SANCHOLLE M; DALPE Y. 1993. TAXONOMIC RELEVANCE OF FATTY-ACIDS OF ARBUSCULAR MYCORRHIZAL FUNGI AND RELATED SPECIES. MYCOTAXON. 49:187-193. Address: SANCHOLLE M, UNIV SCI & TECHNOL LILLE,CRYPTOGAMIE PHYTOPATHOL LAB,F-59655 VILLENEUVE DASCQ,FRANCE
Fatty add analyses were conducted on the spores of ten Zygomycetes species including seven arbuscular mycorrhizal fungi (AMF) of the genus Glomus a saprobic zygosporic species, Endogone pisiformis, and species of the genera Acaulospora and Scutellospora. Eighty percent of the total fatty adds of thew fungi consisted C16:0, C18:0, C:18:1 and C:18:2. Alpha and gamma isomers of linolenic acid were only present in E. pisiformis spores. The trans configuration of the monounsaturated fatty adds (C16:1 and C18:1) is, far the first time, reported for AMF. Taxonomic aspects of the fatty add distribution in AMF spores and related species are discussed.
