Developmental significance of D quadrant micromeres 2d and 4d in the oligochaete annelid Tubifex tubifex.
The annelidTubifex tubifex is a cosmopolitan freshwater oligochaete and a member of the Spiralia, a large group of invertebrate phyla displaying spiral development. Because its developing eggs are easily obtained in the laboratory, this animal has long been used as material for developmental studies, especially spiralian embryology. In spiralian embryos, it has long been known that one blastome...
متن کاملEmbryonic expression of a decapentaplegic gene in the oligochaete annelid Tubifex tubifex.
We have cloned and characterized the expression of a decapentaplegic homologue (designated Ttu-dpp) from the oligochaete annelid Tubifex tubifex. RT-PCR analysis and in situ hybridization revealed that Ttu-dpp begins to be expressed around the time of the onset of ectodermal germ band (GB) elongation (i.e., the onset of gastrulation). At this time, Ttu-dpp expression is detected in the anterior...
متن کاملBenzo(a)pyrene inhibits the role of the bioturbator Tubifex tubifex in river sediment biogeochemistry.
The interactions between invertebrates and micro-organisms living in streambed sediments often play key roles in the regulation of nutrient and organic matter fluxes in aquatic ecosystems. However, benthic sediments also constitute a privileged compartment for the accumulation of persistent organic pollutants such as PAHs or PCBs that may affect the diversity, abundance and activity of benthic ...
متن کاملPersistent infection of Myxobolus cerebralis, the causative agent of salmonid whirling disease, in Tubifex tubifex.
The objective of this study was to quantify and determine the periodicity in the release of the triactinomyxon (TAM) stage of Myxobolus cerebralis, the causative agent of salmonid whirling disease, by its aquatic oligochaete host Tubifex tubifex. For this, 24 individual T. tubifex (infected as a group at 15 C) were examined daily for the release of M. cerebralis TAMs, and the number of waterbor...
متن کاملEffect of Pyridine and Formaldehyde on a Macrophyte (lemna Minor L.) and a Sludge Worm (tubifex Tubifex Müller) in Fresh Water Microcosms
Pyridine, a suspected genotoxic and formaldehyde, a potent carcinogen, are present in several industrial wastewater including commercial solvent, resin and pesticide manufacturing industries. The extent of pyridine and formaldehyde toxicity in aquatic organisms is unknown. Therefore, in present study the toxicity of pyridine and formaldehyde were investigated in artificial aquatic ecosystem (mi...
