摘要

Algae, as crucial primary producers in aquatic ecosystems, are increasingly transforming into algal blooms due to the combined pressures of climate change and anthropogenic activities. Despite the recognition of resting cells (RCs) as key mediators in bloom resilience, their ecophysiological mechanisms and interactions with pollutants remain largely understudied. This review establishes a phylum-specific classification of resting cells (RCs) by examining the types and dormancy strategies of algal RCs, encompassing cyanobacterial akinetes, diatom resting spores, Chlorophyta hypnospores, and dinoflagellate cysts. The review explores RCs resting strategies, including morphological adaptation, physiological adjustment, and molecular responses. The germination thresholds of these RCs are governed by a complex interplay of factors, including light, temperature, oxygen, nutrients, hormones, and biological disturbances. Notably, pollutants like heavy metals, persistent organic pollutants, antibiotics, microplastics, and endocrine-disrupting compounds significantly impact RC formation, survival, and germination, potentially altering aquatic ecosystems and exacerbating algal blooms.
