Изменение электрокинетических свойств клеточных ядер в процессе сперматогенеза тутового Bombyx mori L. (Lepidoptera: Lymantriidae) и дубового Antheraeapernyi Guérin (Lepidoptera: Saturniidae) шелкопрядов

Abstract

Bioelectrical properties of male gametocyte nuclei of oak and Chinese silkworms during pupal development have been studied for the first time. Data obtained were compared with the intensity of oxygen consumption bythe pupa. It was observed that during pupal development, electrophoretic mobility of gametocyte nuclei changes similarly in both species. The lowest mobility was observed at the beginning of the development; in the following days it gradually increased, reaching maximum on the penultimate day of incubation. No mobility was detected on the last day of development. Electrophoretic mobility was found to correlate with metabolic activity of the nucleus, which was estimated by increased oxygen consumption rate. The connection between 3-potential of the nucleus and its metabolic activity is confirmed.
