  近日,国际学术刊物Journal of Hazardous Materials (IF=9.038) 在线刊发了海洋所杨红生课题组最新研究成果“Programmed responses of different life-stages of the seagrass Ruppia sinensis to copper and cadmium exposure”。该研究解析了海草植物——中国川蔓草(Ruppia sinensis)不同生活史阶段对(Cu)和镉(Cd)的耐受性及毒性效应机制。研究结果为理解沉水植物对重金属元素的吸收与减毒机制提供了新视角。此外,结果还展现了中国川蔓草这一物种对于水环境中Cu、Cd的生物指示与修复潜力。
