The global scale of land salinization has always been a considerable concern for human livelihoods, mainly regarding the food-producing agricultural industries. latest update suggested that perpetual salinity problem claimed up to 900 million hectares worldwide, inducing stress among salt-sensitive crops and ultimately reducing productivity yield. Moreover, with constant growth population, sustainable solutions are vital ensure food security social welfare. Despite that, current method crop augmentations via selective breeding genetic engineering only resulted in mild success. Therefore, using biological approach halotolerant plant growth-promoting bacteria (HT-PGPB) as bio-inoculants provides promising enhancement strategy. HT-PGPB proven capable forming symbiotic relationship host by instilling induced tolerance (IST) multiple traits (PGP). Nevertheless, mechanisms prospects application glycophytic rice remains incomprehensively reported. Thus, this review describes plausible strategy halophyte-associated future catalyst production salt-dominated aims meet Sustainable Development Goals (SDGs) zero hunger.

With the increasing shortage of land resources and people's attention to ecological environment, application microbial fertilizer with natural soil microorganisms as main component has attracted in saline agriculture. In this study, two salt-tolerant strains, YL07 (Bacillus atrophaeus) YL10 (Planococcus soli), were isolated from maize (Zea mays L.) rhizosphere a saturated conductivity (ECe) 6.13 dS/m pH 8.32 (Xinjiang, China). The effects B. atrophaeus WZYH01 (YL07) Planococcus soli WZYH02 (YL10) on growth development under salt stress (ECe = 5.9 dS/m) further studied. results showed that compared uninoculation, inoculation significantly improved performance, biomass yield, antioxidant levels stress, effect was more prominent than WZYH01. Moreover, protected by regulating plant hormone [IAA abscisic acid (ABA)] nutrient acquisition. addition, tested strains most efficient for health, content K+ accompanied an effective decrease Na+ tissues. transcription tolerance genes (ZMNHX1, ZMNHX2, ZMHKT, ZMWRKY58, ZMDREB2A) inoculated also dramatically higher specified uninoculated maize. conclusion, can alleviate harmful crop growth, thereby promoting sustainable agricultural development.

Micronutrient deficiency is a serious health issue in resource-poor human populations worldwide, which responsible for the death of millions women and underage children most developing countries. Zinc (Zn) malnutrition middle- lower-class families rampant when daily calorie intake staple cereals contains extremely low concentrations micronutrients, especially Zn Fe. Looking at importance problem, present investigation aimed to enhance growth, yield, nutrient status, biofortification wheat crop by inoculation native zinc-solubilizing Bacillus spp. conjunction with soil-applied fertilizers (NPK) zinc phosphate saline soil. In this study, 175 bacterial isolates were recovered from rhizosphere grown eastern parts Indo-Gangetic Plain India. These further screened solubilization potential using sparingly insoluble carbonate (ZnCO 3 ), oxide (ZnO), {Zn (PO 4 ) 2 } as source under vitro conditions. Of isolates, 42 found solubilize either one or two all three compounds, subsequently, these identified based on 16S rRNA gene sequences. Based zone halo diameter, efficiency, amount solubilized zinc, six strains, i.e., altitudinis AJW-3, B. subtilis ABW-30, megaterium CHW-22, licheniformis MJW-38, Brevibacillus borstelensis CHW-2, xiamenensis BLW-7, shortlisted pot- field-level evaluation crop. The results clearly indicated that inoculants not only increase plant growth but also yield attributes. Furthermore, enhanced available nutrients microbial activity pot experiments. It was observed application CHW-22 significantly increased content straw grains along other (N, P, K, Fe, Cu, Mn) followed MJW-38 compared inoculants. By large, similar observations recorded field Interestingly, comparing use efficiency (NUE) wheat, showed their enhancing NUE greater way, confirmed correlation principal component analyses. This study apparently provides evidence upon chemical degraded soil both nethouse

Abstract Halotolerant rhizobacteria, which are able to withstand higher concentrations of salts, useful for conferring salinity tolerance agricultural crops and improving soil fertility through their different activities. Among various mechanisms, the improvement in enzyme activities they bring about production extracellular enzymes is crucial. Soil responsible supplying nutrients plants under stressed conditions. In current study, halotolerant plant growth‐promoting rhizobacteria ( Bacillus Acinetobacter ) species were examined individually combination compare efficiency with improve naturally salt‐affected The microbial consortium caused a significant increase urease (1.15‐fold), dehydrogenase (14%), acid phosphatase (78%), alkaline (52%) activities, led shoot N (42%), grain (98%), straw P (40%), (44%) comparison uninoculated control. addition, application maize Zea mays L.) seeds considerable improvements height (70%), cob length (67%), yield (69%), stomatal conductance (17%), water‐use (96%), photosynthetic rate (22%), weight (1.63‐fold), transpiration (1.2‐fold). Moreover, inoculation resulted reduction leaf Na + (38%) content, as evidenced by reduced antioxidant (i.e., catalase [59%], superoxide dismutase [37%], glutathione reductase [45%], ascorbate peroxidase [19%], malondialdehyde [53%]) after application. conclusion, rhizobacterial alleviated negative impacts on growth nutrient acquisition stress.

Plant growth-promoting rhizosphere bacteria (PGPR) are increasingly considered as highly efficient bioagents. They confer for instance better salt tolerance to host plants while improving soil enzyme activities and microbiome diversity, which indicators of biological health fertility. Here, the aim was investigate efficiency native from saline Hordeum marinum, in alleviating adverse effects salinity this facultative halophyte with fodder potential. Following identification characterization capacity vitro plant growth promoting potential, strain Bacillus pumilus, selected its ameliorative on H. marinum when cultivated under NaCl (200 mM) a greenhouse experiment. Salinity significantly restricted growth, induced oxidative stress disturbed mineral nutrition whereas inoculation B. pumilus restored leaf elongation rate dry weight. Similarly, highest accumulation K+, N P were observed inoculated challenged salinity. This concomitant reduced MDA H2O2 levels, thereby preventing damage stress. Furthermore, also overcame impact via indirect mechanisms by activating enzymes (dehydrogenase, β-glucosidase acid phosphatase) microbial biomass C production. Overall, our data further highlight environmental significance microorganisms inhabiting extreme environments like sabkhas promising agents approaches aiming at rehabilitation productivity salinity, due their beneficial effect both rhizosphere.
