Some studies on the chromatin and cell wall of the mycetomal micro organisms of Sitophilus granarius (L.) (Coleoptera)

Abstract

Cytochemical studies of the outer membranes and chromatinic material in the inherited, supposedly symbiotic mycetomal micro-organisms of Sitophilus granarius have revealed the presence of considerable amounts of DNA occurring as either consolidated dots or a spongy network. There is also evidence that, at times, the organisms are surrounded by cell walls.
