Molecular and cellular mechanisms of diatom response to environmental changes

Abstract. The review is devoted adaptations of diatom under environmental changes and stress factors. Life cycle diatoms influenced by various changes, including in light intensity, temperature, nutrient availability, exposure to infochemicals, algicidal bacteria, viruses. During evolution have evolved many molecular pathways respond factors: altering their metabolism react on abiotic stressors, or producing secondary metabolites protect themselves from competitors predators. Prolonged a factor leads variety disorders cells oxidative stress, disruption photosynthesis, mitochondrial function, protein folding, resulting cell death. It assumed that these mechanisms allowed adapt conditions successfully exist ecosystems for millions years.
