High impact information on Saprolegnia

• The roles of cortical F-actin in initiating and regulating polarized cell expansion in the form of hyphal tip morphogenesis were investigated by analyzing long term effects of F-actin disruption by latrunculin B in the oomycete Saprolegnia ferax, and detecting localized changes in the cortical F-actin organization preceding hyphal formation [1].
• Ca(2+)-dependent polarization of axis establishment in the tip-growing organism, Saprolegnia ferax, by gradients of the ionophore A23187 [2].
• Saprolegnia parasitica produced 10% oil and contained AA and EPA, respectively, at 19% and 18% [3].
• Survival of A. gracile followed a similar pattern, but the difference between Saprolegnia and control treatments when nitrate was not added was not significant, nor was the nitrate x Saprolegnia interaction [4].
• A trial was carried out to test the efficacy of bronopol against infection of rainbow trout broodstock with the fungus Saprolegnia species [5].

Biological context of Saprolegnia

• The enzyme succinate dehydrogenase (SDH, succinate: (acceptor) oxidoreductase, EC 1.3.99.1) was localized by the combined techniques of cytochemistry and electrom microscopy in the hyphae of a self-parasitizing isolate of Saprolegnia megasperma Coker [6].

Associations of Saprolegnia with chemical compounds

• Effects of nitrate and the pathogenic water mold Saprolegnia on survival of amphibian larvae [4].
• Ultrastructural localization of succinate dehydrogenase in a self-parasitic isolate of Saprolegnia megasperma [6].
• Carbenicillin as an aid in obtaining bacteria-free cultures of Saprolegnia species [7].
• Three major polypeptides of 34, 48 and 50 kDa which appear to copurify with 1,3-beta-glucan synthase activity were isolated by glycerol gradient centrifugation of Chaps-solubilized proteins from the fungus Saprolegnia monoica [8].
• Five chemically modified chitosans were tested for their antifungal activities against Saprolegnia parasitica by the radial growth assay in chitosan-bearing agar, and the fungal growth assay in chitosan-bearing broth [9].

Gene context of Saprolegnia

• Pumilio homologue from saprolegnia parasitica specifically expressed in undifferentiated spore cysts [10].
• Saprolegnia however, besides the glucokinase, contains a mannofructokinase activity that phosphorylates mannose (Km 0.06 mM) and fructose (1 mM) [11].
