摘要
在广东省园林植物线虫调查期间,从粉单竹Bambusa chungii根部土壤中分离到一种螺旋线虫。经详细的形态学观察和测量数据比较,将其鉴定为尖尾螺旋线虫Helicotylenchus cuspicaudatus,并获得了尖尾螺旋线虫rDNA的28SD2-D3区和ITS序列,为今后螺旋线虫的种类鉴定提供了分子数据。尖尾螺旋线虫为中国新记录种。
A species of spiral nematode was isolated from the rhizosphere soil of Bambusa chungii during the survey of parasitic nematodes associated with landscape plants in Guangdong Province.The detailed morphological study confirmed the species as Helicotylenchus cuspicaudatus.The fragments of rDNA 28S D2-D3 and ITS were amplified and sequenced,which provided molecular characters for rapid and accurate identification of this species in the future.H.cuspicaudatus was reported in China for the first time.
