“…For example, the inoculation of Pseudomonas fluorescens in a grass species was able to aid in the decomposition of the increased plant C inputs associated with eCO 2 , while promoting plant productivity (Nie et al 2015). In another study, the best performing PGPB under drought stress conditions was selected from field-grown sorghum (Silva et al 2018). Also, under drought stress conditions, the application of N fixing bacteria reduced the requirement of chemical fertilizer and enhanced macro and micronutrient concentrations in Medicago scutellata (Shabani et al 2015).…”

“…Even in poor soil strata, a mixture of five PGPB was found to have a significant impact on nutrient availability, alongside with the capacity to rehabilitate the soil (Radhapriya et al 2018). With this strategy, it is possible to perform a pre-selection of the PGPB to optimize plant growth for each specific field condition (Silva et al 2018). This might be optimal for small farming conditions, but in a wider scale, challenges still reside regarding stability and economic feasibility (Lobo et al 2018).…”

Background Global climate is changing more rapidly than ever, threatening plant growth and productivity while exerting considerable direct and indirect effects on the quality and quantity of plant nutrients. Scope This review focuses on the global impact of climate change on the nutritional value of plant foods. It showcases the existing evidence linking the effects of climate change factors on crop nutrition and the concentration of nutrients in edible plant parts. It focuses on the effect of elevated CO 2 (eCO 2), elevated temperature (eT), salinity, waterlogging and drought stresses, and what is known regarding their direct and indirect influence on nutrient availability. Furthermore, it provides possible strategies to preserve the nutritional composition of plant foods under changing climates. Conclusions Climate change has an impact on the accumulation of minerals and protein in crop plants, with eCO 2 being the underlying factor of most of the reported changes. The effects are clearly dependent on the type, intensity and duration of the imposed stress, plant genotype and developmental stage. Strong interactions (both positive and negative) can be found between individual climatic factors and soil availability of nitrogen (N), potassium (K), iron (Fe) and phosphorous (P). The development of future interventions to ensure that the world's population has access to plentiful, safe and nutritious food may need to rely on breeding for nutrients under the context of climate change, including legumes in cropping systems, better farm management practices and utilization of microbial inoculants that enhance nutrient availability.

Plant growth-promoting bacteria belonging to the genera <em>Pseudomonas</em> and <em>Bacillus</em> improve the growth of sorghum seedings in a low-nutrient soil

et al. 2021

Background: Deficiency in sorghum growth in ecosystems of low-nutrient soils has been scarcely studied. This soil deficiency can be overcome by the addition of plant growth-promoting bacteria which increase sorghum growth. Questions and/or Hypotheses: indole acetic acid (IAA) producing and phosphate solubilizing bacteria can promote sorghum growth under nutritional stress. Studied species: Sorghum bicolor (L.) Moench. Study site and dates: Mexico City, 2018. Methods: Of the twelve bacterial strains utilized, three produce IAA (group BI), two strains produce IAA and siderophores (BIS group), four strains produce IAA and solubilize phosphate (BIP group), and three strains produce IAA, solubilize phosphate, and produce siderophores (BIPS group). Hydroponic bioassays and low-nutrient soil bioassay were used. Results: In hydroponic bioassays, for BI and BIS groups, five strains significantly increased the growth parameters with respect to the control, and for the BIP and BIPS groups, two strains promoted stem development and shoot dry weight. In a low-nutrient soil bioassay, Pseudomonas sp. BI-1 (from BI group) was the one that presented the highest percentages 32, 48, 140 and 79 % in stem diameter, height and dry weight of the shoot and dry weight of the root, respectively, followed by the P. mohnii BIPS-10 strain (from BIPS group) that exhibited similar results. Conclusions: IAA producing Pseudomonas strains improve the sorghum growth in a low-nutrient soil and suggest thatPseudomonas sp. BI-1 and P. mohnii BIPS-10 could be used as potential bioinoculants for sorghum.

“…Furthermore, Santana et al (2020) showed that Enterobacter sp., Bacillus sp., and Rhizobium sp., isolated from T. spicata , were also able to improve some plant growth and gas exchange parameters in sorghum growing under drought conditions ( Tables 1 , 2 ). Although these bacterial groups have already been shown to be efficient inoculants for sorghum ( da Silva et al, 2018 ; Antunes et al, 2019 ), their ability to attenuate the adverse effects of drought and promote sorghum growth under drought had not been revealed. Interestingly, these T. spicata isolates showed diazotrophic capacity in a culture medium supplemented with up to 1.27 mol L –1 NaCl ( Table 1 ; Fernandes-Júnior et al, 2015 ), which suggests that the beneficial effects of BNF may be supported around the plant environment under water-deficit conditions.…”

Semiarid regions are apparently low biodiversity environments; however, these environments may host a phylogenetically diverse microbial community associated with plants. Their microbial inhabitants are often recruited to withstand stressful settings and improve plant growth under harsh conditions. Thus, plant-associated microorganisms isolated from semiarid and seasonally dry environments will be detailed in the present review, focusing on plant growth promotion potential and the microbial ability to alleviate plant abiotic stress. Initially, we explored the role of microbes from dry environments around the world, and then, we focused on seasonally dry Brazilian biomes, the Caatinga and the Cerrado. Cultivable bacteria from semiarid and seasonally dry environments have demonstrated great plant growth promotion traits such as plant hormone production, mobilization of insoluble nutrients, and mechanisms related to plant abiotic stress alleviation. Several of these isolates were able to improve plant growth under stressful conditions commonly present in typical semiarid regions, such as high salinity and drought. Additionally, we highlight the potential of plants highly adapted to seasonal climates from the Caatinga and Cerrado biomes as a suitable pool of microbial inoculants to maintain plant growth under abiotic stress conditions. In general, we point out the potential for the exploitation of new microbial inoculants from plants growing in dry environments to ensure a sustainable increase in agricultural productivity in a future climate change scenario.
