Intranuclear vesiculation in Collembola


, : Intranuclear vesiculation in Collembola. Monit Zool Ital 1(2): 101-108

Endonuclear vesicles were observed with the electron microscope in the testicular epithelium of an apterygote insect (Collembola). These inclusions originate from the nuclear envelope by delamination and detachment of portions of the inner layer. They subsequently degenerate. The endonuclear vesicles-formation is probably related to the great ergastoplasm-producing activity of the outer layer of the nuclear envelope.

A probe based on 2-(2'-hydroxyphenyl) benzothiazole (HBT) and thiophosphate has been synthesized and used for the ratiometric detection of Hg(2+). The probe was designed in such a way that the excited state intramolecular proton transfer (ESI...
