Znaczniki typów odporności pszenicy na Puccinia triticina

Biuletyn Instytutu Hodowli i Aklimatyzacji Roślin, 2019
Celem pracy było wskazanie różnic pomiędzy odpornością rasowo-specyficzną i rasowo-niespecyficzną, by ocena odporności polowej badanej linii hodowlanej mogła być uzupełniona o dane wskazujące na typ odporności. Materiałem do badań była pszenica podatna odmiany Thatcher (Tc) oraz 5 linii izogenicznych z genami warunkującymi określony, znany typ ...

Physiologic Specialization of Puccinia triticina on Wheat in the United States in 2015 [PDF]

Plant Disease, 2017
Leaves of wheat infected with the leaf rust fungus, Puccinia triticina, were obtained from farm fields and breeding plots at experimental stations in the Great Plains, Ohio River Valley, and southeastern states in 2015 in order to identify virulence phenotypes prevalent in the United States in different wheat growing regions.

Long‐term surveillance reveals hybridization by nuclear reassortment and intercontinental spread as major evolutionary drivers in wheat yellow rust

New Phytologist, Volume 251, Issue 4, Page 2091-2106, August 2026.
Documented incursions of Puccinia striiformis 2009–2023 based on sequential resampling of MLGs/pathogen races on different continents. Summary Evolutionary forces affecting crop pathogens, including hybridization and long‐distance dispersal (LDD), may have strong implications for food security and sustainable plant disease control at global scales ...

Effect of cytoplasm on expression of genes for resistance to Puccinia triticina

Zbornik Matice srpske za prirodne nauke, 2007
The F2 progenies from crosses of wheat varieties Pliska, Sreca, Vila, Holly, three BM lines as Lr 26, Lr 34 and Lr 38 near isogenic lines (NIL), were tested simultaneously in the greenhouse at seedling stage (20?C) and differentiated according to the reaction type to Puccinia triticina monopustule isolate collected from Pesma, the most resistant wide ...

Cytological and Molecular Analysis of the Hordeum vulgare-Puccinia triticina Nonhost Interaction

Molecular Plant-Microbe Interactions, 2003
Cultivated barley, Hordeum vulgare L., is considered to be a nonhost or intermediate host species for the wheat leaf rust fungus Puccinia triticina. Here, we have investigated, at the microscopic and molecular levels, the reaction of barley cultivars to ...

A Meta‐Analysis Reveals That the Protective Role of Silicon in Grasses Against Fungal Pathogens Depends on Infection Mechanism

Plant, Cell &Environment, Volume 49, Issue 8, Page 5947-5964, August 2026.
ABSTRACT Pathogen infection drives plant community structure and constrains global agricultural productivity. Silicon (Si) improves resistance to abiotic and herbivory stress, particularly in grasses, but relatively little attention has addressed Si‐mediated resistance to pathogens, nor has it tested how this varies according to the type of plant and ...

Physiologic Specialization of Puccinia triticina on Wheat in the United States in 2014 [PDF]

Plant Disease, 2016
Collections of Puccinia triticina obtained from wheat fields and breeding plots in the Great Plains, Ohio River Valley, and southeastern states, were tested for virulence in 2014 in order to determine the virulence of the wheat leaf rust pathogen population in the United States.

From Defense Executor to Engineering Target: Harnessing Lignin for Crop Resistance

Advanced Science, Volume 13, Issue 39, 13 July 2026.
Lignin serves as both a physical and chemical executor of broad‐spectrum plant immunity. This review systematically summarizes classical and recent advances in lignin‐mediated immunity, outlines the multifaceted regulatory modules controlling lignification under biotic stress, discusses key physiological and biochemical mechanisms behind lignin‐based ...

Durable resistance to Puccinia triticina by accumulation of resistance genes

Genetika, 2009
The individual use of single race-specific resistance genes with major phenotypic effects has rarely provided lasting resistance. However, breeding and combining or pyramiding of resistance genes into individual cultivars has had considerable success, particularly in situations in which the pathogen does not reproduce sexually, as in the case of wheat ...

A landscape-scale field survey demonstrates the role of wheat volunteers as a local and diversified source of leaf rust inoculum

Scientific Reports, 2023
Deploying disease-resistant cultivars is one of the most effective control strategies to manage crop diseases such as wheat leaf rust, caused by Puccinia triticina. After harvest, this biotrophic fungal pathogen can survive on wheat volunteers present at
