The phylogeny shows that Aphelenchoides besseyi are clustered together, and our sequences from different host plants can also be distinguished. The bootstrap values are indicated by numbers of percentage near each node, and a value higher than 90 are presented using red dots. GenBank ids of sequences include: EU196001.1 (Caenorhabditis elegans), AY508034.1 (Bursaphelenchus xylophilus isolate 186), KJ636306.1 (Bursaphelenchus xylophilus strain BursXyl1), AY284648.1 (Bursaphelenchus mucronatus), JQ348399.1 (Aphelenchus avenae), JQ957879 (Aphelenchoides blastophthorus), AY284643.1 (Aphelenchoides bicaudatus), JQ957890.1 (Aphelenchoides subtenuis), JQ957881.1 (Aphelenchoides ritzemabosi), AJ966475.1 (Aphelenchoides fragariae), and JQ957878.1 (Aphelenchoides besseyi isolate AChoBes1).
