“…The Xiphinema population IEBR-NEMA 4776 was largely in agreement with the morphology of X. hunaniense from turmeric in Vietnam, except for odontophore (69−75 vs 70−71 µm), V% (25−27 vs 24.2−25), and tail length (56−67 vs 44−46 µm). Interestingly, variations of the above indices were also shown in the type population and other recorded populations of X. hunaniense from China, Nigeria, Australia, Malaysia, and Thailand (Long et al, 2014;Wang & Wu, 1992;Wu et al, 2007). Although the type population of X. hunaniense was found on tea (Wang & Wu, 1992), this study provides the first report of X. hunaniense on tea in northern Vietnam, added to the total of four species of the genus Xiphinema on tea in Vietnam (Nguyen & Nguyen, 2000).…”

The dagger nematodes, Xiphinema spp., are migratory root-ectoparasitic nematodes that cause damage to a wide range of wild and cultivated plants over the world. In Vietnam, this nematode group has been studied mainly based on morphological characterizations. During a survey of pathogens associated with tea, a plant with many medicinal and therapeutic potentials, a population of Xiphinema hunaniense was recorded. This study provides the first morphological and molecular characterizations of Xiphinema hunaniense found on Tea in Vietnam. The 28S rDNA, and 18S rDNA phylogenetic trees of the genus Xiphinema are also provided. 18S rDNA sequence of X. hunaniense is also submitted to GenBank for the first time.

“…Morphology and morphometrics of this population are highly similar to the type population of X. hunaniense except for smaller a value (43-48 vs 51-57), c value (42-49 vs 53-63), longer stylet (190-201 µm vs 180-187 µm), wider width at pharyngo-intestinal junction (43-44 µm vs 21-23 µm). However, these morphometric variations have been reported from other populations of X. hunaniense (Luc, 1981;Wu et al, 2007;Long et al, 2014). Two 28S rDNA sequences (1 bp difference) of the Vietnamese population of X. hunaniense were obtained, 942 to 944 bp long.…”

For the first time, a survey of plant-parasitic nematodes in the Central Highlands of Vietnam discovered a population of Xiphinema hunaniense Wang & Wu, 1992. The Vietnamese population of X. hunaniense is characterized by having an offset lip region, lack of anterior genital branch, vagina directed backward, and a digitate tail. Morphological features and morphometrics of this population are in agreement with the type population of X. hunaniense except for some variations. In addition, molecular characterization of this population and phylogenetic tree of 28S rDNA sequences of the genus are also provided.

Summary During a nematode biodiversity survey from 2012 to 2014 in Shenzhen, China, ten nematode populations (SZX1301–SZX1310) of Xiphinema were recovered from rhizosphere of different plants, namely Acacia mangium (SZX1306), A. confuse (SZX1309), Blechnum orientale (SZX1301, SZX1302, SZX1307, SZX1308), Litchi chinensis (SZX1304, SZX1310) in Tianxinshan and Gleichenia linearis (SZX1303, SZX1305) in Yangmeikeng environmental monitoring sites. Morphological and molecular profiles of these populations were determined. Three species of Xiphinema, i.e., X. hunaniense Wang & Wu, 1992, X. brasiliense Lordello, 1951 and X. americanum Cobb, 1913 sensu lato were identified using morphological characters and molecular data of partial 18S and 28S D2–D3 rDNA expansion segments. Four populations (SZX1301–SZX1304) were X. hunaniense, one population (SZX1305) X. brasiliense, and five populations (SZX1306–SZX1310) X. americanum s.l.. Phylogenetic analysis based on sequences of the 28S rDNA D2–D3 expansion segment revealed these three species are all distinct species and supported a close relationship with their corresponding species. This is the first report of X. hunaniense, X. brasiliense and X. americanum s.l. in their hosts except for L. chinensis.
