ABSTRACT
Metagenomics refers to the genomic assemblages of microorganisms isolated directly from their environment, without the need for prior culturing under laboratory conditions. The vector-enabled metagenomics approach has been employed to study the highly polyphagous and mobile nature of the whitefly vector, combined with the capability of metagenomics to discover novel viruses without relying on sequence similarity to known viruses. As a consequence, two approaches to weed management can be developed using metagenomic techniques: 17.7.1 Countless screening assays specific to weed management can be developed using metagenomic clone libraries. The data confirm the powerfulness of the pyrosequencing approach, which represents a promising new tool to better understand the natural distribution of an essential group of soil microorganisms, such as fungi. The rhizosphere region of crop plants represents interesting bio-resources; their intense interaction with microorganisms is only partly understood. Viral metagenomics has been used to characterize viral communities present in the individual plants.
