Ultrastructure of conidia and hyphal cells of Ophiostoma querci isolates with respect to their ageing

Krystyna Przybył, Krystyna Idzikowska

Abstract


Ultrastructural ohservations of isolates presented in this paper revealed that conidia and hyphaae taken from 6-day old end 30-day-old cultures differed in morphology of membranous bodies and occurrence of electron opaque bodies (EOB). Signle Sporothrix conidia of 30-day-old cultures exhibited a shrinkage of cytoplasm and endospores. It is possible that formation of endospores might result in producing extra cell walls to protect the shrinking or fragmenting cytoplasm.
