ABSTRACT Stripe rust is one of the most important diseases of wheat and barley worldwide. On wheat it is caused by Puccinia striiformis f. sp. tritici and on barley by P. striiformis f. sp. hordei Most wheat genotypes are resistant to P. striiformis f. sp. hordei and most barley genotypes are resistant to P. striiformis f. sp. tritici. To determine the genetics of resistance in wheat to P. stri...
The wheat powdery mildew resistance gene Pm40, which is located on chromosomal arm 7BS, is effective against nearly all prevalent races of Blumeria graminis f. sp tritici (Bgt) in China and is carried by the common wheat germplasm PI 672538. A set of the F1, F2 and F2:3 populations from the cross of the resistant PI 672538 with the susceptible line L1034 were used to conduct genetic analysis of...
Systemic acquired resistance (SAR) is one of the intriguing issues for studying the mechanism in signal transduction system in a whole plant. We found that SAR and increase of an antifungal compound were induced rapidly and transiently in barley (Hordeum vulgare L. cv. Goseshikoku) by mechanical and biological stresses. One of the major antifungal compounds was identified as an indole alkaloid,...
In plants, disease resistance mediated by the gene-for-gene mechanism involves the recognition of specific effector molecules produced by the pathogen either directly or indirectly by the resistance-gene products. This recognition triggers a series of signals, thereby serving as a molecular switch in regulating defense mechanisms by the plants. To understand the mechanism of action of the barle...
Zestaw 478 linii jęczmienia (Hordeum vulgare L.) był badany pod kątem odporności na mączniaka prawdziwego. Badane linie wyprowadzono z odmian miejscowych jarego pochodzących głównie Basenu Morza Śródziemnego. W badaniach wykorzystano trzy izolaty Blumeria graminis o znanym profilu wirulencji. Ocenę wykonano siewkach w warunkach kontrolowanych. Badanie pozwoliło wyselekcjonować 111 odpornych jęc...
Lesion mimics (LMs) that exhibit spontaneous disease-like lesions in the absence of pathogen attack might confer enhanced plant disease resistance to a wide range of pathogens. The LM mutant, lm3 was derived from a single naturally mutated individual in the F1 population of a 3-1/Jing411 cross, backcrossed six times with 3-1 as the recurrent parent and subsequently self-pollinated twice. The le...
