Influence de la cytochalasine A sur la composition de fractions subcellulaires d'hyphes en croissance duMucor mucedoL. II. Composition des parois

摘要

Walls of young hyphae ofMucor mucedoL. growing in the presence or absence of cytochalasin A were isolated and their chemical content determined. Cytochalasin A induced modified proportions of various monomers resulting in a reduction of the (neutral sugars + glucuronic acid)/glucosamine ratio. The walls contained less proteins but more chitin–chitosan and phosphate. These modifications are discussed in relation to ultrastructural changes described previously.
