The genus Bacillus is one of the predominant bacterial genera found in soil, and several species of this genus have been reported from diverse ecological niches. Endowed with tremendous genetic and metabolic diversity, Bacillus spp. serve multiple ecological functions in soil ecosystem from nutrient cycling to conferring stress tolerance to plants. Members of the genus Bacillus are known to have multiple beneficial traits which help the plants directly or indirectly through acquisition of nutrients, overall improvement in growth by production of phytohormones, protection from pathogens and other abiotic stressors. This functionally versatile genus is one of the most commercially exploited bacteria in the agro-biotechnology industry. Still its potential has not been realized sufficiently and requires an emphasis towards translating the relevant technologies from laboratory to land for the benefit of mankind.
