Cytodifferentiation during Spermiogenesis in Lumbricus Terrestris
The structural changes during spermiogenesis were studied on developing spermatids in seminal vesicles and receptacles of Lumbricus terrestris fixed in glutaraldehyde-osmium tetroxide and embedded in Epon-Araldite. The centriole plays a prominent role in the morphogenesis and organization of the microtubules of the manchette and flagellum. Microtubules arising from the centriole extend anterior...
متن کاملPurification and characterization of a basal body-associated Ca2+- binding protein
Isolated basal body complexes from the unicellular alga, Chlamydomonas reinhardtii were found to contain a low molecular mass acidic polypeptide, distinct from calmodulin, but with biochemical features in common with members of the calmodulin family of calcium-binding proteins. These common characteristics included a relative low molecular mass of 20 kD, an experimentally determined acidic pI o...
متن کاملCeramide glycanase from the earthworm, Lumbricus terrestris.
Ceramide glycanase (CGase) is an enzyme that cleaves the linkage between the sugar chain and the ceramide. To make this enzyme readily available, we have developed a simple method for preparing it from the earthworm, Lumbricus terrestris. The method involves Bio-Gel A-0.5m, octyl-Sepharose and p-aminophenylthiogalactoside-agarose column chromatography. By gel filtration, the molecular mass of e...
متن کاملPurification and characterization of antiviral protein from silkworm fecal matter
Antiviral proteins (AVP), present in silkworm fecal matter, show activity against nuclear polyhedrosis virus (NPV) in vitro and in vivo. The extract of silkworm fecal matter prepared in phosphate buffer solution of pH 7.5 was subjected to 50% solid ammonium sulfate precipitation to enrich AVP, then which was dialyzed. The dialysate was applied to the column containing silica gel-G, the column e...
متن کاملOntogenetic scaling of burrowing forces in the earthworm Lumbricus terrestris.
In hydrostatic skeletons, it is the internal fluid under pressure surrounded by a body wall in tension (rather than a rigid lever) that enables the stiffening of the organism, the antagonism of muscles and the transmission of force from the muscles to the environment. This study examined the ontogenetic effects of body size on force production by an organism supported with a hydrostatic skeleto...
