A total of 43 isolates of the wheat leaf rust fungus, Puccinia triticina Eriks, collected from Ethiopia and Germany were analysed for their genetic diversity using the amplified fragment length polymorphism (AFLP) technique. Out of 18 EcoRI/MseI primer combinations screened, 15 produced 219 highly polymorphic fragments. The average AFLP difference between pairs of the leaf rust isolates (26 fro...

Wheat stem rust (Puccinia graminis f. sp. tritici Eriks. and E. Henn.) is one of the most destructive diseases world-wide. Races belonging to Ug99 (or TTKSK) continue to cause crop losses in East Africa and threaten global wheat production. Developing and deploying wheat varieties with multiple race-specific genes or complex adult plant resistance is necessary to achieve durability. In the pres...

Leaf rust is one of the most important diseases of wheat and is caused by Puccinia triticina, a highly variable rust pathogen prevalent worldwide. Decoding the genome of this pathogen will help in unraveling the molecular basis of its evolution and in the identification of genes responsible for its various biological functions. We generated high quality draft genome sequences (approximately 100...

Four rust raxa in 3 genera and one form genus are newly recorded for Iran. Among these, Melampsoridium is a new genus for the Iranian rust flora. M. carpini on Carpinus sp., Coleosporium inulae on Inula salicina ssp. aspera, Puccinia saniculae on Sanicula europea and Uredo Otostegiae on otostegia persica are repoted for the first time in Iran. Number of urediniospore pores formerly believed 2 i...

Surveys were carried out in garlic cultivation areas of Gaziantep province April 2018 and 2019 to determine the prevalence fungal diseases garlic. After isolation process was conducted according routine mycological methods, fungi identified their cultural morphological characteristics. Fungi belonging genera Fusarium, Rhizoctonia, Macrophomina Puccinia determined production areas. The most prev...

Stem rust caused by Puccinia graminis f. sp. tritici is an important disease of wheat in the world. This also common Sinop province Turkey. The pathogen forms new races and these may overcome resistance present cultivars. For sustainable production, identification stem necessary. During 2016 2017, surveys were conducted wheat-growing areas from diseased plants, 42 single uredospore pustule isol...

The main objective of this work was to evaluate the variability of the southern rust pathogen Puccinia polysora in Brazil, based on its virulence on a set of maize (Zea mays) cultivars. Sixty single pustule isolates, from different areas of occurrence of southern rust, were evaluated for their virulence to 50 maize experimental hybrids. Six cultivars showed a clear distinction between susceptib...
