Abstract

The four synaptonemal complexes (SC) in Meloidogyne nataliei (n=4) have normal, tripartite morphology, although the total width of the SC is only 50 nm. Each SC is attached at both ends to the nuclear envelope and there is no bouquet formation at pachytene. Pairing of homologues is regular but not complete, as there is one region on each bivalent where the SC is not formed. This region may be the ‘fusion point’ of telomeres of nonhomologous chromosomes, since it is assumed that M. nataliei has been derived from an ancestral strain (n=8) via chromosomal fusions. In each pachytene nucleus there is a nonmembranous, vacuole-like structure of unknown function located in the nucleoplasm adjacent to the nucleolus, and of approximately the same volume as the nucleolus. The fact the SC structure of M. nataliei is strikingly different from that of most Meloidogyne species suggest that M. nataliei may not belong to the same phyletic group as the genus Meloidogyne.
