“…Sarcheshmehpour et al (2013) reported a positive effect of plant-growth-promoting rhizobacteria under drought stress on the growth and nutrition of pistachio seedlings. Similar results have also been reported by Rana et al (2015) on the positive effects of growth-promoting rhizobacteria on rice and wheat.…”

The study was conducted to investigate the effect of growth-promoting bacteria (Azotobacter vinelandii = A, Pantoea agglomerans + P. putida = P, combined A + P, control) on the germination, growth and nutrient uptake of Onobrychis sativa L. under drought stress (field capacity (FC), 0.7 FC, 0.4 FC). The results showed that the highest and lowest germination rate (GR) was related to the P and control treatments in FC level, respectively. The maximum root and shoot length at the FC level was related to the treatment A. In the A + P treatment, the maximum shoot dry weight was measured in 0.7 FC level. The lowest root dry weight was also related to the A + P treatment in the FC level. Bio-fertilizers had the maximum impact in increasing the nutrients uptake in 0.7 FC and FC levels. The fertilizers in 0.7 FC and FC levels increased the plant traits and played no significant role in mitigating the effects of drought stress. ARTICLE HISTORY

“…1). Therefore, microorganisms can be used to enhance the accumulation of micronutrients in the grains of staple cereal crops; this has been successful in rice and wheat (Mader et al 2011;Prasanna et al 2016;Rana et al 2012Rana et al , 2015Singh et al 2017a, b, Singh et al 2018, Singh et al 2020Vaid et al 2014;Zhang et al 2012a, b). However, its potential is still to be explored across other crops, ecologies, and farming systems.…”

Micronutrients are essential factors for human health and integral for plant growth and development. Among the micronutrients, zinc (Zn) and iron (Fe) deficiency in dietary food are associated with malnutrition symptoms (hidden hunger), which can be overcome through biofortification. Different strategies, such as traditional and molecular plant breeding or application of chemical supplements along with fertilizers, have been employed to develop biofortified crop varieties with enhanced bioavailability of micronutrients. The use of microorganisms to help the crop plant in more efficient and effective uptake and translocation of Zn and Fe is a promising option that needs to be effectively integrated into agronomic or breeding approaches. However, this is less documented and forms the subject of our review. The major findings related to the mobilization of micronutrients by microorganisms highlighted the significance of (1) acidification of rhizospheric soil and (2) stimulation of secretion of phenolics. Plantmicrobe interaction studies illustrated novel inferences related to the (3) modifications in the root morphology and architecture, (4) reduction of phytic acid in food grains, and (5) upregulation of Zn/Fe transporters. For the biofortification of Zn and Fe, formulation(s) of such microbes (bacteria or fungi) can be explored as seed priming or soil dressing options. Using the modern tools of transcriptomics, metaproteomics, and genomics, the genes/proteins involved in their translocation within the plants of major crops can be identified and engineered for improving the efficacy of plant-microbe interactions. With micronutrient nutrition being of global concern, it is imperative that the synergies of scientists, policy makers, and educationists focus toward developing multipronged approaches that are environmentally sustainable, and integrating such microbial options into the mainframe of integrated farming practices in agriculture. This can lead to better quality and yields of produce, and innovative approaches in food processing can deliver cost-effective nutritious food for the undernourished populations.

“…Among them, plant growth-promoting (PGP) bacteria are either rhizospheric or endophytic and influence plant growth through multiple PGP traits such as nitrogen fixation, production of growth hormones, siderophores and solubilization of Zn, P and K, which are of great importance (Bhattacharyya and Jha 2012 ). Currently, few reports are available for such PGP microbial communities involving genera such as Bacillus , Providencia , Brevundimonas , Ochrobactrum , Azotobacter and Anabaena in enhancing the mineral density of wheat, rice, maize and chickpea (Rana et al 2012a , b , 2015 ; Khalid et al 2015 ; Prasanna et al 2015 ). However, there are no reports on PGP actinobacteria.…”

Plant growth-promoting actinobacteria on chickpea seed mineral density: an upcoming complementary tool for sustainable biofortification strategy

et al. 2016

The present study was evaluated to test the potential of plant growth-promoting actinobacteria in increasing seed mineral density of chickpea under field conditions. Among the 19 isolates of actinobacteria tested, significant (p < 0.05) increase of minerals over the uninoculated control treatments was noticed on all the isolates for Fe (10–38 %), 17 for Zn (13–30 %), 16 for Ca (14–26 %), 9 for Cu (11–54 %) and 10 for Mn (18–35 %) and Mg (14–21 %). The increase might be due to the production of siderophore-producing capacity of the tested actinobacteria, which was confirmed in our previous studies by q-RT PCR on siderophore genes expressing up to 1.4- to 25-fold increased relative transcription levels. The chickpea seeds were subjected to processing to increase the mineral availability during consumption. The processed seeds were found to meet the recommended daily intake of FDA by 24–28 % for Fe, 25–28 % for Zn, 28–35 % for Cu, 12–14 % for Ca, 160–167 % for Mn and 34–37 % for Mg. It is suggested that the microbial inoculum can serve as a complementary sustainable tool for the existing biofortification strategies and substantially reduce the chemical fertilizer inputs.
