穿刺巴斯德芽菌PPh01菌株鉴定及其对根结线虫的寄生性测定
Identification of Strain PPh01 and Its Parasitism Test to Root-knot Nematode
摘要
Abstract
Strain PPh0l, isolated from female root-knot nematode of pepper roots at Ding'an, Hainan Province, was similar to Pasteuria penetrans by morphological characteristics. At the same time, the strain showed the closest 16S rRNA gene sequence similarity to Pasteuria penetrans (99.3% )and grouped with P. penelrans in the phylogenetic tree. Based on the morphological characteristics and molecular phylogenelic analysis, strain PPhOl was identified as Pasteuria penelrans. Parasitism test results showed that spores of PPhOl had infective ability to juveniles of Meloidagyne incognita, M. javanka and M. arenaria.关键词
