Nuclear Changes during Spermiogenesis in a Pulmonate Snail
Changes in both external form and internal arrangement of nuclear material have been investigated in the differentiation of the sperm of the pulmonate snail, Otala lactea. Sperm head differentiation begins with a flattening of the previously spherical nucleus and a thickening of the nuclear envelope covering the anterior and posterior surfaces of that nucleus. Tail filaments can be seen in the ...
متن کاملCHANGES IN NUCLEAR HISTONES DURING FERTILIZATION, AND EARLY EMBRYONIC DEVELOPMENT IN THE PULMONATE SNAIL, Helix aspersa
Calf thymus histories comprising two fractions, one rich in lysine, the other having roughly equal amounts of lysine and arginine, Loligo testes histones rich in arginine, and salmine, are compared with respect to their amino acid compositions, and their staining properties when the proteins are fixed on filter paper. The three types of basic proteins; somatic, arginine-rich spermatid histones,...
متن کاملNuclear changes during spermiogenesis in two chrysomelid beetles.
Ultrastructural and cytochemical studies were carried out on sperm nucleus of the beetles, Coelomera lanio and Diabrotica speciosa. Nuclear development involves changes in the shape and in the degree of chromatin condensation, with specific aggregation patterns of DNA-histone complex occurring during this process. Lamellar and paracrystalline arrangements of the nuclear material were observed i...
متن کاملThe nuclear lamina during human spermiogenesis
The nuclear lamina takes centre stage during spermiogenesis, the post-meiotic phase of spermatogenesis, when haploid round spermatids differentiate into spermatozoa: the acrosome and flagellum develop at opposite nuclear poles, the nucleus elongates and, as the nuclear histones are replaced with protamines, the chromatin condenses, to produce the highly compacted pyriform nucleus of the mature ...
متن کاملDevelopment of 10 microsatellite loci in the pulmonate snail Biomphalaria kuhniana (Mollusca, Gastropoda).
We characterized 10 variable microsatellite loci in the freshwater snail Biomphalaria kuhniana, as well as conditions for multiplexing and co-loading sets of loci. Two to five alleles were detected per locus over the two studied populations in Venezuela. High inbreeding coefficients suggest high selfing rates. Cross-species amplification provided some variability at eight and three loci in the ...
