报告摘要:
Despite their tiny size, viruses are by far the most abundant “life-forms” on Earth, and exist wherever life is found. If stretched end-to-end, the estimated 1030 viruses in the ocean, would span farther than the nearest 60 galaxies. Viruses probably infect all living organisms from plankton to whales, thereby influencing the composition of marine communities, causing disease in organisms, and driving nutrient and energy cycling. Every second there are about 1023 viral infections in the ocean, which potentially can introduce new genetic information into an organism, and thereby drive the evolution of the viruses and the organisms they infect. Our understanding of the impact of viruses on global systems continues to unfold, overthrowing the paradigm that viruses are minor players global processes.
病毒,作为最简单的生命形式,几乎无处不在。每一秒钟约有1023个病毒侵染在海洋中发生,从而对生命体的新基因信息产生影响,推动病毒和它们所侵染的生命体的进化及生态过程,并最终影响到全球变化。
