Quantitative Resistance to Plant Pathogens in Pyramiding Strategies for Durable Crop Protection
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...
متن کاملTowards Durable Resistance by Stacking Broad Spectrum Cisgenic Resistance Genes
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...
متن کاملExploiting pathogens' tricks of the trade for engineering of plant disease resistance: challenges and opportunities
With expansion of our understanding of pathogen effector strategies and the multiplicity of their host targets, it is becoming evident that novel approaches to engineering broad-spectrum resistance need to be deployed. The increasing availability of high temporal gene expression data of a range of plant-microbe interactions enables the judicious choices of promoters to fine-tune timing and magn...
متن کاملGenes from mycoparasitic fungi as a source for improving plant resistance to fungal pathogens.
Disease resistance in transgenic plants has been improved, for the first time, by the insertion of a gene from a biocontrol fungus. The gene encoding a strongly antifungal endochitinase from the mycoparasitic fungus Trichoderma harzianum was transferred to tobacco and potato. High expression levels of the fungal gene were obtained in different plant tissues, which had no visible effect on plant...
متن کاملPlant Resistance Genes for Fungal Pathogens - Physiological Models and Identification in Cereal Crops
The complex biological phenomenon “resistance” can be reduced to single Mendelian traits acting on both the plant and the pathogen side in a number o f pathosystems. According to the “gene-for-gene hypothesis”, the outcome o f a plant/pathogen interaction in these cases is in compatibility if a plant carrying a particular resistance gene and a pathogen with the comple mentary avirulence gene ...
