Examination Of Polymorphism In The Serine Proteinase Inhibitor Gene In The Eastern Oyster, Crassostrea Virginica., Aine Lehane
Examination Of Polymorphism In The Serine Proteinase Inhibitor Gene In The Eastern Oyster, Crassostrea Virginica., Aine Lehane
Senior Honors Projects
Oysters are a keystone species; they are filter-feeders and reef-builders. Additionally, oysters are extremely important within the shellfish aquaculture industry; they are the second most widely produced species in world aquaculture production. Eastern oysters, Crassostrea virginica, are produced in aquaculture and are unfortunately susceptible to Dermo disease. Dermo is caused by a protozoan parasite, Perkinsus marinus, and infection is often fatal in oysters due to widespread tissue damage and blockage of blood vessels. Research in oyster disease is particularly needed because disease is one of the largest impediments faced by the aquaculture industry as entire oyster populations can …

Morphological features such as size and shape are the most common focus in studies of heterochronic change. Frequently, these easily observed and measured features are treated as a major target of selection, potentially ignoring traits more closely related to fitness. We question the primacy of morphological data in studies of heterochrony, and instead suggest that principal sources of fitness, such as life history characteristics, are not only the chief targets of selection, but changes in them may necessitate changes in other (subordinate) elements of the organism. We use an experimental approach to investigate the timing of metamorphosis and maturation in …

Transmissible spongiform encephalopathies (TSEs) are a group of diseases that affect the nervous system and lead to death. The putative infectious agent is the host-encoded prion protein (PrP) and it appears that the development of scrapie in sheep is closely related to polymorphisms in the host PrP gene. The aim of this study was to investigate three well-known polymorphisms in exon 3 of the PrP gene (at codons 136, 154, and 171) that have a clear and significant effect on scrapie in sheep. Four other polymorphisms (at codons 145, 185, 231, and 237) that are yet undefined were also investigated. …

The aim of this study was to determine the genotypes of bovine growth hormone and to investigate their association with daily weight gain in the Zavot cattle breed. The bovine growth hormone (GH) genotypes of 45 male Zavot cattle were identified by PCR-RFLP. The effect of the bovine growth hormone gene on daily weight gain was estimated from a dataset obtained from cattle up to the age of 9 months. The mean differences of carcass weight or carcass yield among the genotype groups were assessed by analysis of covariance (ANCOVA). Two alleles for bovine growth hormone locus, L and V, …
