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: B. okinawaensis males successfully mated only with sperm-depleted old hermaphrodites, and the spermatid sizes of males were almost the same as those of hermaphrodites.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.

Distribution of spermatid cross-sectional areas in hermaphrodites and males in Bursaphelenchus okinawaensis. The cross-sectional area of spherical spermatids was measured using ImageJ software. A total of 100 sperm from 80 hermaphrodites and 126 sperm from 24 males were measured.

fig7: Distribution of spermatid cross-sectional areas in hermaphrodites and males in Bursaphelenchus okinawaensis. The cross-sectional area of spherical spermatids was measured using ImageJ software. A total of 100 sperm from 80 hermaphrodites and 126 sperm from 24 males were measured.

Mentions: The average sperm size, as measured by the cross-sectional area, of males and hermaphrodites of B. okinawaensis was 12.2 μm2 and 11.9 μm2, respectively. There is no significant difference in the distribution of spermatid size between males and hermaphrodites (P = 0.61, one-way ANOVA) (Figure 7).
