“…Unidirectionality of microfibril bundles was demonstrated in the ~-chitin system of deep sea thermal vent worms . In this case, the cup-shaped microvilli, which locates at the interface between sublumen and cell, was found to be responsible for chitin synthesis, and the membrane is more closely associated with this f3-chitin synthesis than are the vesicles thought to be the synthesizing site for c~-cbitin (Shillito et al 1995). The assembling mechanism of the glomerulocyte cellulosic bundles was reported by Kimura and Itoh (1995).…”

Summary. Glomerulocyte cellulosic bundles of Polyzoa vesiculiphora were investigated by microdiffraction and high-resolution electron microscopy. In each bundle, hundreds of cellulose microfibrils, having a rectangular cross-sectional shape, are packed regularly with their 0.6 nm lattice planes parallel to each other. Lattice images reveal that the 0.6 nm plane is parallel to the longer edge of the cross section which is similar to the lattice organization of cellulose with a squarish cross section in Valonia spp. More interestingly, all the microfibrils in a bundle have the same directionality of crystallographic c-axis, which suggests that the biosynthesis of the microfibrils within particular bundle occurs unidirectionally.

“…Therefore it has frequently been used as a chitin-localization probe (e.g. Shillito et al, 1995;Neuhaus et al, 1997;Lemburg, 1998). The combining site of wheat germ agglutinin was reported to be complementary to a sequence of three b-(1 / 4)-linked N-acetyl-glucosamine residues (Debray et al, 1981), but interactions of WGA lectin with Nacetylneuraminic acid containing glycoconjugates (Monsigny et al, 1980) and poly-N-acetyllactosaminoglycans (Gallagher et al, 1985) were shown to occur.…”

“…The site of secretion of chitin microcrystallites has been located very precisely in Riftia pachyptila with an immuno-gold labelling technique (Shillito et al, 1993(Shillito et al, , 1995b. There is labelling inside the hollow of the cup but not in the intracellular compartment of the gland cell, therefore the chitin molecules must be assembled in the cups.…”

Pogonophora (Annelida): form and function

2005

View full text Add to dashboard Cite

Pogonophora, also known as Siboglinidae, are tube-dwelling marine annelids. They rely on endosymbiotic chemoautotrophic bacteria for nutrition and their anatomy and physiology are adapted to their need to obtain both oxygen and reduced sulphur compounds. Frenulate pogonophores are generally long and slender, sediment-living tubeworms; vestimentiferans are stouter, inhabitants of hydrothermal vents and cool seeps; and moniliferans or sclerolinids are very slender inhabitants of decaying wood and sulphidic sediments. The anatomy and ultrastructure of the three groups are compared and recent publications are reviewed. Annelid characters are the presence of chaetae and septa, concentrated at the hind end. The adaptations to a specialised way of life include, in particular, the chitinous tube; the anterior appendages that function as gills; the internal tissue called the trophosome, where the endosymbiotic bacteria live; and the blood vascular system that transports oxygen, sulphide and carbon dioxide to the trophosome.
