| Abstract: | Root knot nematode is a dangerous disease imposing significant effects on citrus growth and yield in Hunan province. The root knot nematode was collected from infested citrus rhizome in Yongzhou, Hunan province. Based on PCR amplification and morphological observation, the root knot nematode was identified as Meloidogyne panyuensis . According to rDNA ITS sequence alignment, a set of primers was designed to develop a species specific molecular tool for the precise identification of M.panyuensis . The primer reliability, specificity and sensitivity tests showed that the specific PCR was highly sensitive, specific and simple, and could effectively detect M.panyuensis from various root knot nematodes. This specific and rapid PCR detection technology may be a powerful tool for improving taxonomic identification of citrus pathogen nematodes. |
