Inositol polyphosphates regulate resilient mechanisms in the green alga Chlamydomonas reinhardtii to adapt to extreme nutrient conditions.

In the context of climate changing environments, microalgae can be excellent organisms to understand molecular mechanisms that activate survival strategies under stress. Chlamydomonas reinhardtii signalling mutants are extremely useful to decipher which strategies photosynthetic organisms use to cope with changeable environments. The mutant vip1-1 has an altered profile of pyroinositol polyphosphates (PP-InsPs), which are signalling molecules present in all eukaryotes and have been connected to P signalling in other organisms including plants, but their implications in other nutrient signalling are still under evaluation.

CO Levels Modulate Carbon Utilization, Energy Levels and Inositol Polyphosphate Profile in .

Microalgae have a growing recognition of generating biomass and capturing carbon in the form of CO. The genus has especially attracted scientists' attention due to its versatility in algal mass cultivation systems and its potential in mitigating CO. However, some aspects of how these green microorganisms respond to increasing concentrations of CO remain unclear.
