    ABSTRACT: The aims are to establish a polymerase chain reaction (PCR)-based method for detecting Pythium myriotylum in the rhizome of ginger and diagnosing ginger soft rot and screening health seed ginger. A booster PCR method was established for detection of P. myriotylum using a specific primer selected from rDNA ITS1 region coupled with universal primer ITS2. It successfully applied to the detection of P. myriotylum in naturally infected ginger rhizomes but not from DNA of ginger rhizomes collected from field without target fungus. A specific method for detecting P. myriotylum was achieved. The new PCR method has allowed us to monitor ginger for the presence of P. myriotylum as a way of disease diagnosis or healthy seed ginger examination.

    ABSTRACT: Pythium aphanidermatum causes damping-off and root rot of vegetable crops in hydroponic systems. A DNA probe was isolated and modified from a library ofHindIII-digested mitochondrial DNA ofP. aphanidermatum that strongly hybridized to DNA ofP. aphanidermatum and weakly hybridized to DNA ofPythium deliense. Cross-hybridizing sequences were absent from DNA of plants and other related fungi. The probe detected as little as 5 ng ofP. aphanidermatum DNA and 250 ng ofP. deliense DNA in slot-blot assays.P. aphanidermatum was detected by a hybridization assay of total DNA extracted directly from infected roots. A pair of oligonucleotide primers P1 and RP2, which allowed amplification of a specific 0.65 kb DNA fragment ofP. aphanidermatum using polymerase chain reaction (PCR), was designed from a specific DNA probe. Specific amplification of this fragment fromP. aphanidermatum was highly sensitive, detecting template DNA as low as 0.1 pg total DNA by booster PCR. Specific booster PCR amplification using P1 and RP2 was successful in detectingP. aphanidermatum in naturally infected nutrient solution and roots of vegetables in a field hydroponic system.
