Pathotypes, Distribution, and Metalaxyl Sensitivity of Phytophthora sojae from North Dakota

Sensitivity 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). ...

Genetic Diversity of Phytophthora Sojae in Iran

Objective: The aim of this study was to estimate genetic variability and phonetic relationships of 50 isolates of P. sojae from Iran. Methods: During 2005–2007, 142 isolates of Phytophthora sojae were collected from soil samples and diseased soybean plants from Lorestan, Mazandaran, Golestan and Ardabil provinces. Races of the isolates were determined. DNA of P. sojae...

Variation in structure and activity among elicitins from Phytophthora sojae.

SUMMARY Transcripts encoding elicitin-like protein domains were identified from similarity searches of Phytophthora sojae expressed sequence tags and were characterized with regard to molecular structure and elicitor activity. The P. sojae elicitin family consists of at least nine genes with products similar to previously described elicitins (SOJA-2, SOJB, SOJ2, SOJ3, SOJ5, SOJ6 and SOJ7) or hi...
