微生物对环境遗传适应和质粒的分子生态效应

微生物对环境的遗传适应是进化的机制，它与环境因子之间存在着复杂的信号网络，调节微生物与环境新奇信号（污染物质）之间的相互适应、质粒的形成与存在正是宿主细胞获得这种适应的产物，由于它能在自然环境中广泛传播，导致了物种的多样性．本文概述了微生物对环境污染物的应答和质粒的分子生态效应

Microbial genetic adaptability to environment and molecular ecological efficiency of plasmid.

The genetic adaptability of microbes to environment is the mechanism of microbial evolution. There are complex signal networks between microbes and environmental factors to regulate the mutual adaptability of microbes and environmental novel signals (pollutants). The formation and the presence of plasmids make host cells obtain this adaptability. The wide spread of plasmids in natural environment results in species diversity. This paper reviewed the response of microbes to pollutants and the molecular ecological efficiency of plasmids.
