title: [Physiological and molecular biological mechanisms underlying diapause in aquatic invertebrates].
abstract: The review considers the published data, as well as its own, which demonstrate the abundance and evolutionary conservation of the mechanism of diapause in invertebrates. The ecological reasons for the emergence of diapause in life cycles of hydrobionts are analyzed. The specific physiological features of invertebrate diapausing organisms and the hormonal control of diapause are briefed. The molecular genetic mechanism of diapause is demonstrated by the example of a model species, Caenorhabditis elegans. Recent fundamental discoveries in molecular genetics related to the joint effect of genes and environmental factors on the basic metabolism, choice between the development-diapause alternative, and many other seasonal adaptations in multicellular organisms are discussed. The near discovery of the functional role of daf genes in hydrobionts is postulated. These studies will lead to a deeper understanding of the fine mechanism that underlies photoperiodism and the wider application of diapause phenomenon in theory and practice.
