A Multiplex Real-Time Polymerase Chain Reaction (TaqMan) Assay for the Simultaneous Detection of Meloidogyne chitwoodi and M. fallax.
ABSTRACT This study describes a multiplex real-time polymerase chain reaction (PCR) approach for the simultaneous detection of Meloidogyne chitwoodi and M. fallax in a single assay. The approach uses three fluorogenic minor groove binding (MGB) TaqMan probes: one FAM-labeled to detect M. chitwoodi, one VIC-labeled to detect M. fallax, and one NED-labeled to detect the internal amplification con...
متن کاملResistance in Triticum and Aegilops spp. to Meloidogyne chitwoodi.
Two lines of Aegilops squarrosa (G 3489 and G 1279) and Triticum cultivars Anza, Cocorit, Produra, Chinese Spring, Nugaines, and a synthetic hexaploid were screened for resistance to Meloidogyne chitwoodi. Reproduction of M. chitwoodi, expressed as eggs per gram root, was low (P < 0.01) on G 3489 and the synthetic hexaploid. Reproduction on all other cultivars tested was high although differenc...
متن کاملInfluence of Meloidogyne chitwoodi and M. hapla on Wheat Growth.
Meloidogyne chitwoodi reduced the growth of winter wheat 'Nugaines' directly in relation to nematode density in the greenhouse, The relationship between top dry weight and initial nematode density suggests a tolerance limit of Nugaines wheat to M. chitwoodi of between 0.03 and 0.18 eggs/cm(3) of soil; the value for relative minimum plant top weight was 0.45 g and 0.75 g, respectively. Growth of...
متن کاملRelationship of Resistance to Meloidogyne chitwoodi (race 2) and M. hapla in Alfalfa.
In the Pacific Northwest, alfalfa (Medicago sativa) is host to two species of root-knot nematodes, including race 2 of the Columbia root-knot nematode (Meloidogyne chitwoodi) and the northern root-knot nematode (Meloidogyne hapla). In addition to the damage caused to alfalfa itself by M. hapla, alfalfa's host status to both species leaves large numbers of nematodes available to damage rotation ...
متن کاملA new AluI satellite DNA in the root-knot nematode Meloidogyne fallax: relationships with satellites from the sympatric species M. hapla and M. chitwoodi.
A highly abundant satellite DNA comprising 20% of the Meloidogyne fallax (Nematoda, Tylenchida) genome was cloned and sequenced. The satellite monomer is 173 bp long and has a high A + T content of 72.3%, with frequent runs of A's and T's. The sequence variability of the monomers is 2.7%, mainly due to random distribution of single-point mutations. A search for evidence of internal repeated sub...
