On the gels of each sample, more than 1400 Coomassie Brilliant Blue-stained spots were detected ( Fig. 5 , supplemental Figs. S1 and S2 ). Jan 5, 2022 · Under favorable conditions, resting spores are induced to germinate and release primary biflagellate zoospores, which are required for infection in the field. Thus, the regulation of resting spore germination is a crucial factor for the completion of the pathogen life cycle through infection and disease induction. Spores are dispersed by the wind but their movement and release from the sporangium may be aided by structures called elators, strap-like appendages on the spore that move in response to the absorption and loss of water. Germination of the spore produces a small (~ 1-3 cm) photosynthetic gametophyte that looks like a pin cushion.
Jun 19, 2021 · The germination of spores by amino acids and/or sugars is commonly referred to as “nutrient” germination in the scientific literature (Setlow, 2003). Rode and Forster were the first to provide evidence that some surfactants, especially dodecylamine, strongly induce spore germination and that they were lethal to the germinated spores. Previous work has shown that the katX gene encodes the major catalase in dormant spores of Bacillus subtilis but that this enzyme has no role in dormant spore resistance to hydrogen peroxide.
