进化生态学中水平基因转移的统计力学

Statistical Mechanics of Horizontal Gene Transfer in Evolutionary Ecology

Nicholas Chia, Nigel Goldenfeld

摘要:

生物世界,特别是其主要的微生物组成部分,是强烈的相互作用,并可能由集体效应主导。在这篇综述中,我们为统计物理学家简要介绍了活细胞通过转移基因进行遗传交流的方式,以及它们可以重组基因组以应对环境压力的方式。我们讨论了基因组进化如何被认为与退火的物理现象有关,并描述了基因组可以说是表现出类似的信息熵的意义。作为这些想法的直接应用,我们分析了海洋微生物基因组中转座子随海洋深度的变化,预测了与最近使用宏基因组调查观察结果一致的趋势。

英文摘要:

The biological world, especially its majority microbial component, is strongly interacting and may be dominated by collective effects. In this review, we provide a brief introduction for statistical physicists of the way in which living cells communicate genetically through transferred genes, as well as the ways in which they can reorganize their genomes in response to environmental pressure. We discuss how genome evolution can be thought of as related to the physical phenomenon of annealing, and describe the sense in which genomes can be said to exhibit an analogue of information entropy. As a direct application of these ideas, we analyze the variation with ocean depth of transposons in marine microbial genomes, predicting trends that are consistent with recent observations using metagenomic surveys.
