Abstract : Root knot nematode is considered as one of the most important nematode all over the world in Egypt it was found
out that theses nematode attack the root system of most vegetables, fruits and Feld crops causing significance damages and
economic loss .Using the morphological characterization isn't enough for nematode identification to species. So different
molecular technology was used to identify different isolated of these nematode for fast and more accurate results. The
internal transcript spacer (ITS) and restriction fragment length polymorphism (RFLP) of Ribosomal DNA (rDNA) sequences
were used to distinguish between different major species of root knot nematode. DNA fragments containing the internal
transcribed spacer (ITS) rDNA were amplified from DNA genome of different Meloidogyne spp. isolates from different
governorate in Egypt. Ten females were used to amplify PCR product. When primers 5368 and 5367 were used for
amplification of the ITS region, every isolate from the Meloidogyne spp. gave one major product of approximately 760 bp.
When ITS regions of all isolates were digested with restriction enzymes, by using RFLP test (Restriction fragment length
polymorphisms), the size of the DNA fragment using Hind III was strong band at 560 bp and another weak band at 200 bp
that is typical for M. incognita and M. javanica with Hinf I, bands of 440 and 320 pb were obtained while 520, 240 bp bands
were cleared when EcoRl are used. Four bands of 220, 200, 180 and 160 bp were obtained when I restriction enzyme was
used. In multiplex test, a fragment of 415 bp was obtained when M. incognita was used as template (positive control), that
confirming the fact that most nematodes isolates in Egypt are M. incognita
Keywords - Meloidogyne, multiplex, PCR, ribosomal DNA, ITS, RFLP, Scar , restriction enzymes .
