ULTRASTRUCTURE AND GENOTYPIC CHARACTERIZATION OF THE FILAMENTOUS FUNGUS COCHLIOBOLUS-LUNATUS IN COMPARISON TO THE ANAMORPHIC STRAIN CURVULARIA-LUNATA

Although Curvularia lunata is classified as a conidial anamorph of Coc hliobolus lunatus, the electron microscopic studies revealed the ultra structure of both strains to be significantly different. C, lunatus m1 18 grows in the hyphal form characterized by a thick cell wall and num erous lipid bodies. C. lunata forms thinner hyphae of various sizes an d large oval spores. Electrophoretic karyotypes of C. lunatus m118 (th is paper) and C lunata AT46 (Osiewacz, H. and Ridder, R. (1991) Curr. Genet. 20, 151-155) as well as RAPD-PCR analysis with the primer (GTG) (5) indicate close genetic relationship of both microorganisms.
