- * The study focused on the roles of Proton Gradient Regulator-like 1 (PGRL1) and Flavodiiron proteins (FLV) in photosynthesis under nitrogen scarcity using the algae Chlamydomonas reinhardtii.
- * Findings showed that pgrl1 mutants maintained better photosynthetic performance compared to flvB mutants when nitrogen was low, indicating that PGRL1 and FLV have opposing effects on photosynthesis and carbon storage during nitrogen deficiency.
The cell wall of plants and algae is an important cell structure that protects cells from changes in the external physical and chemical environment. This extracellular matrix, composed of polysaccharides and glycoproteins, must be constantly remodeled throughout the life cycle. However, compared to matrix polysaccharides, little is known about the mechanisms regulating the formation and degradation of matrix glycoproteins.

- In some algae, there's a special part called the pyrenoid that helps capture CO2 better using a protein called Rubisco.
- Researchers studied the protein BST4, which is found in the pyrenoid tubules, to see how it works with Rubisco.
- They discovered that BST4 isn’t just holding things together but is more like a gate for ions, helping the algae grow better when light changes.
Alka(e)nes are produced by many living organisms and exhibit diverse physiological roles, reflecting a high functional versatility. Alka(e)nes serve as waterproof wax in plants, communicating pheromones for insects, and microbial signaling molecules in some bacteria. Although alka(e)nes have been found in cyanobacteria and algal chloroplasts, their importance for photosynthetic membranes has remained elusive.

Alternative electron pathways of photosynthesis have been proposed to generate additional ATP that is required to sustain CO2 fixation. However, the relative importance of each alternative pathway remains elusive.
