas reinhardtii and identifies SBE1 as essential for circumferential growth.

Knocking out Nicotiana benthamiana RBCS genes and complementing with algal RBCS2 enables rapid EPYC1 condensate formation, and the kinase KEY1 consolidates condensates to one per chloroplast.

This study uses super-resolution microscopy to reveal nanoscale protein domains and CO2-dependent structural changes in Chlamydomonas pyrenoid-traversing membranes.

The paper identifies RBMP2 as essential for forming the reticulated membrane region in the algal pyrenoid, which is critical for CO2 delivery and growth.

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

This paper identifies SAGA1 and SAGA2 as proteins necessary for localizing the starch sheath to the pyrenoid in Chlamydomonas reinhardtii, showing their redundant roles in starch sheath biogenesis.

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.

The paper shows that the Arabidopsis amino acid transporter UmamiT20 contributes to susceptibility to the necrotrophic fungus B. cinerea by facilitating amino acid transport, suggesting a broader role for nutrient transporters in plant-pathogen interactions.

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.

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

The paper systematically characterizes gene function in a photosynthetic organism by analyzing mutant phenotypes across diverse conditions and linking them to functional pathways.

This study identifies the structural basis of Rubisco phase separation in the pyrenoid by analyzing interactions between Rubisco and its linker protein EPYC1 in Chlamydomonas reinhardtii.

The paper creates a genome-wide mutant library for Chlamydomonas reinhardtii to identify genes essential for photosynthesis, finding 303 candidate genes, including 21 novel ones.
