Dasypyrum villosum Candargy (syn. Haynaldia villosa) is a cross-pollinating, diploid (2n = 2x = 14) annual species that belongs to the tribe Triticeae (18). It is native to Southern Europe and West Asia, especially the Caucasuses (14), and grows under conditions unfavorable to most cultivated crops. The genome of D. villosum, designated V by Sears (40), is considered an important donor of genes...

Thomas, J. B., Conner, R. L. and Graf, R. J. 2012. Radiant hard red winter wheat. Can. J. Plant Sci. 92: 169 175. Radiant hard red winter wheat (Triticum aestivum L.) is well adapted to the non-hazard region for stem rust (Puccinia graminis Pers.: Pers. f. sp. tritici Eriks. & E. Henn.) within the Canadian prairies. Based on evaluation relative to Norstar, CDC Osprey, AC Tempest and AC Bellatri...

Stripe rust, caused by Puccinia striiformis f. sp. tritici, is a devastating disease of wheat in Turkey and worldwide. This pathogen can overcome known resistance genes negatively affect the production. The objectives this study were to determine virulence patterns stripe rust isolates collected from coastal areas (Aegean Mediterranean regions) Turkey, examine genetic diversity populations simp...

wheat is grown on 6.2 million hectares under different agr-climate conditions in iran. of 6.2 million hectares irrigated wheat, khazar warm humid climate regions (gorgan, mazandaran and moghan) with 350 thousand hectares are the most important wheat growing areas of the country. productive and rich lands, high rainfalls and favorable temperature and light in these regions provide good condition...

In this study, we successfully introgressed and validated Yr59 into four elite wheat cultivars, Jimai 22, Chuanmai 42, Zhengmai 9023 Xinmai 26 through marker-assisted backcross selection. Used as female parents, these cultivars were crossed with line PI 660061 (Yr59). After two backcrosses selection, the progenies selfed advanced to BC2F4 generation. A total of 123 lines selected based on agron...

The wheat stripe rust fungus, Puccinia striiformis f. sp. tritici (Pst), does not have a known alternate host for sexual reproduction, which makes it impossible to study gene linkages through classic genetic and molecular mapping approaches. In this study, we compared 4,219 Pst expression sequence tags (ESTs) to the genomic sequence of P. graminis f. sp. tritici (Pgt), the wheat stem rust fungu...

to evaluate the reaction of some wheat advanced lines and cultivars to yellow rust at seedling stage, seeds of 200 accessions were planted in 5cm diameter pots (4-6 seeds per pot) in greenhouse. the seedlings were inoculated with fresh harvested urediniospores of two different races of puccinia striiformis f.sp. tritici (134e134a+ from karaj and 134e142a+ from maragheh, iran) when the first see...

BACKGROUND Respiratory infections with sputum production are a major reason for physician visits, diagnostic testing, and antibiotic prescription in the United States. We sought to determine whether the simple characteristic of sputum color provides information that impacts resource utilization such as laboratory testing and prescription of antibiotics. METHODS Out-patient sputum samples subm...

Abstract Stripe rust, caused by Puccinia striiformis f. sp. tritici , is one of the most devastating diseases wheat worldwide. This study dealt with investigating biocontrol activity mycorrhizal colonization and/or application Streptomyces viridosporus HH1 against stripe rust wheat. In vitro, data showed that S. had a strong anti-spore germination effect on uredospores P. (90% reduction) . A 84...
