Diatom cell walls are diverse and unique, providing the basis for species identification supporting ecological economic value of diatoms. However, these important structures sometimes change in response to environmental fluctuations, especially under salt adaptation. Although studies have shown that salinity induces morphological plasticity changes diatom walls, most research has focused on physiological responses rather than molecular mechanisms. In this study,

ABSTRACT Environmental transitions, such as the salinity divide separating marine and fresh waters, shape biodiversity over both shallow deep timescales, opening up new niches creating opportunities for accelerated speciation adaptive radiation. Understanding evolutionary genetic underpinnings behind habitat transitions is therefore a central question in biology. We used time-resolved transcriptomics to contrast hyposalinity stress responses of two ecologically important diatoms: Skeletonema marinoi has ancestry but recently invaded brackish whereas Cyclotella cryptica freshwater can withstand much broader range. S. less adept at mitigating even mild compared C. , which distinct mechanisms rapid mitigation hyposaline long-term growth low salinity. show that cellular underlying tolerance, allowed diversification across habitats worldwide, includes elements are conserved variable diatom lineage. The balance between ancestral lineage-specific environmental phytoplankton have likely shaped marine–freshwater on timescales and, contemporary will determine lineages survive adapt changing ocean conditions.
