Phylogenetic relationships of Tylenchus zeae n. sp. with other select Tylenchidae, as inferred from an 822 bp alignment of 28S rRNA sequences, according to the GTR + I + G model of nucleotide substitution and incorporated into MrBayes (MB) as described. A 50% majority rule consensus tree was generated with posterior probabilities (PP) shown on appropriate branches, with Bursaphelenchus mucronatus as the outgroup. New sequences are indicated in bold.

Specimens of a tylenchid nematode were recovered in 2019 from soil samples collected from a corn field, located in Pickens County, South Carolina, USA. A moderate number of Tylenchus sp. adults (females and males) were recovered. Extracted nematodes were examined morphologically and molecularly for species identification, which indicated that the s...

... rex Andrassy (1979) T. rex Geraert plate and extending three or four annules beyond the labial plate. Phylogenetic analysis of the 28S rRNA gene sequence alignment grouped T. zeae n. sp. with several undescribed Tylenchidae spp. apart from T. arcuatus (Fig. 5), in contrast with their close relationships shown by the other two markers examined. Qing and Bert (2019) also noted a discordance between 18S and 28S rRNA gene trees for the Tylenchidae, indicating the possibility variable copies or pseudogenes were amplified from nematodes due to PCR and primer bias. As shown in previous studies (Bai ...
