Biochemical changes during fungal sporulation and spore germination. I. Phenyl methyl sulfonyl fluoride inhibition of macroconidial germination in Microsporum gypseum.
Macroconidia of Microsporum gypseum release free amino acids into the medium during germination. A single alkaline protease is also found in the germination supernatant fraction. The purified protease is capable of hydrolyzing isolated spore coats in vitro. Phenyl methyl sulfonyl fluoride (PMSF) is an effective inhibitor of the protease. Incorporation of PMSF at 10(-4)m into the germination sys...
متن کاملChanges in Microsporum gypseum mycelial wall and spore coat glycoproteins during sporulation and spore germination.
Ethylenediamine-soluble glycoproteins were extracted from isolated Microsporum gypseum hyphal walls during sporulation and from spore coats before and after germination. This study was carried out to identify a sporulation-specific cell wall protein that possibly served as a substrate for the alkaline protease which initiated the macroconidial germination of this fungus. Analyses revealed that ...
متن کاملRibonucleic acid synthesis during fungal spore germination.
Spores of several fungi were examined in an effort to understand the role of RNA in the biochemical events occurring early in germination. RNA synthesis appeared to be an essential requirement for germination in Neurospora crassa and Aspergillus nidulans but not in Alternaria solani and Peronospora tabacina. Gross changes in the relative amounts of the various molecular species of RNA were not ...

متن کاملSporulation in bacillus subtilis. Antigenic changes during spore formation.
1. Antisera, prepared against extracts of cells and spores of Bacillus subtilis, were used in immunoelectrophoretic studies of the changes occurring in cell extracts during the course of spore formation. 2. At least 15 antigens could be detected in vegetative-cell extracts by the antiserum prepared against cell extracts and at least seven could be demonstrated in spore extracts by the homologou...
