Puccinia menthae’nin neden olduğu pas hastalığı nane yetiştiriciliğinde verimi ve yağı kalitesini olumsuz etkileyen faktörlerin başında gelmektedir. Hastalıklı bitkilerde yaprakların üst kısmında açık sarı lekeler, altında gövdede turuncu-kahverengi veya siyah püstüller oluşmaktadır. Hastalığın çok şiddetli yaprak dökülmeleri yaygın olarak görülmektedir. Aydın ilinde yapılan gözlemlerde pası ha...

Leaf rust, caused by Puccinia triticina (Pt), and stripe rust, caused by P. striiformis f. sp. tritici (Pst), are destructive foliar diseases of wheat worldwide. Breeding for disease resistance is the preferred strategy of managing both diseases. The continued emergence of new races of Pt and Pst requires a constant search for new sources of resistance. Here we report a genome-wide association ...

The obligate bitrophic fungus Puccinia striiformis f. sp. tritici (Pst) causes stripe (yellow) rust on wheat worldwide. Here, we report a novel fungal strain able to hyperparasitize Pst. The strain was isolated from gray-colored rust pustules, and was identified as Alternaria alternata (Fr.: Fr.) keissler based on a combination of morphological characteristics and multi-locus (ITS, GAPDH, and R...

Differentiation of haustoria on primary infection hyphae of the fungal pathogen Puccinia striiformis was studied in wheat seedlings with two-photon microscopy in combination with a classical staining technique. Our results showed a significant increase in the average haustorium size 22, 44, 68, 92 and 116 h after inoculation (hai). After 116 hai no significant change was observed until 336 hai....
