Fine mapping of leaf rust resistance gene LrZH84 using expressed sequence tag and sequence-tagged site markers, and allelism with other genes on wheat chromosome 1B
(American Phytopathological Society (APS), 2013)
Zhou 8425B, possessing the leaf rust resistance gene LrZH84, is an elite wheat (Triticum aestivum) parental line in the Yellow-Huai Valley region of China. In the present study, 2,086 F2 plants derived from Zhou 8425B/Chinese ...

Association mapping of North American spring wheat breeding germplasm reveals loci conferring resistance to Ug99 and other African stem rust races
(BioMed Central, 2015)
Background: The recently identified Puccinia graminis f. sp. tritici (Pgt) race TTKSK (Ug99) poses a severe threat to global wheat production because of its broad virulence on several widely deployed resistance genes. ...

Harnessing diversity in wheat to enhance grain yield, climate resilience, disease and insect pest resistance and nutrition through conventional and modern breeding approaches
(Frontiers, 2016)
Current trends in population growth and consumption patterns continue to increase the demand for wheat, a key cereal for global food security. Further, multiple abiotic challenges due to climate change and evolving pathogen ...

Enhanced resistance in wheat against stem rust achieved by marker assisted backcrossing involving three independent Sr genes
(Elsevier, 2015)
Marker assisted backcrossing (MABC) was used to transfer the three stem rust (Puccinia graminis tritici)resistant genes Sr25, SrWeb and Sr50 into the popular Indian wheat cv. HUW234. The donor was theCIMMYT breeding line ...

A high density GBS map of bread wheat and its application for dissecting complex disease resistance traits
(BioMed Central, 2015)
Genotyping-by-sequencing (GBS) is a high-throughput genotyping approach that is starting to be used in several crop species, including bread wheat. Anchoring GBS tags on chromosomes is an important step towards utilizing ...

Identification and validation of a common stem rust resistance locus in two bi-parental populations
(Frontiers, 2018)
Races belonging to Ug99 lineage of stem rust fungus Puccinia graminis f. sp. tritici (Pgt) continue to pose a threat to wheat (Triticum aestivum L.) production in various African countries. Growing resistant varieties is ...
Article
Yellow Rust epidemics worldwide were caused by Pathogen Races from divergent genetic lineages
(Frontiers, 2017)
We investigated whether the recent worldwide epidemics of wheat yellow rust were driven by races of few clonal lineage(s) or populations of divergent races. Race phenotyping of 887 genetically diverse Puccinia striiformis ...
Article
Nested association mapping of stem rust resistance in wheat using genotyping by sequencing
(Public Library of Science, 2016)
We combined the recently developed genotyping by sequencing (GBS) method with joint mapping (also known as nested association mapping) to dissect and understand the genetic architecture controlling stem rust resistance in ...

Natural variation in elicitation of defense-signaling associates to field resistance against the spot blotch disease in bread wheat (Triticum aestivum L.)
(Frontiers, 2018)
Spot blotch, caused by the hemibiotropic fungus Bipolaris sorokiniana, is amongst the most damaging diseases of wheat. Still, natural variation in expression of biochemical traits that determine field resistance to spot ...
