蚯蚓再生研究进展

Research Progress about Regeneration of Earthworm

蚯蚓是土壤中的主要动物类群,它们可促进植物残枝落叶的降解、有机物质的分解和矿化等复杂过程,在陆地生态系统中具有重要的功能。同时,蚯蚓由于其快速和不断更新的能力被认为是研究再生的最佳材料,被当成研究发育、细胞生长分化和模式形成的模型。蚯蚓再生研究始于19世纪末,研究内容从生态学逐渐发展到分子生物学水平。综述了蚯蚓再生研究的历史;探讨了蚯蚓再生生物学的研究现状;分析了环境对蚯蚓再生的影响;并进一步分析了蚯蚓再生的机理。

As the main soil fauna,earthworm can improve the degradation of deciduous plants,and promote the complex process of organic matter decomposition and mineralization,which played an important role in terrestrial ecosystem.Earthworm was considered the best material of regeneration research because of the rapid and ceaseless renewal capacity.It also was considered the model of development research,cell differentiation and pattern formation.The history of regeneration research began at the end of 19th century.The research expanded from biology,ecology to molecular biology.In this paper,we summarized the history of earthworm regeneration research,discussed the research status of earthworm regeneration biology,analyzed the effect of environment on the earthworm regeneration capacity,and further analyzed the mechanism of earthworm regeneration.
