title: Colonial growth and ramihyphin A-induced changes in cell walls of Neurospora sitophila.
abstract: Colonial growth of Neurospora sitophila phenotypically induced by ramihyphin A is accompanied by marked changes in the contents of DNA, RNA and proteins in the mycelium, and in the relative proportion of hexoses in cell wall hydrolysates. The glucosamine/glucose ratio is also characteristic for colonial growth. X-ray analysis of cell walls showed that ramilhyphin A suppresses the crystalline arrangement of chitin in cell walls. A combination of microbiological, biochemical and physico-chemical methods yielded a general picture of the changes accompanying the colonial growth of Neurospora sitophila.
