Lipid body content and persistence of chlamydospores of Fusarium solani in soil.

Chlamydospores of Fusarium solani f. sp. pisi. low or high in lipid content, were produced in soil from "low and high reserve" macroconidia, respectively. The development of "low and high reserve" populations of macroconidia and chlamydospores in soil was studied. The rate of conversion of macroconidia into chlamydospores is influenced by the lipid content of the macroconidia. The long-term persistence of chlamydospores in soil seems to be independent of the lipid content of the chlamydospore cells.
