Figure 1

Identification of sperm and sperm nuclei from hermaphroditic Panagrolaimus strain JU765. DIC imaging was used to identify sperm (left, panels A and C) and epifluorescence imaging was used to identify characteristically compact sperm nuclei (right, panels B and D). See Methods for details. A and B show nematode midbodies; C and D show a dissected spermatheca. Ann egg is indicated by "E", sperm nuclei by "SN", oocytes by "O", and sperm by "S". The scalebar represents 40 μm.
