“…Most of the commercially developed PGPR belong to the genus Bacillus, and among the genus, strains of B. subtilis have been recognized as PGPR, mainly because of their disease reducing ability and resistance to environmental stresses due to spore forming nature. The importance and preference for the Bacillus species in field applications is of late getting attention (Ghosh et al, 2003;Liu et al, 2006;Trivedi et al, 2008;Trivedi and Pandey, 2008b;Pandey et al, 2011;Zhao et al, 2011).…”

On-farm inoculation trials have been conducted to evaluate the potential of Bacillus subtilis NRRL B-30408 in respect of plant growth promotion, for two consecutive years, under rainfed conditions at a mountain location in the Indian Himalayan Region (IHR). For this, one cereal (Oryza sativa) and two millets (Eleusine coracana and Echinochloa frumentacea), were used as test crops. Observations were recorded in terms of plant growth, yield, chlorophyll content, and root colonization by various groups of microorganisms. Positive influence of bacterial inoculation on all the three crops, statistically significant in case of most parameters examined as compared to untreated controls, was recorded in both the years. There was a significant increase in chlorophyll concentration in leaves of inoculated plants. While the bacterial inoculation stimulated the free living bacterial and actinomycetes populations in the rhizosphere, the fungal population was somewhat suppressed; indicative of the antifungal property of the inoculant. The treatment also enhanced the colonization of arbuscular mycorrhizae (AM), and the endophytes associated with the roots. In conclusion, the plant growth promotion, recorded as a result of microbial inoculation, is attributed to the microbial shift in the native microflora of the rhizosphere. Based on the results of this field study, B. subtilis NRRL B-30408 can be proposed as an efficient bioinoculant for the hill crops, grown under rainfed conditions of the mountain ecosystem. The main aim of this study was on farm demonstration of the microbe based technology with peoples' participation, with a view of adoption of the technology by the farmers.

“…The enzyme 1-aminocyclopropane-1-carboxylate deaminase (ACCD) is widely spread in bacteria (Belimov et al, 2001, Ghosh et al, 2003Ma et al, 2003;Dey et al, 2004;Glick, 2005;Hontzeas et al, 2005;Blaha et al, 2006;Madhaiyan et al, 2006;Duan et al, 2009). It cleaves ACC, the immediate precursor of ethylene in plants and convert into ammonia and α-ketobutyrate (Glick et al, 1998).…”

“…Importantly the PGPR containing 1-aminocyclopropane-l-carboxylic acid (ACC) deaminase were considered to effectively facilitate the early growth of plants, especially under stressful conditions such as flooding, heavy metals, phytopathogens, drought and high salinity (Grichko et al 2001;Belimov et al 2005;Mayak et al 2004). Ethylene is an important phytohormone connected with fruit ripening, however, overproduction of ethylene under stressful conditions can result in the inhibition of plant growth or death, especially for seedlings (Glick et al 1997 andGhosh et al 2003). PGPR containing ACC deaminase can hydrolyze ACC, the immediate precursor of ethylene, to α-ketobutyrate and ammonia, leading to reduction in ethylene levels, thus promoting plant growth (Glick et al 1998).…”

Salinity is one of the most relevant abiotic factor limiting crop yield and its net primary productivity. In addition, salinity induces an increased stress ethylene synthesis in plants which, in turn, exacerbate the responses to the stressor. Bacterial single or co-inoculation effect was tested using previously characterized plant growth promoting (PGP) bacteria Brevibacterium iodinum RS16 and Methylobacterium oryzae CBMB20 on maize and sorghum-sudan grass hybrid under different concentrations of NaCl. Non-inoculated maize and sorghum-sudangrass hybrid showed 33.4% and 20.0% reduction in seed germination under highest NaCl (150 mM) level tested. However, under the same NaCl concentration, co-inoculation with B. iodinum RS16 and M. oryzae CBMB20 PGP strains increased the seed germination in maize (16.7%) and sorghumsudangrass hybrid (4.4%). In Gnotobiotic growth pouch experiments conducted for maize and sorghumsudangrass hybrid, co-inoculation of PGP B. iodinum RS16 and M. oryzae CBMB20 mitigated the salinity stress and promoted root length by 22.9% and 29.7%, respectively. Thus the results of this study could help in development of potential bioinoculants that may be suitable for crop production under saline conditions.
