Marine environmental change directly affects bivalve growth and survival. Exoskeleton formation, the main energy dissipation in physiological metabolism, typically reflects body of bivalve. However, how bivalves regulate biomineralization exoskeleton under stressors is not yet clear. Long non-coding RNA regulates various life processes through complex mechanisms vertebrates invertebrates. In this research, we cloned complete sequence a mantle-specific expressed long (designated as LncMPEG1 ) from pearl oyster, Pinctada fucata martensii . A quantitative real-time PCR analysis showed that expression was significantly high early umbo larvae juveniles, which would be critical periods shell development. identified outer epithelium middle fold mantle edge, pallial, center by using situ hybridization. Additionally, stimulated damage, alien invasion, heat cold temperature stress, hypoxia stress. mantle, decreased detected interference, can cause irregular crystals on inner surface prismatic layer nacre shells. Therefore, propose could key regulator responds to stress
