Cherry-spruce rust caused by (Fr.) Magnus is a serious cone pathogen of Norway spruce [ (L.) Karst.]. The causes great economical losses in seed orchards specialized the production high quality seeds. Germination range aeciospores from populations (spore sources) seven Finnish was tested on water agar and malt at nine temperatures varying between 6–30 °C. temperature spore germination ...

Germination of mutant spores of Bacillus subtilis unable to degrade their cortex is accompanied by excretion of dipicolinic acid and uptake of some core water. However, compared to wild-type germinated spores in which the cortex has been degraded, the germinated mutant spores accumulated less core water, exhibited greatly reduced enzyme activity in the spore core, synthesized neither ATP nor re...

Since the introduction in 1933 (Kluyver and Perquin, 1933) of the shaker flask method of culturing fungi this technique has found widespread use in fungus physiology (Foster, 1949). It was used for spore germination studies by Davies et al. (1948) and Mandels and Norton (1948). The measurement of antifungal activity, however, has been accomplished by the more conventional methods making use of ...

In a separate paper, the changes in the P fractions of bacterial spores (luring geimination weere correlated with the morphological changes which took place at the same time. Germination has heen defined as the over-all period, some 50 to 60 min, extendling from the resting state of the "mononucleate" spore to the vegetative or "binucleate" cell. Thick suspensions (109 spores/ml) of synchronous...

Clostridium perfringens food poisoning is caused by type A isolates carrying a chromosomal enterotoxin (cpe) gene (C-cpe), while C. perfringens-associated non-food-borne gastrointestinal (GI) diseases are caused by isolates carrying a plasmid-borne cpe gene (P-cpe). C. perfringens spores are thought to be the important infectious cell morphotype, and after inoculation into a suitable host, thes...

Freshwater and marine sediments often harbor reservoirs of plant diaspores, from which germination and establishment may occur whenever the sediment falls dry. Therewith, they form valuable records of historical inter- and intraspecific diversity, and are increasingly exploited to facilitate diversity establishment in new or restored nature areas. Yet, while ferns may constitute a considerable ...

Inosine is a more effective germination stimulant than adenosine for spores of Bacillus cereus and B. anthracis (Powell & Hunter, 1955). A crude method of assessment, based on the paper-ionophoresis technique of Wade & Morgan (1954), indicated that extracts from disintegrated resting spores of B. cereus converted adenosine into inosine. This suggested the possibility that inosine might be, in f...
