Abstract
The nucleotide sequence of a 992 bp region of cDNA and the nucleotide sequence of a 1973 bp (or a 1913 bp) of genomic DNA of the Gr-cm-1 gene were determined for G. rostochiensis. PCR primers and probes specific for G. rostochiensis and G. pallida were generated. PCR assays, including a real-time TaqMan PCR were used to identify G. rostochiensis and G. pallida and to differentiate G. rostochiensis from G. pallida. Transgenic hairy roots expressing Gr-cm-1 dsRNA were generated. There was a 52% reduction in the average number of females per root in the Gr-cm-1 dsRNA transgenic lines when compared with the infected control lines.
Claims9
An isolated polynucleotide consisting of at least 50 contiguous nucleotides of a portion of SEQ ID NO:
- 4, said portion starting at nucleotide position 58 and ending at nucleotide position 757, wherein uptake by a G. rostochiensis nematode of a dsRNA sequence comprising at least one strand that is complementary to said isolated polynucleotide inhibits the growth of said nematode.
