Fig. 5 Western blot analysis of MSP in E. brevis. a MSP has unusual mobility in gel and is found as protein with weight 36–38 kDa. Both male and female samples reveal MSP signal, because the latter include inseminated females. α-Tubulin was used as a loading control (approximate weight 55 kDa). b Peptide competition assay confirms reactivity of anti-MSP antibodies with protein band of 36–38 kDa

Fig. 2 Western blot analysis of MSP in P. redivivus. In adult animals, MSP is detected as double band with approximate weight 15 and 16 kDa. a Both male and female samples reveal MSP signal, because the latter include mated females. α-Tubulin was used as a loading control (approximate weight 55 kDa). b Analysis of young males and females. MSP is not detected in females, because most of them are unmated. Abbreviations: m, males; f, females

Fig. 3 Schematic representation of P. redivivus spermatozoa based on transmission electron microscopy. a Morphology of immature and mature spermatozoa. Immature spermatozoon is an unpolarized cell with nucleus devoid of nuclear envelope, mitochondria, and membranous organelles. Mature spermatozoon in female reproductive system is a bipolar cell with anterior pseudopodium and posterior main cell body containing chromatin, mitochondria, and membranous organelles that attached to cell membrane and open to the exterior via pores.

Fig. 1 Phylogeny of nematodes and MSP-based sperm motility. Phylogenetic relationships within phylum Nematoda derived primarily from SSU rDNA sequence data are given according to De Ley and Blaxter (2002). Suborders of the order Rhabditida, in which representatives highly homologous MSPs are found at DNA, RNA, or protein levels, are marked by underlining. Taxa whose species used in this study are marked with asterisks. Orders Trefusi- ida, Isolaimida, Dioctophyma- tida, Muspiceida, Marimermith- ida, and Desmoscolecida are not shown in this tree
