Le corps paranucléaire des gamètes géants d'Allomyces javanicus traité à l'acide borique

Summary

The gametes ofAllomyces javanicus exhibit a nuclear cap essentially made of ribonucleoprotein with sulphydryl groups.

When dipped in phosphate buffered solutions of boric acid M/20–M/400, the male and female gametangia ofAllomyces liberate giant male and female gametes. Such giant gametes exhibit either a single regular nuclear cap (with 2 or 3 nuclei) or a massive and irregular basophilic formation (with 4–10 nuclei).

Boric acid may interfere with ribonucleic acid, essential constituent of the nuclear cap, during the cleavage of the gamete-units in the gametangia.
