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 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 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...
متن کاملImportance of Temperature in the Pathology of Meloidogyne hapla and M. chitwoodi on Legumes.
Effects of temperatures on the host-parasite relationships were studied for three legume species and four populations of root-knot nematodes from the western United States. The nematode populations were Meloidogyne hapla from California (MHCA), Utah (MHUT), and Wyoming (MHWY), and a population of M. chitwoodi from Utah (MCUT). The legumes were milkvetch (Astragalus cicer), alfalfa (Medicago sat...
متن کاملComparative Relationship between Meloidogyne chitwoodi and M. hapla population Densities and Growth of Sugarbeet Seedlings.
ever, this may merely be a reflection of the extent to which the cuticle has been reabsorbed at the t ime of fixation since the cuticles of all these Lts are part ial ly reabsorbed dur ing moult ing. Also, the cuticle of the L~ of O. phyllobia appears to be structurally more complex than that of A. agrostis since it has a distinct striated basal layer (Fig. 1A, D) which is reabsorbed at a later...
