Global Threat

In the context of the current climate change and increasing population scenarios, waterlogging stress in plants represents a global threat to sustainable agriculture production. Plant-growth-promoting rhizobacteria and biochar have been widely reported to mitigate the effects of several abiotic stresses. Hence, in the present study, we examined the effect of the rhizobacterium Rhodobacter sphaeroides KE149 and biochar on soybean plants subjected to sufficient water supply and waterlogging stress conditions. Our results revealed that KE149 and biochar inoculation significantly improved plant morphological attributes, such as root length, shoot length, and fresh biomass. The biochemical analysis results showed that the two treatments determined a significant drop in the levels of endogenous phytohormones (such as abscisic acid) under normal conditions, which were considerably enhanced under waterlogging stress. However, the jasmonic acid content increased with the application of biochar and KE149 under normal conditions, and it considerably decreased under waterlogging stress. Moreover, proline, methionine, and aspartic acid were significantly increased, whereas the phenolic and flavonoid contents were reduced with the application of the two treatments under waterlogging stress. These results suggest that the application of KE149 and biochar can be a safe biological tool with which to improve the physiology and productivity of soybean plants exposed to waterlogging stress.

Utilization of ultisols in Southeast Sulawesi may be approached by inoculating viable arbuscular mycorrhizal fungi (AMF) exposing plant growth-promoting activities to the growth of native economical plants. This study investigated a combination of AMF and liquid organic fertilizers from coconut husks to improve the growth of soybean plants grown on ultisols as one of the potential marginal soils in the region. The coconut husk served as an abundant, cheap, yet potential source for the preparation of liquid organic fertilizers. This study used two factorial design with four treatment levels. The first factor was designed for different AMF species (10 g/pots): control (M0), Acaulospora delicata (M1), Septoglomus constrictum (M2), and Claroideoglomus etunicatum (M3) while the second factor was designed for different concentration of liquid organic fertilizer (mL/pots): control (P0), 150 mL/pots (P1), 200 mL/pots (P2), and 250 mL/pots (P3). Based on ANOVA results, the independent application of AMF species and liquid organic fertilizers gave significant results in regards to the experimental variables such as plant height, number of leaves, leaf area, and stem diameter. The best combination of treatment was observed in the treatment using Septoglomus constrictum with the concentration of liquid organic fertilizer of 250 mL (M2P3) to yield the highest growth performance of soybean plants on ultisols.

Serratia marcescens is a species that belongs to the family of Yersiniaceae. This family comprises taxa representing opportunistic human- and phytopathogens but also plant growth-promoting rhizobacteria (PGPR). This study describes a novel Gram-negative strain (LVF3R) of the species Serratia marcescens. The strain was characterized genomically, morphologically, and physiologically. In addition, the potential of the isolate to act as a host strain to assess the diversity of Serratia associated phages in environmental samples was explored. Average nucleotide identity analysis revealed that LVF3R belongs to the species Serratia marcescens. In silico analysis and ProphageSeq data resulted in the identification of one prophage, which is capable of viral particle formation. Electron microscopy showed cells of a rod-shaped, flagellated morphotype. The cells revealed a length and width of 1–1.6 μm and 0.8 μm, respectively. LVF3R showed optimal growth at 30 C and in the presence of up to 2% (w/v) NaCl. It exhibited resistances to ampicillin, erythromycin, oxacillin, oxytetracycline, rifampicin, tetracycline, and vancomycin. Genome data indicate that strain S. marcescens LVF3R is a potential PGPR strain. It harbors genes coding for indole acetic acid (IAA) biosynthesis, siderophore production, plant polymer degradation enzymes, acetoin synthesis, flagellar proteins, type IV secretion system, chemotaxis, phosphorous solubilization, and biofilm formation.

The aim of this study was to evaluate the effects of plant growth-promoting rhizobacteria effects on anatomical characteristics and nutritional value of Brachiaria (Syn. Urochloa) brizantha cv. BRS Piatã. The experimental design applied was completely randomized design  with three treatments: (1) non-inoculated unfertilized-control plants (C-), (2) non-inoculated fertilized-control plants (C+) and (3) B. brizantha inoculated with Pseudomonas fluorescens (BRM-32111) and Burkholderia pyrrocinia (BRM-32113). The following parameters were evaluated at 35 days after seedling emergence: biomass production, plant height, net photosynthesis (A), water-use efficiency (WUE), chlorophyll (SPAD), anatomical and nutritional. The rhizobacteria modified the anatomy of the leaf, culm and roots of B. brizantha. They also increased the chlorophyll content, A, WUE, total soluble carbohydrates, starch and crude protein contents, N, P, Mg and Fe concentrations, plant height, root area and biomass production. Therefore, we conclude that co-inoculation with P. fluorescens (BRM-32111) and B. pyrrocinia (BRM-32113) modified the anatomy and biochemistry of B. brizantha, promoting growth and nutrient accumulation. Therefore, these findings set up the basis for additional exploratory studies, using these rhizobacteria as biotechnological innovation with potential of use as biofertilizer in B. brizantha, aiming higher productivity and nutritive value in a more eco-friendly and sustainable pasture production system.

This study aimed to find an effective combination of mycorrhiza, PGPR (Plant Growth Promoting Rhizobacteria), and inorganic fertilizers. Whereas the specific purpose was observed in effective mycorrhiza to increased chlorophyll content. This study used a completely randomized design (CRD) with three factors: the 1st factor is mycorrhiza application, the 2nd factor is PGPR and the 3rd factor is the application of nitrogen and phosphorus fertilizers. The data were analyzed with Analysis of Variance to determine the effect of the treatment being tried. Continued with the Least Significance Different test at a 95 % confidence level. The results indicated that the most effective application in increasing total chlorophyll content was (i) the ‟Commercial Mycorrhiza” without being combined with PGPR and fertilizer (TP.TR.MP:80 g mL–1). (ii) ‟Brawijaya Mycorrhiza” is combined with PGPR without fertilizer (TP.R.MB: 83 g mL–1). (iii) ‟Unida Mycorrhiza” without combined with PGPR and without fertilizer (TP.TR.MU: 80 g mL–1).

Penelitian ini dilaksanakan untuk mempelajari pengaruh berbagai konsentrasi BAP dan PGPR terhadap pertumbuhan dan hasil edamame. Percobaan dilaksanakan di Desa Cisero, Kecamatan Cisurupan, Kabupaten Garut, mulai bulan Juni sampai Agustus 2018, pada ketinggian 1.190 meter diatas permukaan laut (mdpl). Penelitan ini menggunakan Rancangan Acak Kelompok (RAK) dengan pola faktorial 4 x 4 dan dua ulangan. Faktor pertama adalah Konsentrasi BAP (0, 15, 20 dan 25 ppm). Faktor kedua adalah Konsentrasi PGPR (0, 50, 100 dan 150 ml/liter). Hasil penelitian menunjukkan bahwa tidak ada interaksi antara konsentrasi BAP dan PGPR terhadap pertumbuhan dan hasil edamame. Konsentrasi BAP 20 dan 25 ppm memberikan pengaruh mandiri terhadap tinggi tanaman, jumlah daun, luas daun, bobot kering per tanaman, jumlah bintil akar, jumlah polong per tanaman, bobot polong per tanaman dan hasil polong per plot. Konsentrasi PGPR 100 dan 150 ml/liter memberikan pengaruh mandiri terhadap tinggi tanaman, jumlah daun, bobot kering per tanaman, jumlah bintil akar, jumlah polong per tanaman, bobot polong per tanaman dan hasil polong per plot.
