Reproduction of the root-knot nematode Meloidogyne arenaria on flue-cured tobacco possessing resistance genes Rk1 and/or Rk2 and the impact of parasitism on the accumulation of nicotine in conventional and low-alkaloid tobacco
… gene also provides resistance to race 1 of M. arenaria. The widespread deployment of this resistance has fostered a shift in root-knot nematode population dynamics, as a result of which M. arenaria race 2 has become the predominant root-knot nematode threat in Virginia. A second resistance gene …

Effects of Increased Atmospheric Carbon Dioxide Levels on Tobacco Mosaic Virus and Root-Knot Nematodes in Genetically Resistant and Susceptible Tomato Plants
… CO<sub>2</sub> on Root-Knot Nematode (<em>Meloidogyne arenaria</em>) and Tobacco Mosaic Virus (TMV) infection in genetically resistant versus susceptible tomatoes (<em>Solanum lycopersicum</em>). Both resistant and susceptible tomatoes were grown in chambers with either ambient …

Reproduction of a root-knot nematode population on flue-cured tobacco homozygous for Rk1 and/or Rk2 resistance genes and the effect of soil temperature on resistance gene efficacy
… gene, providing resistance to races 1 and 3 of Meloidogyne incognita and race 1 of M. arenaria. This initiated a shift in root-knot populations to other species and races, creating a need for resistance to those populations. Numerous cultivars possess a second resistance gene, Rk2. Greenhouse …
