Wheat defense genes in fungal (Puccinia striiformis) infection

Functional & Integrative Genomics, 2010
Wheat stripe rust, caused by Puccinia striiformis f. sp. tritici, is one of the most important diseases of wheat worldwide. To isolate defense-related genes against the pathogen, a suppression subtractive hybridization library was constructed for an incompatible interaction.

Aggressiveness of Puccinia striiformis isolates on wheat cultivars

Transactions of the British Mycological Society, 1974
Measurements of the aggressiveness of isolates of race 104 E 137 of Puccinia striiformis have been made after point inoculations onto wheat leaves. Significant differences in aggressiveness between isolates have been found using seedling, juvenile and adult plants of the cultivar Joss Cambier.

Atmospheric Ions and Germination of Uredospores of Puccinia striiformis

Science, 1967
Atmospheric ions, identified by mobility characteristics, were associated with germination of lyophilized uredospores of Puccinia striiformis West. at Bozeman Montana. Ions of intermediate size were highest in concentration, and percentage germination of spores was lowest during periods conducive to air pollution ...

Discovery of multiple IGS haplotypes within genotypes of Puccinia striiformis

Fungal Biology, 2012
In a search for specific molecular markers for population analysis of Puccinia striiformis f. sp. tritici, the ribosomal DNA (rDNA) intergenic spacer (IGS) 1 region (rDNA-IGS1, between the 28S and the 5S rDNA genes) was amplified, cloned, and sequenced. It was found to exhibit multiple bands and length polymorphism.

Morphology of infection structures of puccinia striiformis var. dactylidis

Netherlands Journal of Plant Pathology, 1989
The yellow rust fungusPuccinia striiformis var.dactylidis of cocksfoot differs clearly in the morphology of infection structures from both the nominate form, var.striiformis of wheat, barley andElymus and var.striiformis f. sp.poae affectingPoa pratensis. The observations are in accordance with the idea that var.dactylidis and var.striiformis f.sp.poae

A TECHNIQUE FOR GERMINATING UREDOSPORES OF PUCCINIA STRIIFORMIS

1963
Abstract : A technique for germinating uredospores of Puccinia striiformis on a modified commerial one per cent agar is described. The agar is subjected to an intensive washing procedure. With the washed agar, and with germination plates rinsed in a solution of hydrochloric acid, high germination percentages are obtained.

Microsatellite characterisation of South AfricanPuccinia striiformisraces

South African Journal of Plant and Soil, 2016
Since the first appearance of wheat stripe rust in 1996 in South Africa, four Puccinia striiformis races have been described. The first detected race, 6E16A−, was proposed to be a foreign introduction from Central or Western Asia that subsequently gained additional virulence through step-wise mutations.

Genetic and molecular analyses of resistance to a variant of Puccinia striiformis in barley

Journal of Applied Genetics, 2012
Seedlings of 62 Australian barley cultivars and two exotic barley genotypes were assessed for resistance to a variant of Puccinia striiformis, referred to as "Barley Grass Stripe Rust" (BGYR), first detected in Australia in 1998, which is capable of infecting wild Hordeum species and some genotypes of cultivated barley. Fifty-three out of 62 cultivated

COLORED MUTANTS OF PUCCINIA STRIIFORMIS WEST

1963
Abstract : Colored mutants of puccinia striiformis were studied from natural mutation of fungi that produced white pustules rather than the normal orange pustules. the mutant morphology, infective characteristics, germination and color were observed in the many host passages.
