the 1rs chromosome segment derived from petkus rye carries genes for resistance to three wheat rust diseases, namely lr26 for resistance to leaf rust (caused by puccinia triticina), yr9 for resistance to stripe rust (p.striiformis f. sp. tritici) and sr31 for resistance to stem rust (p. graminis f. sp. tritici). since sec-1 is tightly linked with the three rust resis-tance genes electrophoresis...

The transfer of agronomically useful genes from wild wheat species into cultivated wheat is one of the most effective approaches to improvement of wheat varieties. To evaluate the transfer of genes from Dasypyrum villosum into Triticum aestivum, wheat quality and disease resistance was evaluated in two new translocation lines, T1DL•1V#3S and T1DS•1V#3L. We examined the levels of stripe rust res...

Stripe rust is a devastating fungal disease that afflicts wheat in many regions of the world. New races of Puccinia striiformis, the pathogen responsible for this disease, have overcome most of the known race-specific resistance genes. We report the map-based cloning of the gene Yr36 (WKS1), which confers resistance to a broad spectrum of stripe rust races at relatively high temperatures (25 de...

in this study, isolate sr99-ua (race 70e 128) of wheat stripe rust (puccinia striiformis west. f. sp. tritici eriks) was used to infect susceptible spring wheat (cultivar thatcher) and its near isogenic line possessing yr-18 adult-plant resistance gene. samples were taken at the flag leaf stage and observed using light, transmission and scanning electron micro-scopes. no major differences in th...

confocal laser scanning microscopy (clsm) is a revolutionary advance in the field of light microscopy which, in recent years, has been used on interaction studies between host and pathogen. this study carried out on the flag leaves of the susceptible spring wheat cultivar (triticum aestivum l.) known as thatcher and its near isogenic line with the yr-18 adult-plant resistance gene to stripe rus...

Stripe rust or yellow rust (YR), caused by Puccinia striiformis f. sp. tritici (Pst), is one of the most important diseases of wheat (Triticum aestivum L.). Widespread deployment of resistant cultivars is the best means of achieving durable disease control. The red grain, spring wheat cultivar Napo 63 produced by CIMMYT in the 1960s shows a high level of adult-plant resistance to stripe rust in...

Stripe rust, caused by Puccinia striiformis Westend. f. sp. tritici Erikss. (Pst) remains one of the most significant diseases of wheat worldwide. We investigated stripe rust resistance by genome-wide association analysis (GWAS) in 959 spring wheat accessions from the United States Department of Agriculture-Agricultural Research Service National Small Grains Collection, representing major globa...

Journal of Plant Registrations, Vol. 3, No. 3, September 2009 279 Stripe rust (Puccinia striiformis Westend f. sp. tritici) is a major disease threat of spring wheat (Triticum aestivum L.) grown in the Pacifi c Northwest region of the United States. Few soft white spring wheat cultivars currently in commercial production have adequate levels of stripe rust resistance to prevent the need for fun...

Glyphosate is a broad-spectrum herbicide used for the control of weeds in glyphosate-resistant crops. Glyphosate inhibits 5-enolpyruvyl shikimate 3-phosphate synthase, a key enzyme in the synthesis of aromatic amino acids in plants, fungi, and bacteria. Studies with glyphosate-resistant wheat have shown that glyphosate provided both preventive and curative activities against Puccinia striiformi...

Fungal diseases, especially leaf and stripe rusts are wheat yield reducing factors in Iran and the world. In this study, genetic diversity of 20 wheat varieties with different response to leaf and stripe rusts were studied using primers designed based on the conserved regions of plant disease resistance genes. The banding patterns of polymorphic markers were scored as dominant and number of amp...
