Journal ArticleDOI
Global status of wheat leaf rust caused by Puccinia triticina
Julio Huerta-Espino,Ravi P. Singh,Silvia Germán,Brent McCallum,Robert F. Park,W. Q. Chen,Subhash C. Bhardwaj,Henriette Goyeau +7 more
TL;DR: 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.
Journal ArticleDOI
Leaf rust resistance gene Lr1, isolated from bread wheat (Triticum aestivum L.) is a member of the large psr567 gene family.
Sylvie Cloutier,Brent McCallum,Caroline Loutre,Travis Banks,Thomas Wicker,Catherine Feuillet,Beat Keller,Mark C. Jordan +7 more
TL;DR: Sequence analysis of Lr1 indicated that it is not related to the previously isolated Lr10 and Lr21 genes and unlike these genes, it is part of a large gene family.
Journal ArticleDOI
Host-induced gene silencing of wheat leaf rust fungus Puccinia triticina pathogenicity genes mediated by the Barley stripe mosaic virus
TL;DR: It is demonstrated that BSMV-mediated in planta-generated RNAi is an effective strategy for functional genomics in rust fungi.
Journal ArticleDOI
An introgression on wheat chromosome 4DL in RL6077 (Thatcher*6/PI 250413) confers adult plant resistance to stripe rust and leaf rust (Lr67).
Colin W. Hiebert,J. B. Thomas,Brent McCallum,D. Gavin Humphreys,R. M. DePauw,Matthew J. Hayden,Rohit Mago,Wendelin Schnippenkoetter,Wolfgang Spielmeyer +8 more
TL;DR: The leaf rust resistance gene in RL6077 is phenotypically similar to Lr34 which is located on chromosome 7D, but this gene is not involved in any translocation carried by RL60 77 and has been assigned the name Lr67.
Journal ArticleDOI
Endogenous silencing of Puccinia triticina pathogenicity genes through in planta-expressed sequences leads to the suppression of rust diseases on wheat.
TL;DR: Results show that A. tumefaciens-mediated PITGS can be used as a reverse-genetics tool to discover gene function in rust fungi, and indicates that the targeted fungal transcripts might be important in pathogenesis, and could potentially be used for developing RNA interference-based resistance against rust fungi.
