Isotope probing shows soil is packed with dormant viruses lying in wait

Article excerpt

A single gram of soil contains between 10 million and 1 billion viruses. Most of those viruses do not infect plants, animals or people, but they do target bacteria and other microbes. Because of their influence on microbial communities, viruses can affect nutrient cycling and soil health. Understanding how they behave is therefore crucial to supporting agriculture, food production and water quality.
