The effect of low salinity on phenoloxidase activity in the Sydney rock oyster, Saccostrea glomerata
This study tested the effects of low salinity on phenoloxidase activity in Sydney rock oysters (Saccostrea glomerata). Phenoloxidase is a key component of the immune system in S. glomerata. Previously, we have shown that decreased phenoloxidase activity is associated with susceptibility to fatal QX disease. In the current study, laboratory-based experiments were used to identify factors that co...
متن کاملTranscriptome Analysis of the Sydney Rock Oyster, Saccostrea glomerata: Insights into Molluscan Immunity
BACKGROUND Oysters have important ecological functions in their natural environment, acting as global carbon sinks and improving water quality by removing excess nutrients from the water column. During their life-time oysters are exposed to a variety of pathogens that can cause severe mortality in a range of oyster species. Environmental stressors encountered in their habitat can increase the s...
متن کاملPersistence of Positive Carryover Effects in the Oyster, Saccostrea glomerata, following Transgenerational Exposure to Ocean Acidification
Ocean acidification (OA) is predicted to have widespread implications for marine organisms, yet the capacity for species to acclimate or adapt over this century remains unknown. Recent transgenerational studies have shown that for some marine species, exposure of adults to OA can facilitate positive carryover effects to their larval and juvenile offspring that help them to survive in acidifying...
متن کاملInvestigation of Body Size Effect on Bioaccumulation Pattern of Cd, Pb and Ni in the Soft Tissue of Rock Oyster Saccostrea cucullata from Laft Port
Nowadays, contamination of heavy metals in aquatic ecosystems is one of the major world problems in developing and developed countries. Among various aquatics, shellfish species, especially bivalves can be used as bioindicator, because of purification system, potential bioavailability of impurities in environment as well as accumulation of some heavy metals in their body. Among bivalves, oyst...
متن کاملPhenoloxidase and QX disease resistance in Sydney rock oysters (Saccostrea glomerata).
QX is a fatal disease in Sydney rock oysters (Saccostrea glomerata) that results from infection by the protistan parasite, Marteilia sydneyi. Since 1997, the New South Wales Fisheries Service has bred S. glomerata for resistance to QX disease. The current study shows that the QX resistance breeding program has selected oysters with enhanced phenoloxidase (PO) activities. The third generation of...
