Mapping of quantitative adult plant field resistance to leaf rust and stripe rust in two European winter wheat populations reveals co-location of three QTL conferring resistance to both rust pathogens [PDF]

Theoretical and Applied Genetics, 2014
Key message We detected several, most likely novel QTL for adult plant resistance to rusts. Notably three QTL improved resistance to leaf rust and stripe rust simultaneously indicating broad spectrum resistance QTL.

The Underexplored Mechanisms of Wheat Resistance to Leaf Rust

Plants, 2023
Wheat leaf rust, caused by the obligate biotrophic fungus Puccinia triticina Eriks. (Pt), is one of the most common wheat foliar diseases that continuously threatens global wheat production. Currently, the approaches used to mitigate pathogen infestation

Comparison of Bread Wheat Genotypes for Leaf Rust Resistance Genes

Journal of Agricultural Sciences, 2020
Leaf rust caused by Pucinia recondita tritici is one of the most important diseases of bread wheat worldwide. It is considered that the most environmentally sound; low cost method of controlling leaf rust is to breed and grow genetically resistant wheat ...

Identification of Leaf Rust Resistance Genes in Wheat Cultivars Produced in Kazakhstan [PDF]

Theoretical and Applied Genetics, 2016
Leaf rust, caused by Puccinia recondita f. sp. tritici, is one of the major diseases of wheat in Kazakhstan. To effectively use leaf rust resistance genes (Lr), it is important for breeders to know the resistance genotype in current cultivars.

Autoinfection in wheat leaf rust epidemics [PDF]

New Phytologist, 2008
Autoinfection (within-host inoculum transmission) allows plant pathogens locally to increase their density on an infected host. Estimating autoinfection is of particular importance in understanding epidemic development in host mixtures. More generally, autoinfection influences the rate of host colonization by the pathogen, as well as pathogen evolution.

Genetics of Leaf Rust Resistance in Brambling Wheat [PDF]

Plant Disease, 2008
The CIMMYT-developed spring wheat ‘Brambling’ has a high level of adult-plant resistance (APR) to leaf rust caused by Puccinia triticina. Our objectives were to determine the genetic basis of resistance in seedlings and adult plants and the magnitude of genotype × environment effects on the expression of APR.

Wheat leaf rust caused by Puccinia triticina [PDF]

Molecular Plant Pathology, 2008
SUMMARY Leaf rust, caused by Puccinia triticina , is the most common rust disease of wheat. The fungus is an obligate parasite capable of producing infectious urediniospores as long as infected leaf tissue remains alive.

Physical Mapping of a Novel Locus Conferring Leaf Rust Resistance on the Long Arm of Agropyron cristatum Chromosome 2P

Frontiers in Plant Science, 2018
Wheat leaf rust is one of the most common wheat diseases worldwide and can cause up to 40% wheat yield loss. To combat the growth and spread of leaf rust disease, continual exploration and identification of new and effective resistance genes are needed ...

An Update on Resistance Genes and Their Use in the Development of Leaf Rust Resistant Cultivars in Wheat

Frontiers in Genetics, 2022
Wheat is one of the most important cereal crops in the world. The production and productivity of wheat is adversely affected by several diseases including leaf rust, which can cause yield losses, sometimes approaching >50%. In the present mini-review,

Seedling and Slow Rusting Resistance to Leaf Rust in Chinese Wheat Cultivars [PDF]

Plant Disease, 2010
Identification of resistance genes is important for developing leaf rust resistant wheat (Triticum aestivum) cultivars. A total of 102 Chinese winter wheat cultivars and advanced lines were inoculated with 24 pathotypes of Puccinia triticina for postulation of leaf rust resistance genes effective at the seedling stage.
