race-specific resistance of wheat to yellow rust caused by puccinia striiformis f. sp. tritici has been reported as short-lived. partial resistance, a kind of quantitative resistance, has been reported to be more stable. partial resistance in terms of slow rusting parameters including final rust severity (frs), apparent infection rate (r), relative area under disease progress curve (raudpc), an...

A study was conducted to assess the durable resistance in a near isogenic line of spring wheat (Triticum aestivalis L.), possessing resistance gene Yr-18 to some isolates (race specific resistance) of stripe rust (Puccinia striiformis f. sp. tritici), namely Thatcher Yr-18 and durable resistance of an cultivar of spring wheat to all isolates of stripe rust (race non- specific resistance), namel...

Although quantitative resistance loci provide partial and durable resistance to a range of pathogen species in different crops, the molecular mechanism of quantitative disease resistance has remained largely unknown. Recent advances in characterization of the genes contributing to quantitative disease resistance and plant-pathogen interactions at the molecular level provide clues to the molecul...

Quantitative resistance has gained interest in plant breeding for pathogen control in low-input cropping systems. Although quantitative resistance frequently has only a partial effect and is difficult to select, it is considered more durable than major resistance (R) genes. With the exponential development of molecular markers over the past 20 years, resistance QTL have been more accurately det...

Stripe rust of wheat, caused by Puccinia striiformis f. sp. tritici, continues to cause severe damage worldwide. Durable resistance is necessary for sustainable control of the disease. High-temperature adult-plant (HTAP) resistance, which expresses when the weather becomes warm and plants grow older, has been demonstrated to be durable. We conducted numerous studies to understand the molecular ...

Introduction The potato (Solanum tuberosum) originated from South America and is now the third largest crop in the world, after rice and wheat. Potato is a cross pollinated and vegetatively propagated crop, with a genome size around 840 MB, which was recently sequenced. Most potato cultivars are autotetraploid, with breeding programs lasting for 12–15 years. Among many biotic and abiotic stress...

To engineer plants with increased and durable disease resistance using transgenic technologies we must address two questions. First, what gene or genes do we want to express to improve disease resistance, and second, how are we going to express these genes so that crop yields are actually increased? Emerging technologies are providing us with a plethora of candidate genes that might lead to enh...

Resistance breakdown has been observed following the deployment of plant cultivars resistant to pests. Assessing the durability of a resistance requires long-term experiments at least at a regional scale. We collected such data for melon resistance conferred by the Vat gene cluster to melon aphids. We examined landscape-level populations of Aphis gossypii collected in 2004-2015, from melon-prod...
