Transcriptome and proteome analysis revealed tyrosine oxidation involved in the periostracum formation of the green mussel Perna viridis (Linnaeus)

Project description:Mollusk secretes a periostracum layer prior to the underlying calcified shell. This organic membrane serves as the first line of protection and primary template for shell orchestration. However, the chemical composition and formation mechanism of the periostracum layer is largely unknown. In this study, we applied transcriptomic, proteomics, physical and chemical analysis to unravel the mysteries of the periostracum formation in the green mussel Perna viridis (Linnaeus). Scanning electron microscopy examination and FTIR analysis showed that the periostracum layer was a multilayered organic membrane composed of polysaccharides, lipids and proteins. Interestingly, proteomic study identified components enriched in tyrosine and some enzymes evolved in tyrosine oxidation, indicating that tyrosine oxidation might play an important role in the periostracum formation. Moreover, comparative transcriptomics suggested that tyrosine-rich proteins were intensively synthesize in the periostracum groove. After being secreted, the periostracum proteins were gradually tanned by oxidation in the sea water, and the level of crosslink increased significantly as revealed by the ATR-FTIR. Our present study sheds light on the chemical composition and putative tanning mechanism of the periostracum layer in bivalve mollusk.

Reproductive Biology and Ecology of the Green Mussel Perna viridis: A Multidisciplinary Approach.

Project description:A multidisciplinary approach was applied to explore deeper knowledge about the reproductive biology and ecology of the green mussel (Perna viridis) by interlinking among ecological factors, ingested gut plankton, gonad fatty acid profile, and reproductive traits. Mussels were collected throughout the year from the coastal region of the Bay of Bengal of Bangladesh, and the histological analysis of 242 mussels revealed five stages of gametogenesis with an annual spawning season from January to April. The gonadosomatic index showed a strong correlation with the water quality parameters, ingested gut plankton groups, and gonadal fatty acids, and also displayed prominent effects of seasonality. In all datasets, we performed principal component analysis in which the first two principal components showed that seasonality explained >65% of the variability, and the multivariate spaces of seasonality corresponded to the gonad development. High salinity, nutrients, chlorophyll a, and plankton abundance in the water column were positively correlated with gonad development and the spawning of mussels. During the development stage, mussel ingested more plankton, particularly Bacillariophyceae and Pyrrophyceae, which were an important source of increased n-3 polyunsaturated fatty acids content in gonads. Furthermore, gonads accumulated more lipids and saturated fatty acids during the mature and spawning stages, which were probably utilized during embryogenesis and early larval development as energy sources and constituents of the cell membrane. This research provides a model toward a better understanding of reproductive biological traits and how these traits are interrelated with the surrounding environmental variables of the green mussel, which would be helpful in marine aquaculture and the sustainable exploitation of the fishery resources.
