Transcriptome and exosome proteome analyses provide insights into the mantle exosome involved in nacre color formation of pearl oyster Pinctada fucata martensii

The pearl oyster Pinctada fucata martensii is an economically important species of marine pearl culture, and tissue of mantle plays an essential role in pearl formation. Here, the extracted exosomes from mantle of P. f. martensii were analyzed by quantitative protein TMT sequencing. We wanted to verify if exosomes are the important vehicle in the process of biomineralization (e.g., pearl and shell formation), especially the color formation in shellfish. Finally, we got some results which indicated the importance of exosomes in sides of proteins, and it can also contribute to other researches related to the exosomes or pearl oyster.
