Pearl Microstructure and Expression of Shell Matrix Protein Genes MSI31 and MSI60 in the Pearl Sac Epithelium of Pinctada fucata by In Situ Hybridization [PDF]
PLoS ONE, 2013 Expression patterns of the shell matrix protein genes MSI31 and MSI60 in the pearl sac epithelium were examined by in situ hybridization 38 days after implantation, and related to pearl quality. A pearl sac that produced a nacreous pearl showed very weak

Cloning and functional characterization of PmΔ5FAD in pearl oyster Pinctada fucata martensii
Aquaculture Reports, 2022 Pinctada fucata martensii produces high-quality pearls. However, excess immune and inflammatory response after grafting operation will lead to nucleus rejection, pearl sac formation failure, and death of the host pearl oyster. Polyunsaturated fatty acids
