Multiple-locus heterozygosity, physiology and growth at two different stages in the life cycle of the Chilean oyster Ostrea chilensis [PDF]

open access: yes, 1996
A random sample of 150 individuals of a laboratory-produced cohort of Ostrea chilensis Philippi, 1845 was taken at 10 and 36 mo of age to estimate physiological variables and individual heterozygosity using 4 loci (Lap, Pgi, Pgm and Ca).

Unusual conservation of mitochondrial gene order in Crassostrea oysters: evidence for recent speciation in Asia

open access: yesBMC Evolutionary Biology, 2010
Background Oysters are morphologically plastic and hence difficult subjects for taxonomic and evolutionary studies. It is long been suspected, based on the extraordinary species diversity observed, that Asia Pacific is the epicenter of oyster speciation.

Age structure, carbonate production and shell loss rate in an Early Miocene reef of the giant oyster Crassostrea gryphoides [PDF]

open access: yesBiogeosciences, 2016
We present the first analysis of population structure and cohort distribution in a fossil oyster shell bed based on 1121 shells of the giant oyster Crassostrea gryphoides (von Schlotheim, 1813).

Paenibacillus crassostreae sp. nov., isolated from the Pacific oyster Crassostrea gigas

open access: yesInternational Journal of Systematic and Evolutionary Microbiology, 2018
A Gram-stain-positive, endospore-forming, rod-shaped, aerobic bacterium, designated LPB0068T, was isolated from a Pacific oyster (Crassostrea gigas) in Korea. This isolate was found to share the highest 16S rRNA gene sequence similarity with Paenibacillus macquariensis subsp. macquariensis DSM 2T (98.1 %) and Paenibacillus macquariensis subsp. defensor

Transcriptome Analysis of Crassostrea sikamea (♀) × Crassostrea gigas (♂) Hybrids Under Hypoxia in Occluded Water

open access: yesFrontiers in Marine Science, 2022
Hypoxia is considered to be one of the key factors affecting the survival of ocean organisms, it is necessary to parse the molecular processes involved in response to hypoxia. As a potential breeding species, the hybrid of Crassostrea sikamea (♀) × Crassostrea gigas (♂) shows valuable heterosis in survival and growth traits.
