Comparative Disc-Electrophoretic Protein Analyses of Selected Meloidogyne, Ditylenchus, Heterodera and Aphelenchus spp.

D. W. Dickson, J. N. Sasser, D. Huisingh


Disc-electrophoretic separation of soluble proteins from whole nematode homogenates yielded band profiles useful for distinguishing selected species of Meloidogyne and Ditylenchus, and the genera Heterodera, and Aphelenchus. Certain protein bands were common to all the species of Meloidogyne, whereas other bands were specific. Meloidogyne spp. and Heterodera glycines shared some protein similarities, but other genera differed distinctly. Protein profiles of Meloidogyne spp. were not significantly altered by the host on which the nematode was cultured. Key Words: Disc-electrophoresis, Protein composition, chemotaxonomy, Meloidogyne ]avanica, M. incognita, M. arenaria, M. hapla, Ditylenchus dipsaci, D. triformis, Heterodera glycines, Aphelenchus avenae.
