Genetic Diversity of Pyrenophera tritici-repentis Isolates, the Causal Agent of Wheat Tan Spot Disease from Northern Iran
Background: The tan spot disease of wheat caused by Pyrenophera tritici-repentis has become a major disease in most wheat growing areas worldwide. Objectives: Here we used ISSR and RAPD markers to study the genetic diversity of 34 P. tritici-repentis isolates collected from North of Iran. Materials and Methods: The leaves having the typical symptoms of tan spot disease were collected and after...

متن کاملControl of Bipolaris Oryzae the Causal Agent of Rice Brown Spot Disease Via Soil Streptomyces Sp. Isolate G
Bipolaris oryzae causes rice brown spot disease which reduces rice yield with substantial global impact. Streptomycetes isolated from rice fields of Guilan Province, Iran, showed antifungal activity against the tested pathogen. From five active Streptomyces spp. isolates, isolate G showed high antagonistic activity. To determine its taxonomical identity, its colonies character...
متن کاملPurification of Host- Specific Toxin from Iranian Isolates of Alternaria alternata, Causal Agent of Brown Spot Disease of Tangerine
Brown spot disease caused by Alternaria alternata (Fr.: Fr.) Keissl is a serious problem forproduction of tangerines and tangerine hybrids in Iran. The Tangerine pathotype causes brownspot disease on young leaves and immature fruits of limited varieties of mandarins and tangerines(Citrus. reticulata Blanco). Specificity in the interaction between tangerine and the pathogen isdetermined by a hos...
