A comparison of the endogenous cyto kinins in the roots and xylem exudate of nematode resistant and susceptible tomato cultivars



A comparison of the endogenous cyto kinins in the roots and xylem exudate of nematode resistant and susceptible tomato cultivars



Journal of Experimental Botany 28(107): 1351-1356



Non-infested roots of a tomato [Lycoperisicon esculentum] cultivar (Roodeplaat Premier) susceptible to root-knot nematodes contained higher levels of endogenous cytokinins than non-infested roots of a nematode-resistant cultivar (Master F1). In both cultivars nematode [Meloidogyne incognita] infestation increased the cytokinin level in the roots. Sephadex LH-20 fractionation indicated that the xylem exudate of infested susceptible plants ocntained zeatin and zeatin riboside. In the roots of both cultivars a 3rd compound, which co-eluted with zeatin glucoside, was present. The activity of all 3 cell division-inducing compounds was higher in the roots of susceptible plants than in roots of nematode-resistant plants. Cytokinins may be a controlling factor in the development of giant cells.
