摘要: The genetic and molecular tools available in Arabidopsis allow identification of insect resistance genes. Many functional aspects pest recognition signal transduction are conserved the defensive physiology a broad range plant species. Therefore, studies may be extended to genomics many species agricultural ecological importance. Because public concerns for field release genetically modified organisms, naturally occurring variation herbivores will valuable breeding. Combined employing QTL mapping candidate genes necessary find understand responsible resistance. We review experiments showing that populations contain high levels disease resistance, this can manipulated alter its components predictable fashion. In Arabidopsis, we map controlling physiological variation, estimate importance regulatory or enzyme-encoding loci. Finally, approaches Arabidopsis.
