Evidence of hermaphroditism and sex ratio distortion in the fungal feeding nematode Bursaphelenchus okinawaensis.

Shinya R, Hasegawa K, Chen A, Kanzaki N, Sternberg PW - G3 (Bethesda) (2014)

Bottom Line: Here, we demonstrate the hermaphroditism of the fungal feeding nematode Bursaphelenchus okinawaensis, which was formerly described as a parthenogenetic nematode, and we show its other unique sexual characteristics.B. okinawaensis is phylogenetically distant from established model nematodes such as C. elegans and is more closely related to some economically relevant parasitic nematodes.This newly discovered hermaphroditic nematode has great potential for evolutionary and parasitological research.

fig6: Stereomicroscope images of wild-type and mutant strains of Bursaphelenchus okinawaensis. (A and B) WT, wild-type. (C and D) Dpy, Dumpy. (E and F) Rol, Roller. (G and H) Unc, Uncoordinated. Scale bar represents 200 μm.

Mentions: The body shape of the B. okinawaensis wild-type is significantly narrower than that of C. elegans (Figure 6A). Eleven Dpy mutants that were shorter than the wild-type were isolated (Figure 6B). The frequency of appearance of candidate Dpy mutants was relatively high, but most of these Dpy animals were sterile. Some of the Dpy mutants were also roller and slightly sluggish.
