Diversity exists among all kinds of microorganisms. As evolution preceded new kinds of microorganisms appeared. The structural, functional and genetic diversity of any cell represents its evolutionary event. Both culturable and non-culturable (metagenomic) bacteria play a significant role in human welfare. They have multifarious functions, as effective as other synthetic agents applied in agro-ecosystem. The various facets of bacterial diversity are presented in relation to their emergence in agriculture in this volume entitled "Bacterial Diversity in Sustainable Agriculture"
