Effect of Temperature on Expression of Resistance to Meloidogyne spp. In Common Bean (Phaseolus vulgaris)
Abstract:
The effect of soil temperature on the expression of resistance in several common bean lines carrying resistance to root-knot nematodes (Meloidogyne spp.) was studied under controlled temperatures in temperature tank and growth chamber conditions. Resistance to M. javanica and M. incognita race 1 in bean lines A315, A328, A445, G1805, and G2618 was stable at 24-30 C. However, there was a significant increase in reproduction of M. javanica on A315, A328, and A445 when temperature was increased from 26 to 30 C. This increase did not reflect a change from a resistant to a susceptible reaction or classification. Resistance in A315 is derived from G1805, whereas resistance in A328 and A445 is derived from G2618. Alabama No. 1, PI 165426, and PI 165435, with resistance to M. incognita race 2, were heat stressed at temperatures above 27 C. Resistance to M. incognita race 2 in Alabama No. 1 and PI 165435 was lost at 30 C, but PI 165426 supported low reproduction of M. incognita race 2 at all temperatures. Poor root development at 30 C may have been responsible, in part, for the poor development of M. incognita race 2 on PI 165426.

Background and Environment Affect Phenotype
An example of how genetic background affects phenotype can be seen in horses. The Extension gene in horses is responsible for their coat color. A wild-type gene (EE) produces black pigment in the coat, while a mutant gene (ee) produces red pigment. A...

Temperature Dependence on Reaction Rate
Atoms, molecules, or ions must collide before they can react with each other. Atoms must be close together to form chemical bonds. This premise is the basis for a theory that explains many observations regarding chemical kinetics, including factors affecting reaction rates.
The collision theory is based on the postulates that (i) the reaction rate is proportional to the rate of reactant collisions, (ii) the reacting species collide in an orientation allowing contact between...
