PETEIRA, Belkis et al. INDUCTION OF EXTRACELLULAR ENZYMES WITH Meloidogyne incognita AND Globodera pallida EGGS. Rev. Protección Veg. [online]. 2009, vol.24, n.2, pp.94-101. ISSN 1010-2752.

The Cuban strain IMI SD 187 of the nematophagous fungus Pochonia chlamydosporia var. catenulata is a potential biological control agent for the root knot nematodes. There are reports about the controlling action of these fungi on cyst nematodes. However, isolate specificity according to the original host is also known. The aim of this work was to study the enzymatic performance induced by Meloidogyne incognita and Globodera pallida eggs. The induction assays were carried out in liquid media. The total protein content and the enzymatic activity levels for proteases, chitinases, lipases and VCP 1 were determined. The time course experiment for enzymatic activity induction was related to the infection process of M. incognita eggs by the strain IMI SD 187. The strain IMI SD 187 of P. chlamydosporia var. catenulata isolated from root knot nematodes is able to infect eggs from cyst nematodes.

Keywords : Pochonia chlamydosporia var. catenulata; enzymatic activity; Meloidogyne incognita; Globodera pallida.
