ABSTRACTPlethodontid salamanders have n = 13 or 14 large metacentric or sub-metacentric chromosomes. Sperm nuclei from Plethodon cinereus measure 72×1 μm. The nucleoprotein of spermatids is at first finely granular. In elongate spermatids it clumps into larger granules, which then fuse to form the compact nucleoprotein of the mature sperm. The nuclei of mature sperm are negatively birefringent with respect to their length. — 3H RNA complementary to high-density satellite DNA of centromeric heterochromatin in P. cinereus has been hybridized in-situ to spermatids and sperm, and its site of binding to these cells has been examined by autoradiography. Labelling of round spermatid nuclei is localized in a single patch. Elongate spermatid nuclei are labelled only over the rear quarter of the nucleus. Label over the nuclei of mature sperm is localized in a region extending 10–20 μm forwards from the rear of the nucleus. — In P. cinereus the ribosomal genes are located near the centromere on the short arm of chromosome 7. 3H ribosomal RNA hybridizes to a single patch in round spermatid nuclei. Elongate spermatid nuclei show label over a short segment of the rear half of the nucleus. In spermatids nearing maturity the labelled region is never more than 20 μm long. — These results indicate that in P. cinereus each chromosome is arranged in a U formation with its centromere at the base of the sperm nucleus, and its arms extended forwards along the length of the nucleus. — Among plethodontids, increase in ‘C’ value and corresponding increase in chromosome size is accompanied by increase in the length rather than the width of the sperm nucleus. — 3H ribosomal RNA hybridizes to a short segment in spermatid and sperm nuclei from Xenopus and Triturus. In these animals, the position of the labelled segment varies from sperm to sperm. More... »
