Phytophthora kernoviae oospore maturity, germination, and infection.
Limited information is known on the basic biology of the recently described Phytophthora kernoviae that produces homothallic oospores. In this study, different P. kernoviae isolates were used to investigate oospore maturity, germination, and infection. All isolates produced oospores in V8 broth at 20°C in the dark by 6d. Oospores also formed at 10 and 15°C, but did not form at 25 and 28°C. Cont...
متن کاملSensitivity of North American Isolates of Phytophthora erythroseptica and Pythium ultimum to Mefenoxam (Metalaxyl)
Since their introduction in the late 1970s, phenylamide fungicides have been used effectively to control diseases caused by the Peronosporales. These fungicides have a very specific mode of action; inhibiting fungal ribosomal RNA polymerases (7). Because of this specificity, there is a relatively high risk that resistance to the fungicide may appear quickly in the target fungal population (3). ...
متن کاملPsVPS1, a Dynamin-Related Protein, Is Involved in Cyst Germination and Soybean Infection of Phytophthora sojae
Plant pathogens secrete effector proteins to suppress plant immunity. However, the mechanism by which oomycete pathogens deliver effector proteins during plant infection remains unknown. In this report, we characterized a Phytophthora sojae vps1 gene. This gene encodes a homolog of the Saccharomyces cerevisiae vacuolar protein sorting gene vps1 that mediates budding of clathrin-coated vesicles ...
متن کاملThe Effect of Wounding, Temperature, and Inoculum on the Development of Pink Rot of Potatoes Caused by Phytophthora erythroseptica
Pink rot, caused by Phytophthora erythroseptica Pethybr., is an important disease of potato (Solanum tuberosum L.) (20). The name of the disease describes a characteristic and diagnostic pink color that appears after infected tissue has been cut and exposed to air for 20 to 30 min (8,12,17). Other symptoms of pink rot include dark discoloration of the skin and lenticels of infected parts, purpl...
متن کاملUltrastructural aspects of encystation and cyst-germination in Phytophthora parasitica.
Encystation in Phytophthora parasitica can be divided into 3 stages. In the first, the zoospores line their peripheries with flattened vesicles and nbrillar vacuoles in preparation for encystation. In the second stage, as the zoospores round up and shed their flagella, an initial wall is produced which takes the form of the mature cyst wall in thickness, but not in density. The participation of...
