Pseudostichococcus Stands Out from Its Siblings Due to High Salinity and Desiccation Tolerance

Desiccation and high salinity are two abiotic stressors that related in terms of their effect on water homeostasis within cells. The success certain aeroterrestrial microalgae is influenced by ability to cope with desiccation, some cases, salinity. the Stichococcus clade ubiquitous terrestrial habitats known withstand desiccation stress accumulating secondary metabolites. Nevertheless, it remains unclear if those have a synergistic effect. Hence, we studied various representative taxa clade. results showed contrast other taxa, Pseudostichococcus was able recover fully after without stress. This observation connected elevated proline production under higher proline:sorbitol ratio strains tested. In increasing reduced desiccation. might severe effects (semi)arid regions, where salinization soils an threat also for agriculture. encourage further research be done possible applications this genus bioremediation, as seems comparable halotolerant green algae used purpose.
