Food quality and season affect gene expression of the mucosal lectin MeML and particle sorting in the blue mussel Mytilus edulis
نویسندگان
چکیده
The blue mussel, Mytilus edulis, is able to use biochemical cues to sort food particles. Recently, a mucosal lectin (MeML) identified in pallial organs of M. edulis was suggested to play a role in the capture and sorting of food particles. The current study presents data obtained in 2010 showing that sorting efficiencies and MeML gene expression in M. edulis increased when mussels were either fed poor quality food or starved. In addition, results suggest that particle capture and degree of selection increased during the spawning period, although the quality of food delivered to mussels before the experiments seemed to have a stronger impact on particle-sorting efficiency. Overall, the impact of both endogenous (physiological status) and exogenous (food quality) factors were shown to affect the expression of MeML in mussel feeding organs, and the food sorting abilities.

Identification and molecular characterization of a mucosal lectin (MeML) from the blue mussel Mytilus edulis and its potential role in particle capture.
Molecular recognition of food particles has been suspected to play an important role in particle selection in suspension feeding bivalves. Lectins are a group of sugar-binding proteins that are widely involved in biological recognition. They have been reported in mucus covering bivalves feeding organs and were recently shown to mediate particle sorting in these animals. In this study, we report...
متن کاملThe effect of high-pressure spraying for tunicate control on byssal thread characteristics in the cultured blue mussel (Mytilus edulis Linnaeus, 1758)
Mussel growers in Prince Edward Island (PEI), Canada, currently use high-pressure water spraying (~700 psi) to mortally injure or dislodge invasive tunicates from mussel product and gear. An added benefit of this process may be the stimulation of byssal thread production, leading to improved mussel attachment. This study measured byssal thread abundance and thickness in cultured blue mussel Myt...

متن کاملEffect of infection by the metacercarial trematode Renicola roscovita on growth in intertidal blue mussel Mytilus edulis
Trematode parasites can affect the molluscan hosts serving as first intermediate hosts in their complex life-cycles in manifold ways, but little is known about trematode-induced effects in second intermediate mollusc hosts. In 2 field experiments in 2 habitats and at 2 tidal heights (low and mid intertidal), controlled infection of blue mussels Mytilus edulis serving as second intermediate host...
