Stem rust caused by the biotrophic fungal pathogen Puccinia
Interactions between the rust fungus Puccinia
punctiformis and ectophagous and endophagous insects on creeping thistle.
Urediniospore and teliospore morphology were consistent with that described for Puccinia
Virulence dynamics and regional structuring of Puccinia
Twenty-three of the fungi were basidiomycetes, including Puccinia
podophylli [May Apple Rust] and Rhodotuspalmatus [Netted Rhodotus], and 2 fungi were ascomycetes, including Sarcoscypha coccinea [Scarlet Cup] and Galiella rufa [Hairy Rubber Cup].
have shown for the first time that stripe rust, caused by Puccinia
striiformis, is capable of sexually reproducing on the leaves of an alternate host called barberry, a common ornamental.
Kim et al in 2004 showed an antifungal property of the anthraquinones isolated from the Cassia tora against phytopathogenic fungi like Botrytis cineria, Erysiphe graminis, Puccinia
recondite, Pyricularia grisea and the results obtained demonstrated the fungicidal action of emodin, physceion and rhein isolated from Cassia tora by chloroform fractions using chromatographic techniques.
Insect-mediated reproduction of systemic infections by Puccinia
arrhenatheri on Berberis vulgaris.
Dithane will protect against a range of downy mildews, including Peronospora species, rusts including Puccinia
species and leaf spots (Septoria species).
Now, after a 7-year search for suitable biocontrol agent, Murphy's team has settled on the rust fungus Puccinia
spegazzinii, which attacks the weed in its native South and Central America.
This study describes the segregation of genes for resistance to the fungus Puccinia
triticina in a cross between partially resistant wheat CI 13227 and L-574-1.
Pryor says fungal pathogens of cereals fall into two basic classes: nectotrophs, such as the maize blight fungus Helminthosporium, which kill the plant and feast on its dead tissues, and biotrophs such as wheat stem rust, Puccinia
