“…1a, b). The most dramatic effect was seen by the Pantoea isolate EA106, producing 53.4 % siderophore units post 24 h. It is speculated that the microbial siderophore production influences the plant growth by influencing the Fe uptake (Dastager et al 2010). Interestingly, EA106 also showed high Fe-siderophore activity upon its association with rice roots (Fig.…”

A natural rice rhizospheric isolate abates arsenic uptake in rice by increasing Fe plaque formation on rice roots. Rice (Oryza sativa L.) is the staple food for over half of the world's population, but its quality and yield are impacted by arsenic (As) in some regions of the world. Bacterial inoculants may be able to mitigate the negative impacts of arsenic assimilation in rice, and we identified a nonpathogenic, naturally occurring rice rhizospheric bacterium that decreases As accumulation in rice shoots in laboratory experiments. We isolated several proteobacterial strains from a rice rhizosphere that promote rice growth and enhance the oxidizing environment surrounding rice root. One Pantoea sp. strain (EA106) also demonstrated increased iron (Fe)-siderophore in culture. We evaluated EA106's ability to impact rice growth in the presence of arsenic, by inoculation of plants with EA106 (or control), subsequently grew the plants in As-supplemented medium, and quantified the resulting plant biomass, Fe and As concentrations, localization of Fe and As, and Fe plaque formation in EA106-treated and control plants. These results show that both arsenic and iron concentrations in rice can be altered by inoculation with the soil microbe EA106. The enhanced accumulation of Fe in the roots and in root plaques suggests that EA106 inoculation improves Fe uptake by the root and promotes the formation of a more oxidative environment in the rhizosphere, thereby allowing more expansive plaque formation. Therefore, this microbe may have the potential to increase food quality through a reduction in accumulation of toxic As species within the aerial portions of the plant.

“…The second method used to confirm and quantify IAA production was high performance liquid chromatography (HPLC) with fluorescence detection (Dastager et al, 2011;Angulo et al, 2014). In order to evaluate specific IAA production, this methodology was applied to the 100 highest indole…”

“…Different species belonging to the Serratia genus are well-known PGPR, and strains have been isolated from the rhizosphere of crops. Plant-associated Serratia improve the health and development of their host plant by several mechanisms such as by producing indole acetic acid (Koo and Cho, 2009;Dastager et al, 2011;George et al, 2013), by fixing nitrogen (George et al, 2013), by 1-aminocyclopropane-1-carboxilate deaminase activity (George et al, 2013), by solubilizing phosphate (Dastager et al, 2011;George et al, 2013), by producing siderophores (Koo and Cho, 2009;Dastager et al, 2011) and by inducing systemic resistance of the host plant (Singh and Jha, 2016). A positive role for Serratia species in growth promotion have been demonstrated on several plant species, including black pepper (Dastager et al, 2011), corn (Koo and Cho, 2009), wheat (Singh and Jha, 2016) and coconut palms (George et al, 2013).…”

Raulí is one of the most emblematic tree species of the Chilean temperate forests. Due to the high quality wood, this tree has been used for furniture and handicrafts manufacturing, which has positioned raulí as one of the most important commercial timber species in Chile. Currently, the international market demands sustainable production system for forest production, more specifically in plantlets production. In this regard, plant growthpromoting rhizobacteria (PGPR) inoculants may enhance the growth and survival of plantlets in nurseries, which means an increase in the effectiveness of replanting operations. Therefore, the aim of the present study was to isolate, characterize and screen rhizosphere-associated bacteria with PGPR potential, isolated from raulí that growth in volcanic soils in southern Chile. A total of 1,261 bacterial strains were isolated from different volcanic soils. Out of 1,261 isolates, 100 were selected based on their high levels of indole acetic acid (IAA) production. These isolates were then subjected to screening for 1-aminocyclopropane-1-carboxylic acid deaminase activity, and their ability to fix nitrogen was determined. From the 100 selected isolates, 7 were chosen for producing the highest amount of IAA to continue with genetic characterization based on their 16S rRNA gene sequences. These 7 isolates were characterized as members of the Serratia genus and were used to develop multi-strain inoculant mixtures. Later, a nursery study followed to determine the effect of inoculation with the Serratia strains on the growth of RA88 raulí clone plantlets. The nursery experiment demonstrated that Serratia strains have the potential to increase the root collar diameter, height, relative chlorophyll content, biomass and nitrogen content of raulí plantlets. The study concluded, that Serratia strains have the potential to be used as biofertilizers to increase plant growth in nursery conditions.

“…They help in fixing atmospheric nitrogen, provide nutritional uptake by solubilizing phosphate and producing biologically active molecules which influence plant growth (Arshad and Frankenberger, 1992).Studies has shown that for PGPR to be utilized in crop production, it must be able to exert it effects in either one of these three ways; firstby providing the plant with growth-promoting compounds (Glick 1995), secondly by uptake of certain essential nutrients such as phosphorus, nitrogen, sulfur, calcium and magnesium, (Bashan and Levanony 1990;Belimov and Dietz 2000;Cakmakci et al 2006) and thirdly by averting plants diseases (Khan et al 2002;.The demonstration of increased growth and productivity of many commercial crops including maize (Sandhya et al, 2010), rice (Ashrafuzzaman et al, 2009), black pepper (Dastager et al, 2010), wheat (Cakmakcı et al, 2007), sugarcane (Sundara et al, 2002), cotton (Anjum et al, 2007), Banana (Mia et al, 2010), and cucumber (Maleki et al, 2010) and those seen in Tables 2 has given credit to this biotechnology. There has been public call for possible exploitation of their role in biofertilizers production, microbial rhizoremediation and biopesticides synthesis (Adesemoye et al, 2008).…”

Plant growth promoting rhizobacteria (PGPR) involves the utilization of large array of soil bacteria to improve yield and plant growth. As free living and symbiotic rhizobacteria, PGPR colonizes extracellular and/or intracellular rhizoenvironment in search for carbon source while indirectly aiding plant growth. In the past few decades, focus has been on developing a biosafety agro base approach void of continuous burden on soil micro flora as a result of agrochemical application. However, with clear understanding of PGPR mechanisms of action; (i) biofertilization (ii) biostimulation (iii) and biocontrol, it create more hope on the possibility of curbing food insecurity, clean environmental sustenance and lower public health risk. Seeds or soil application of PGPRs inoculant enhances directly phosphates solubilization, atmospheric nitrogen fixation and secretion of plant hormones (indole acetic acid, gibberellins, cytokinins and ethylene) needed for growth and adaptation in stressed environment. As soil pathogen consistently rival the roles of these organisms, they (PGPRs)have developed over time wide spectrum of strategies in the form of systemic resistance, iron, space and nutrient competition, antibiotics synthesis, lytic acid production and hydrogen cyanide for efficient food productivity. In view of this, the review widen our scope on the use of PGPR as bioinoculant in sustainable agro practice and to serve as a wakeup call for it reception and implementation in the tropics where paucity of data on it use has long prevailed.
