Figures & Tables

Figure 1:

(A) Visual damage symptoms from the Pacific shoot-gall nematode, A. pacificae, on a golf course tee box in Clark County, Washington. (B) Basal galling and swelling of annual bluegrass (P. annua L.) tillers from the tee box. (C) A. pacificae second-stage juvenile. Scales: 200 μm. S, stylet; EP, excretory pore; GP, genital primordia; A, anus.

Figure 2:

Phylogenetic tree, derived by RAxML analysis of the ITS gene region for A. pacificae. Alignments and trees were constructed in Geneious using MAFFT alignment tool. The tree was run with 100 bootstraps, only bootstrap support >70% are shown to increase readability. ITS, internal transcribed spacer; RAxML, randomized axelerated maximum likelihood.
