One face looks at the plant root, the other sees the soil. The ears and the nose sense the other gods around and the mouths are wide open, swallowing as much as they can, and as described in Chapter 11, they also are busy talking. These faces may as well represent Hygieia (the Greek god of Health and Hygiene, the prevention of sickness and the continuation of good health) and Morta (the Roman god of death) for rhizosphere microbes can be beneficial, and promote plant growth and well being (Chapter 12) or detrimental, causing plant sickness and death (Chapter 13). It can be argued that many rhizosphere microbes are “neutral”, faceless saprophytes that decompose organic materials, perform mineralization and turnover processes. While most may not directly interact with the plant, their effects on soil biotic and abiotic parameters certainly have an impact on plant growth. Maybe they are Janus’ feet, the unsung heroes of the rhizosphere.
