Life in earth – the root microbiome to the rescue?

Manipulation of the soil microbiome holds great promise for
contributing to more environmentally benign agriculture, with
soil microbes such as Pseudomonas promoting plant growth
and effectively suppressing pathogenic microorganisms. Nextgeneration sequencing has enabled a new generation of
research into soil microbiomes, presenting the opportunity to
better understand and exploit these valuable resources. Soil
bacterial communities are both highly complex and variable,
and contain vast interspecies and intraspecies diversity, both of which respond to environmental variation. Therefore, we propose that a combination of whole microbiome analyses with in-depth examination of key microbial taxa will likely prove the most effective approach to understanding rhizosphere microbial interactions. This review highlights recent efforts in this direction, based around the important biocontrol bacterium Pseudomonas fluorescens.
