Abstract

Drought stress affects plant growth and causes significant issues in meeting global demand for food crops and fodder. Drought can cause physiological, physicochemical, and morphological changes in plants, which negatively affects plant growth and productivity. To combat this under the increasing global threat of water shortage and rapid population expansion, it is crucial to develop strategies to meet global food demands. Plant growth-promoting rhizobacteria (PGPR) may provide a safe solution to enhancing crop yields through various mechanisms. These soil bacteria can provide drought tolerance to crop plants, allowing them to survive and thrive in water-scarce conditions. Productions of phytohormones, free radical-scavenging enzymes, and stress-combating enzymes that can increase tolerance to drought-induced stress are key features of plant-associated microbial communities. This review summarizes the beneficial properties of microbes that help plants tolerate water scarcity and highlights the bacterial mechanisms that enhance drought tolerance in plants.

Dynamic interplay among soil nutrients, rhizosphere metabolites, and microbes shape drought and heat stress responses in summer maize
2024, Soil Biology and Biochemistry
The frequent occurrence of extreme weather events has brought forth significant challenges to the future development of agriculture, and it is imperative to enhance crop resilience to extreme events. In this study, the 16S rRNA sequences and internal transcribed spacers were examined, and non-targeted metabolomics was conducted to characterize variations in summer maize crop rhizosphere microbial diversity and metabolites under drought (DS), heat (HS), and combined drought and heat stress (DHS). After 15 days of beginning stress, plants treated with DHS exhibited a 51.7% reduction in aboveground biomass and 34.5% reduction in root biomass compared to the control. Further, under DHS, Gemmatimonadota had a greater relative abundance in contrast to when exposed to either DS or HS, under DS, Actinobacteriota (16.1%) had the highest relative abundances. When exposed to HS in contrast to the other two stress treatments, the Basidiomycota (31.2%) relative abundance became significantly elevated. Metabolites, consisting of phenol ethers, fatty acyls, organooxygen compounds, allyl-type 1,3-dipolar organic molecules and organic nitro compounds, were differentially abundant across different treatments. Pathway analysis highlighted the up-regulation of ABC transporters, penicillin/cephalosporin biosynthesis, and valine/leucine/isoleucine biosynthesis pathways when exposed to either DHS compared to DS or HS. Overall, these findings suggest that DHS would stimulate the secretion of L-valine by the roots, thereby facilitating the recruitment of Gemmatimonadota and improving nitrate and ammonium absorption by roots under DHS. In brief, the results offer significant insights into the interactions between microbes and plants, as well as the potential to harness beneficial microbial communities to improve maize resilience and productivity under different types of abiotic stress.
Role of nanofertilizers in improving abiotic stress tolerance
2024, Nanofertilizer Delivery, Effects and Application Methods
Nanofertilizers (NFs) are materials on the nanometer scale (1–100 nm) containing macro and/or micronutrients. They possess unique physical and chemical characteristics and thus have great potential to deliver nutrients to plants with high efficiency and low cost. Abiotic stresses like drought, salinity, heat, and heavy metals are crucial limitations that greatly affect the productivity of plant crops. For the management of abiotic stress and to overturn crop productivity loss caused by abiotic stress in plant crops, the NFs are applied to protect plants and enhance nutrient use efficiency and agricultural sustainability. This chapter overviews, discusses, and reports on the potential application and use of NFs to enhance the mitigating capabilities of plants under abiotic stresses. In addition, it covers the toxic effects of nanomaterials on crops and discusses the need to develop future greener and ecofriendly nanoparticle-based fertilizers to combat the harmful impact of abiotic stresses on crop productivity.
A newly isolated Bacillus pumilus strain SH-9 modulates response to drought stress in soybean via endogenous phytohormones and gene expression (Daegu, South Korea)
2023, Plant Stress
Drought stress hampers plant growth and productivity. Some microorganisms mitigate stress in plants; however, the molecular mechanism by which they interact with plants in mitigating stress remains unknown. This study aimed to determine the mechanism by which plant growth–promoting rhizobacteria modulate drought stress in soybean. Results indicated that B. pumilus SH-9 (SH-9) produced indole acetic acid and siderophore, and had capacity for phosphate solubilization. The test for polyethylene glycol 6000 (PEG) tolerance, showed that SH-9 could withstand high PEG concentration (up to 30 %). The isolate was identified a B. pumilus strain using a 16 s ribosomal DNA gene sequence. Inoculation of soybeans with SH-9 enhanced soybean plant growth and biomass by 20 %, even under high drought stress. This was due to a reduction of the endogenous phytohormone (abscisic acid) and upregulation of the antioxidant defense system (SOD, POD, APX, and GSH) by SH-9. Furthermore, the transcription factors GmDREB2, GmbZIP1, and GmNCED3 were involved. Inoculation with SH-9 also improved physio-morphological characteristics such as biomass, chlorophyll, seedling length, and relative water contents in the stressed plant. Overall, the findings of this study indicated that SH-9 enhances plant growth by promoting phosphate solubilization, siderophore, and exopolysaccharides. We, therefore, conclude that SH-9 is a drought-tolerant variant that can improve plant growth even under drought stress via modulation of expression of the phytohormone gene, and antioxidant profile.
Native rhizobacteria suppresses spot blotch disease, improves growth and yield of wheat under salt–affected soils
2023, Plant Stress
The simultaneous occurrence of biotic and abiotic stresses affects the performance of the crops in salt–affected agroecologies. The plant–microbe interaction with effective rhizobacteria can effectively manage these stresses. This study characterized the biocontrol, plant growth promotion, and responsiveness of rhizobacteria in wheat under salt-affected soils. Out of the 184 rhizobacteria isolates, the 20 isolates showed 41–72% growth inhibition of fungal phytopathogens of seedling blight of wheat (Fusarium sp), head blight of wheat (Fusarium oxysporum), onion molds (Penicillium sp and Aspergillus sp), root rot of wheat (Rhizoctonia solani), ear rot of corn (Aspergillus sp.) and spot blotch of wheat (Bipolaris sorokininana). The potent three rhizobacterial isolates identified as close neighbours of Bacillus amyloliquefaciens strain TA124, B. subtilis strain SB67 and B. subtilis strain BJ171 caused 65.5–71.1% growth inhibition of B. sorokiniana. The extracellular organic acid, siderophore, and chitinase enzymes played a significant role in rhizobacterial performance for fungal growth inhibition; and P and Zn solubilization in growth media. The foliar spray of bioformulation aids 15–20% reduction in the B. sorokiniana disease severity. The rhizobacterial responsiveness to the dual inoculation through seed treatment and foliar spray was 12.6–51, 15.8–46.3, and 13.2–148.1% for grain yield, P uptake, and disease suppression, respectively. The changes caused by rhizobacterial bioformulation in soil (Olsen's–P and microbial biomass carbon) and plant (proline, malondialdehyde, peroxidase, and Na⁺/K⁺ratio) explained 85% variability in the yield, P nutrition, and disease severity. Therefore, native rhizobacteria with biocontrol and plant growth-promoting capabilities can be an effective option for managing multiple stresses of crops in salt–affected agroecologies.
Contrasting effects of different organic amendments on the microbial responses to extreme temperature changes
2023, Geoderma
Soil organic amendments can change microbial communities, potentially impacting their resilience to environmental stresses and, consequently, their transformation of soil carbon and nitrogen. While several studies have investigated the impact of a few organic amendments on microbial resilience to stresses in the form of absolute change in environmental conditions, the potential stress effects of different rates of change have received much less attention. The rate of change in environmental properties such as temperature may induce different microbial stress responses, given the reliance of microbial defensive mechanisms on time-dependent signalling and activation processes. In this research, we explored the relevance of the rate of temperature change as a microbial stressor and evaluated the potential use of organic amendments in steering soil ecological response. We monitored the changes in microbial properties and concentrations of different carbon and nitrogen fractions to temperature change treatments of 2.5 and 30 °C/d after the application of three commonly available rural organic amendments to a podzol soil in a laboratory incubation study. Results showed significant effects of the temperature treatments on bacterial and total microbial DNA concentrations, as well as on dissolvable and insoluble carbon and nitrogen ratios regardless of the organic amendment treatment. Temperature impacts on respiration rates, priming rates and the concentration of soil hot water extractable carbon and nitrogen differed depending on the organic amendment treatment. Results demonstrated that compost-amended soils were least sensitive to the temperature treatments, while grasses and fermented grasses treatments were generally more sensitive while showing opposite responses. Our findings indicate that organic amendments might be utilized to manipulate the impact of environmental stresses on soil carbon and nitrogen concentrations, and highlight the need for future research to investigate the relevant ecological properties and mechanisms.
Exogenous Streptomyces spp. benefit naked oat growth under dry farming conditions by modifying rhizosphere bacterial communities
2023, Applied Soil Ecology
Manipulation of rhizosphere microbiota is an effective strategy to facilitate crop growth in dry farming systems. Actinobacteria, such as Streptomyces spp., have the potential to alleviate plant damage induced by drought stress. However, whether exogenous actinobacteria can promote naked oat (Avena nuda L.) growth in drylands by reshaping rhizosphere bacterial community structure is still unclear. This study evaluated the effects of S. albidoflavus T4 and S. pactum Act12 on the growth and yield of naked oat through a two-year field experiment conducted in Taigu, Shanxi Province, China. Streptomyces-mediated shifts in rhizosphere bacterial diversity and community composition were analyzed based on 16S ribosomal RNA gene sequencing. Both T4 and Act12 inoculation improved plant growth and grain yield by 21.5 %–27.4 % compared with the uninoculated control. Despite no significant changes in the alpha diversity of rhizosphere bacteria, their community composition varied in different patterns following inoculation. In T4-treated soils, there were increased proportions of Chloroflexi (rare phylum), Stenotrophomonas (abundant genus), and Acidovorax (moderate genus), along with a decreased proportion of Polycyclovorans (moderate genus). These differential taxa were closely related to increased soil available phosphorus and potassium contents as well as alkaline phosphatase activity, thereby contributing to plant growth. Act12-treated soils showed increased proportions of Lachnospiraceae_NK4A136 (abundant genus), Pantoea (rare genus), and Kluyvera (rare genus), in contrast to the decreasing trend of Microvirga (moderate genus). These differential taxa were mainly associated with enhanced soil sucrase and leaf catalase activities, which indirectly increased plant biomass and grain yield. The findings demonstrate that inoculation with S. albidoflavus T4 and S. pactum Act12 conveys benefits to naked oat growth under dry farming conditions as an indirect consequence of alterations in key taxa abundance in rhizosphere microbiota coupled with changes in soil chemical environment and plant antioxidant activity.
