... are already established during activation. To investigate this,skinned fibre bundles of the anterior byssus retractor muscle of Mytilus edulis were maximally activated with Ca 2+ and subsequently exposed to 10 mmol l -1 orthovanadate (V i ) or 5 μmol l -1 blebbistatin to inhibit the force-generating myosin...

...Gretchen M. Moeser; Heather Leba; Emily Carrington SUMMARY The blue mussel Mytilus edulis maintains a strong attachment to the substrate in high energy environments by producing byssal threads. On the shores of Rhode Island, USA, mussel attachment strength increases twofold in spring compared...

...Marion Christine Höpflinger; Olena Andruchova; Oleg Andruchov; Herbert Grassberger; Stefan Galler SUMMARY Moderate alkalisation is known to terminate the catch state of bivalve mollusc smooth muscles such as the anterior byssus retractor muscle (ABRM) of Mytilus edulis L. In the present study, we...

...Masao Mukou; Hirohiko Kishi; Ibuki Shirakawa; Takakazu Kobayashi; Katsutoshi Tominaga; Haruka Imanishi; Haruo Sugi SUMMARY The anterior byssal retractor muscle (ABRM) of the bivalve Mytilus edulis shows a prolonged tonic contraction, called the catch state. To investigate the catch mechanism...

... on Mytilus edulis , with few detailed comparisons with other mussels. M. galloprovincialis , a closely related species, provides an opportunity for a thorough comparison. Three full-length cDNA clones encoding the byssal collagens, precollagen D(preCol-D), preCol-NG and preCol-P, were isolated from M...

...Kathryn J. Coyne; J. Herbert Waite ABSTRACT We recently described the cDNA sequence for a unique collagenous protein, preCol-P, in the byssal threads of the marine mussel Mytilus edulis . The translated amino acid sequence encodes an unprecedented block-copolymer-like sequence with a central...

... that Geukensia demissa gills use sulfide as a respiratory substrate when given the choice and thus function metabolically as facultative chemolithoheterotrophs. Similar conclusions could not be drawn for the ciliated gills from Mytilus edulis , a marine mussel from aerated habitats, or for the ciliated lungs...

... between components of these systems. As a case study, we apply the model to the blue mussel Mytilus edulis by investigating the effect on performance of changes in the gap between neighboring tentacles. Our model suggests that the observed gaps between tentacles in M. edulis reflect flow-maximizing...

...Karl Erik Zachariassen; Anders Johny Olsen; Tore Aunaas ABSTRACT Free amino acids in the posterior adductor muscle of mussels ( Mytilus edulis ) occur in a high-energy gradient group, with energy gradients of 15–18 kJ mol −1 (aspartate, beta-alanine, glycine, taurine and threonine), and a low...

...Xiaoxia Qin; J. Herbert Waite ABSTRACT Byssal threads of the common mussel Mytilus edulis contain collagenous molecules from which two pepsin-resistant fragments have been isolated and characterized. These show a complementary distribution along the length of the thread, such that one predominates...

...Jan Fredrik Børseth; Tore Aunaas; Sigrun Einarson; Trond Nordtug; Anders Johny Olsen; Karl Erik Zachariassen ABSTRACT This study deals with the effects of chemical pollutants on the transmembrane potential difference for sodium in smooth muscle cells of Mytilus edulis . A method for indirect...

... Mytilus edulis Mytilus californianus gill epithelia Intertidal animals may be exposed to abrupt, but transient, changes in external salinity ( Stickle and Ahokas, 1974 ). For osmoconforming animals, including marine mussels of the genus Mytilus , this can result in large changes...

...Michael A. Rice; Grover C. Stephens ABSTRACT The uptake of amino acids by the non-gill epithelia of the mantle cavity of Mytilus edulis L. was studied and compared with uptake by the gills. Amino acid entry rates and the subsequent distribution of amino acids to the other tissues of the animals...

...Catherine M. Linehan ABSTRACT When the anterior byssal retractor muscle (ABRM) of Mytilus edulis was subjected to a sudden reduction in temperature during a contractionrelaxation cycle, a tension increment, the cold-induced contracture (CIC), was observed. The CIC could be obtained in a muscle...
