A New Pathotype of Puccinia striiformis f. sp. tritici on Wheat in South Africa

Plant Disease, 1999
Following the detection of Puccinia striiformis f. sp. tritici for the first time on wheat (Triticum aestivum) in the Western Cape in August 1996, stripe rust has spread to all the important wheat production areas in South Africa. Only the introduced pathotype (pt. 6E16) was detected in surveys of these areas during 1996 and 1997.

Genome-Wide Identification of the TaBON Gene Family and Its Role in Wheat Pathogen Response

Biology
The BONZAI/BON (copine) gene family encodes evolutionarily conserved proteins that modulate the balance between plant defense responses and growth. However, comprehensive identification and functional exploration of BON members have remained largely ...

Virulence Variations of Puccinia striiformis f. sp. tritici Isolates Collected from Berberis spp. in China

, 2016
The stripe rust pathogen Puccinia striiformis f. sp. tritici frequently causes significant yield losses in China, due to rapid development of new races that overcome resistance in wheat cultivars.

Genome biology and evolution of mating-type loci in four cereal rust fungi.

PLoS Genetics
Permanent heterozygous loci, such as sex- or mating-compatibility regions, often display suppression of recombination and signals of genomic degeneration. In Basidiomycota, two distinct loci confer mating compatibility. These loci encode homeodomain (HD)

Revealing inheritance of a Xinjiang isolate BGTB-1 of Puccinia striiformis f. sp. tritici and the shift of pathogenicity from avirulence to virulence at heterozygous AvrYr5 locus

Journal of Integrative Agriculture
In China, Xinjiang is a relatively independent epidemic region of wheat stripe rust, caused by Puccinia striiformis f. sp. tritici, due to great population genetic divergence of Xinjiang with other inland epidemic regions.

Unveiling the wheat-rust battleground: A transcriptomic journey

Heliyon
The global wheat production faces significant challenges due to major rust-causing fungi, namely Puccinia striiformis f. sp. tritici, P. triticina, and P. graminis f. sp. tritici, responsible for stripe, leaf, and stem rust diseases, respectively.

Assessment of Bread Wheat Genotypes for Resistance to Puccinia striiformis f. sp. tritici

International Journal of Agriculture and Biology
Stripe rust, caused by the fungus Puccinia striiformis f. sp. tritici (Pst), is one of the major diseases that threaten wheat production worldwide. This study aimed to assess the resistance of 100 bread wheat genotypes to stripe rust by multiple evaluations via field testing, seedling stage testing and molecular marker analysis.
