DYRKP kinase regulates cell wall degradation in Chlamydomonas by inducing matrix metalloproteinase expression

This study identifies DYRKP kinase as a regulator of cell wall degradation in Chlamydomonas by inducing MMP expression, enabling daughter cell hatching.

Alka(e)nes contribute to membrane lipid homeostasis and resilience of photosynthesis to high light in cyanobacteria

This study shows that alka(e)nes are essential for maintaining membrane lipid homeostasis and photosynthetic resilience to high light in cyanobacteria.

Green Algae CO2 capture is powered by alternative electron pathways of photosynthesis

The paper quantifies the contribution of alternative electron pathways in Chlamydomonas reinhardtii to sustain CO2 fixation, showing chloroplast-mitochondria interaction is the most efficient.

The role of BST4 in the pyrenoid of Chlamydomonas reinhardtii

The paper shows BST4 in Chlamydomonas is an ion channel involved in thylakoid lumenal pH regulation, not a tethering protein for pyrenoid tubules.

Cyclic and pseudo-cyclic electron pathways play antagonistic roles during nitrogen deficiency in Chlamydomonas reinhardtii

This study investigates the roles of cyclic and pseudo-cyclic electron pathways in Chlamydomonas reinhardtii under nitrogen deficiency, showing they have antagonistic effects on photosynthesis and carbon storage.

A plastidial DEAD box RNA helicase plays a critical role in high light acclimation by modulating ribosome biogenesis in Chlamydomonas reinhardtii

This study identifies CreRH22, a plastidial DEAD-box RNA helicase, as essential for high light acclimation in Chlamydomonas reinhardtii by enhancing ribosome biogenesis.

Alternative electron pathways of photosynthesis drive the algal CO2 concentrating mechanism

The paper shows alternative electron pathways in algae generate energy for the CO2 concentrating mechanism, enhancing carbon fixation efficiency.

Fatty acid photodecarboxylase is an ancient photoenzyme responsible for hydrocarbon formation in the thylakoid membranes of algae

The paper identifies FAP as a conserved photoenzyme in thylakoid membranes of algae, responsible for hydrocarbon formation across diverse algal lineages.

ACCLIMATION OF PHOTOSYNTHESIS TO THE ENVIRONMENT 1 regulates Photosystem II Supercomplex dynamics in response to light in Chlamydomonas reinhardtii

This study characterizes ape1 mutants in Chlamydomonas reinhardtii, showing they exhibit PSII photoinhibition and altered thylakoid stacking during light acclimation, suggesting APE1 regulates PSII supercomplex dynamics.

Algal photosynthesis converts nitric oxide into nitrous oxide

The paper shows green microalgae produce nitrous oxide using flavodiiron proteins in the light and a cytochrome P450 NO reductase in the dark.

An oomycete effector impairs autophagy in evolutionary distant organisms and favors host infection

The paper shows an oomycete effector, AVH195, impairs autophagy in diverse organisms, promoting host infection by slowing autophagic flux.
