Phototropin connects blue light perception to starch metabolism in green algae

The paper identifies a blue light signaling pathway in green algae that inhibits starch accumulation via PMSK1 dephosphorylation and GAP1 repression.

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.

The α/β hydrolase domain-containing protein 1 (ABHD1) acts as a lysolipid lipase and is involved in lipid droplet formation

This paper identifies ABHD1 as a lysolipid lipase involved in lipid droplet formation through enzymatic and structural actions on the LD surface in Chlamydomonas.

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.

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.

CO2 supply modulates lipid remodelling, photosynthetic and respiratory activities in Chlorella species

This study examines how CO2 availability affects lipid remodeling, photosynthetic machinery, and mitochondrial respiration in two Chlorella species, revealing divergent responses compared to Chlamydomonas reinhardtii.

Guanosine tetraphosphate (ppGpp) accumulation inhibits chloroplast gene expression and promotes super grana formation in the moss Physcomitrium (Physcomitrella) patens

This study shows that ppGpp accumulation in moss inhibits chloroplast gene expression and causes super grana formation without affecting growth.

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.

ppGpp influences protein protection, growth and photosynthesis in Phaeodactylum tricornutum

This study shows that ppGpp reduces photosynthesis and promotes a quiescent state in diatoms, while inducing a protein protection response.

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.
