QX DISEASE RESISTANCE IN SYDNEY ROCK OYSTERS. QX is a fatal disease of Sydney rock oysters. The protozoan parasite that causes QX has been identified in more than one third of oyster farming areas on the east coast of Australia. Disease outbreaks have already destroyed the oyster industry in some of those areas. This project tests whether a novel form of defensive protein that has been identified in some oysters can be used as a genetic marker of QX disease resistance. The selective breeding of ....QX DISEASE RESISTANCE IN SYDNEY ROCK OYSTERS. QX is a fatal disease of Sydney rock oysters. The protozoan parasite that causes QX has been identified in more than one third of oyster farming areas on the east coast of Australia. Disease outbreaks have already destroyed the oyster industry in some of those areas. This project tests whether a novel form of defensive protein that has been identified in some oysters can be used as a genetic marker of QX disease resistance. The selective breeding of disease resistant oysters based on such a genetic marker would help to control QX and secure the future of Australia's rock oyster industry.Read moreRead less
