Ultrastructure and cytochemical localization of laccase in two strains of Leptosphaerulina briosiana (Pollaci) Graham and Luttrell.

Abstract

Substrate specificity tests were used to identify the presence of laccase in two strains of Leptosphaerulina briosiana (Poll.) Graham and Luttrell, an ascomycete which causes leaf spot in alfalfa. Cytochemical localization of monophenol monooxygenase (laccase) as well as the ultrastructures of the two strains were investigated. Laccase was observed in the outer layers of the cell walls of both strains. The ultrastructures of vegetative hyphae of both strains were typical of those found in most ascomycetes.
