Morphological and Molecular Characterization of Prevalent Plant-Parasitic Nematodes from Turfgrasses in Guangdong, China

The turfgrass industry has undergone a rapid development in Guangdong province, China, which the largest number of golf courses country. Recent surveys turfgrasses province revealed five plant-parasitic nematodes that are prevalent: Helicotylenchus dihystera, Mesocriconema xenoplax, Meloidogyne graminis, Hemicriconemoides rosae and Tylenchorhynchus leviterminalis. most prevalent species M. xenoplax found 60.6% 27.3% locations, respectively. These morphologically morphometrically described. Molecular characterization phylogenetic analyses using 18S rRNA D2-D3 expansion segments 28S sequences provided. This is first report on molecular relationships associated with Guangdong, China. work was step for future study including pathogenicity assay, relationship examination other pathogens control measures these turf to provide more precise effective management options superintendents.
