A Putative ABC Transporter Confers Durable Resistance to Multiple Fungal Pathogens in Wheat
It is shown that the LR34 protein resembles adenosine triphosphate–binding cassette transporters of the pleiotropic drug resistance subfamily, which functions in the adult plant and stimulates senescence-like processes in the flag leaf tips and edges. Expand
The emergence of Ug99 races of the stem rust fungus is a threat to world wheat production.
Although new Ug99-resistant varieties that yield more than current popular varieties are being released and promoted, major efforts are required to displace current Ug99 susceptible varieties with varieties that have diverse race-specific or durable resistance and mitigate the Ug99 threat. Expand
Molecular genetic characterization of the Lr34/Yr18 slow rusting resistance gene region in wheat
Wheat expressed sequence tags (wESTs) were identified in a genomic interval predicted to span the Lr34/Yr18 slow rusting region on chromosome 7DS and that corresponded to genes located in theExpand
Gene-specific markers for the wheat gene Lr34/Yr18/Pm38 which confers resistance to multiple fungal pathogens
The locus Lr34/Yr18/Pm38 confers partial and durable resistance against the devastating fungal pathogens leaf rust, stripe rust, and powdery mildew. In previous studies, this broad-spectrumExpand
Current status, likely migration and strategies to mitigate the threat to wheat production from race Ug99 (TTKS) of stem rust pathogen
A Global Rust Initiative has been launched to monitor the further migration of this race, facilitate field testing in Kenya or Ethiopia of wheat cultivars and germplasm developed by wheat breeding programmes worldwide, understand the genetic basis of resistanceespecially the durable type, carry out targeted breeding to incorporate diverse resistance genes into key cultivar and Germplasm, and enhance the capacity of national programmes.

Will stem rust destroy the world's wheat crop?
The proposed strategy is to deploy spring wheat varieties possessing durable, adult plant resistance in East Africa and other primary risk areas to reduce inoculum and selection of new virulences capable of overcoming undefeated race-specific resistance genes. Expand
Microsatellite markers for genes lr34/yr18 and other quantitative trait Loci for leaf rust and stripe rust resistance in bread wheat.
There is significant diversity for genes that have minor effects on stripe rust resistance, and that successful detection of these QTLs by molecular markers should be helpful both for characterizing wheat genotypes effectively and combining such resistance genes. Expand
Lr46: a gene conferring slow-rusting resistance to leaf rust in wheat.
Backcross-derived cytogenetic populations were developed by crossing 'Pavon 76' with a monosomic series of adult-plant leaf rust-susceptible cultivar Lal-bahadur, and one slow-rusting gene was located in chromosome 1B of 'PAvon 76', designated as Lr46. Expand
Global status of wheat leaf rust caused by Puccinia triticina
The importance of leaf rust in the main wheat production areas as reflected by yield losses, the complexity of virulence variation in pathogen populations, the role cultivars with race-specific resistance play in pathogenic evolution, and the control measures currently practiced in various regions of the world are summarized. Expand
Quantitative trait loci of stripe rust resistance in wheat
This review utilizes consensus maps to illustrate important genomic regions that have had effects against stripe rust in wheat, and although this methodology cannot distinguish alleles from closely linked genes, it does highlight the extent of genetic diversity for this trait. Expand
