MetabolomicsFood Deprivation Enhances Disease Resistance: Underlying Mechanisms in Oysters Confronted with Pacific Oyster Mortality Syndrome

Variation in food availability can shape host susceptibility and pathogen virulence, thereby impacting disease outcomes. An ad libitum diet may enhance host physiology and immunity but it can also favor pathogen proliferation. Here, we investigated how food availability (ad libitum vs. starvation...

TranscriptomicsTranscriptomic profiling of gametogenesis in triploid oysters
Background Triploidy can occur in all species but is often lethal in birds and mammals. In amphibian, invertebrates and numerous species of fishes, triploid animals are viable and undistinguishable from diploid individuals. Gametogenesis is often affected and most animals are sterile for at least o...

TranscriptomicsDifferential gene expression profilings between diploid and triploid Fujian Oyster
The systematic deep sequencing analysis provided a comprehensive understanding of the transcriptome complexity of 2n and 3n Fujian oyster. This information broadens our understanding of the mechanisms of C.angulata polyploidization and contributes to molecular and genetic research by enriching the o...

TranscriptomicsWhole transcriptome profiling of successful immune response to Vibrio infections in the oyster Crassostrea gigas by digital gene expression analysis
The cultivated Pacific oyster Crassostrea gigas has suffered for decades large scale summer mortality phenomenon resulting from the interaction between the environment parameters, the oyster physiological and/or genetic status and the presence of pathogenic microorganisms including Vibrio species. T...

ProteomicsDIA-based proteomic analysis of gonads in oysters Crassostrea gigas
Triploid oysters have poor gonadal development, which can not only bring higher economic benefits but also have a potential application in the genetic containment for aquaculture. However, the key factors that influence germ cell development in triploid oysters remain unclear. In this study, data-i...

ProteomicsPROTEOMIC RESPONSE OF EARLY JUVENILE PACIFIC OYSTERS TO TEMPERATURE
The shellfish aquaculture industry provides a sustainable food source and jobs for a growing population. Oysters are the primary aquaculture species produced in the United States and account for a significant portion of seafood exports. Shellfish hatcheries have been experiencing frequent mass morta...

TranscriptomicsComparison of gene expression from surviving and dying Pacific oysters reveals a motality signature
This experiment was designed to enable the identification of field mortality sensitive Pacific oysters while also permitting the repetitive, non-lethal sampling of tissue from identifiable individual oysters. These samples have been difficult to obtain because pre-mortality phenotypes are obscured b...

TranscriptomicsTranscriptome response to salinity stress in the Pacific oyster Crassostrea gigas
Low salinity is one of the main factors limiting the distribution and survival of marine species. As a euryhaline species, the Pacific oyster Crassostrea gigas can be tolerant to relative low salinity. Through Illumina sequencing, we generated two transcriptomes with samples taken from gills of oyst...

TranscriptomicsDiurnal gills transcriptome of the oyster Crassostrea gigas fed with non-harmful and harmful algae
To assess the diurnal gene expression in gills of oyster Crassotrea gigas, gills of 6 oysters were pooled and analyzed by RNa-seq every 4h for 52h (i.e. 13 sampling times). This procedure was executed simultaneously for control oysters fed with the non-harmful algae Heterocapsa triquetra (H.t condit...
