Diversity ofPuccinia striiformison Cereals and Grasses

Annual Review of Phytopathology, 2011
Yellow (stripe) rust is a common fungal disease on cereals and grasses. It is caused by Puccinia striiformis sensu lato, which is biotrophic and heteroecious. The pathogen is specialized on the primary host at both species and cultivar levels, whereas several Berberis spp. may serve as alternate hosts.

Wheat-Puccinia striiformis Interactions

2017
Owing to the scientific and economic importance, the antagonistic wheat-Puccinia striiformis f. sp. tritici (Pst) pathosystem has been a focus of research over the past five decades. With the recent discovery of barberry as alternate hosts, Pst has been confirmed to be heteroecious, and the roles of the alternate hosts in disease epidemiology and ...

Race Typing of Puccinia striiformis on Wheat

2017
A procedure for virulence phenotyping of isolates of yellow (stripe) rust using spray inoculation of wheat seedlings by spores suspended in an engineered fluid, Novec™ 7100, is presented. Differential sets consisting of near-isogenic Avocet lines, selected lines from the "World" and "European" sets, and additional varieties showing race-specificity ...

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.

Monoclonal antibodies for the detection of Puccinia striiformis urediniospores

Mycological Research, 2007
The fungal pathogen Pst causes yellow rust disease in wheat plants leading to crop losses. The organism spreads by releasing wind-dispersed urediniospores from infected plants. In this study a library of novel monoclonal antibodies (mAbs) was developed against Pst urediniospores.

Assessment of Aggressiveness of Puccinia striiformis on Wheat

2017
A simple point-inoculation method using Novec™ 7100, a volatile engineered fluid, is presented for the assessment of aggressiveness of Puccinia striiformis isolates on seedlings of wheat. The method allows for quantification of the applied inoculum with a minimal risk of cross-contamination of rust from leaves grown side by side.

Race 58C of Puccinia striiformis (wheat yellow rust)

Transactions of the British Mycological Society, 1970
Several samples of wheat yellow rust, collected for the Physiologic Race Surveys, were identified as a biotype of race 58 and named race 58C. The reactions of race 58C are compared with those of race 58. The ability of race 58C to infect varieties with certain genes for resistance is discussed indicating that many wheat varieties are seedling ...

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.

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.
