Cell wall modifications induced by plant parasitic nematodes and Biocontrol
Summary:
Root knot nematodes of the species Meloidogyne incognita are obligatorily parasitic organisms that infect the roots of many cultivated plants. They induce the differentiation of the parenchymatic cells of the central cylinder to giant-cells from which they feed until they complete their life cycle. Nematode entry in the root of the plant causes a line of responses, which include also the change in the composition of the cell walls, via the expression of various genes. In the Arabidopsis thaliana L. fra2 mutant, katanin, that contributes in the proper microtubule organization and consequently regulates indirectly the configuration of the cell wall, is not functional. In order to study the contribution of microtubules in the root knot infection, fra2 cell wall composition was estimated by immunolabbeling as well as the sensitivity of the mutant against root knot nematode infection. Biocontrol experiments were performed using indigenous Streptomyces strains from ATHUBA to prevent nematode infection.
