Abstract


Soil samples collected from the rhizosphere of coconut palms and Coccoloba uvifera shrubs on the beach of Cuyagua on the Caribbean sea in northern Venezuela contained specimens of Longidorus edmundsi Hunt et Siddiqi, 1977. The Venezuelan population of L. edmundsi is biometrically smaller than the type population with the lip region slightly expanded compared with the original specimens in which it is continuous with the rest of the body. Isoelectrofocusing of SOD isoforms showed three main bands with highest SOD activity at pH 6.9. The PCR products of the ITS region was about 2.2 Kb and was digested by ten restriction enzymes but not by Mva I.
