Relative DNA Content and Chromosomal Relationships of some Meloidogyne, Heterodera, and Meloidodera spp. (Nematoda: Heteroderidae).
The relative DNA content of hypodermal nuclei of preparasitic, 2nd-stage larvae was determined cytophotometrically in 19 populations belonging to 13 species of Meloidogyne, Heterodera and Meloidodera. In Meloidogyne hapla, M. arenaria, M. incognita and M. javanica, total DNA content per nucleus is proportional to their chromosome number, indicating that chromosomal forms with high chromosome nu...
متن کاملOccurrence of Meloidogyne spp. in Argentina.
A record of 84 plant species in 32 families that are hosts to the root-knot nematode species found in Argentina is presented. The genus Meloidogyne appears to be widely distributed in the country, with Meloidogyne incognita and M. javanica the most frequently detected species. Other species found in Argentina include M. arenaria, M. cruciani, M. decalineata, M. hapla, and M. ottersoni. The pres...
متن کاملMolecular polymorphism and phylogenetic relationship in some Meloidogyne spp.: application to the taxonomy of Meloidogyne.
Proteins and various isozymes were investigated by direct analysis of single specimens in order to check molecular genetic variability, which is not rare in Meloidogyne species in spite of parthenogenetic reproduction. Variability was found in esterases, ocglycerophosphate, malate dehydrogenases, and some other proteins. Other loci appear monomorphic in the genus (for example, catalase), Distin...
متن کاملReproduction of Mi-Virulent Meloidogyne incognita Isolates on Lycopersicon spp.
Selection of detectable numbers of Mi-virulent root-knot nematodes has necessitated a greater understanding of nematode responses to new sources of resistance. During the course of this research, we compared the reproduction of four geographically distinct Mi-virulent root-knot nematode isolates on three resistant accessions of Lycopersicon peruvianum. Each accession carried a different resista...
متن کاملIdentification of field populations of Meloidogyne spp. by chromosome number.
Identification of species of Meloidogyne Goeldi, 1887 is fi-equently accomplished by using perineal patterns and morphometrics, but intraspecific populations are not easily distinguished. Chromosome numbers have been determined for 10 (6) of the 36 species of Meloidogyne which are currently recognized (1, 5). Four of these species have a range of chromosome numbers. This chromosome range permit...
