A REPORT ON THE RUST FUNGI OF HAMEDAN PROVINCE (IRAN)
Based on the morphological study of specimens of rust fungi collected during 2002-2003, a contribution is made to the rust fungus flora of Hamedan province: Uromyces inaequialtus var. ecbatanensis is described as new taxon. Melampsora allii-fragilis and Uromyces acantholimonis var. zagrosica are new reports for Iran. New observations on already known species were made: the aecia of Melampsora e...
متن کاملNew Rust Disease of Korean Willow (Salix koreensis) Caused by Melampsora yezoensis, Unrecorded Pathogen in Korea
During the growing season of 2015, leaf specimens with yellow rust spots were collected from Salix koreensis Andersson, known as Korean willow, in riverine areas in Cheonan, Korea. The fungus on S. koreensis was identified as the rust species, Melampsora yezoensis, based on the morphology of urediniospores observed by light and scanning electron microscopy, and the molecular properties of the i...
متن کاملA new species of Melampsora rust on Salix elbursensis from Iran
A rust fungus was found causing stem cankers on 1to 5-year-old stems of Salix elbursensis in the north west of Iran. The rust also forms uredinia on leaves and flowers of the host willow. Light and scanning electron microscopy revealed that the new rust is morphologically distinct from several Melampsora species occurring on the willows taxonomically close to S. elbursensis, but indistinguishab...
متن کاملAbundant Pathogenic Variation in the New Hybrid Rust Melampsora xcolumbiana on Hybrid Poplar.
ABSTRACT The recently described rust hybrid Melampsora xcolumbiana was discovered as a result of its novel pathogenic variation on Populus trichocarpa x P. deltoides (TxD) hybrid poplar. To characterize this pathogenic variation, 10 commercial TxD clones, all F(1) clones, were chosen as host differentials. Fourteen mononuredinial isolates of Pacific Northwestern field collections of M. xcolumbi...
متن کاملAssociation Analysis Identifies Melampsora ×columbiana Poplar Leaf Rust Resistance SNPs
Populus species are currently being domesticated through intensive time- and resource-dependent programs for utilization in phytoremediation, wood and paper products, and conversion to biofuels. Poplar leaf rust disease can greatly reduce wood volume. Genetic resistance is effective in reducing economic losses but major resistance loci have been race-specific and can be readily defeated by the ...
