Rhizosphere engineering with beneficial plant growth promoting bacteria offers great promise for sustainable crop yield. Potato is an important food commodity that needs large inputs of nitrogen and phosphorus fertilizers. To overcome high fertilizer demand (especially nitrogen), five bacteria, i.e., Azospirillum sp. TN10, Agrobacterium sp. TN14, Pseudomonas sp. TN36, Enterobacter sp. TN38 and ...

BACKGROUND Soybean red crown rot is a major soil-borne disease all over the world, which severely affects soybean production. Efficient and sustainable methods are strongly desired to control the soil-borne diseases. PRINCIPAL FINDINGS We firstly investigated the disease incidence and index of soybean red crown rot under different phosphorus (P) additions in field and found that the natural i...

Rhizobium fredii USDA257 fails to nodulate the improved soybean [Glycine max (L.)Merr.] cultivar McCall in plastic growth pouches. Mutant 257DH4, which was derived from USDA257 by transposon mutagenesis, forms nitrogen fixing nodules under these conditions. If USDA257 is present in inocula containing the mutant, most infections are arrested prior to organization of the nodule meristem, and nodu...

Because of their beneficial impact on plants, the highly diverse mycorrhizal fungi grouped in the order Sebacinales lay claim to high ecological and agricultural significance. Here, we describe for the first time associations of Sebacinoid members with bacteria. Using quantitative PCR, denaturating gradient gel electrophoresis and fluorescence in situ hybridization, we detected an intimate asso...

Background: Phytophthora blight (PB), caused by drechsleri f. sp. cajani, is soil borne disease of pigeonpea (Cajanus cajan L.). The use plant growth promoting rhizobacteria (PGPR) in agriculture leads to alternative management crop a sustainable ecofriendly way. Methods: In vitro and vivo experimentation was conducted at fields Punjab Agricultural University, Ludhiana during kharif season 2017...

Rhizobium spp. are found in soil. They are both free-living and found symbiotically associated with the nodules of leguminous plants. Traditionally, studies have focused on the association of these organisms with plants in nitrogen-fixing nodules, since this is regarded as the most important role of these bacteria in the environment. Rhizobium sp. are known to possess several replicons. Some, l...

Bacteria harbored in/on the hyphae of the dark septate endophyte, Veronaeopsis simplex Y34, were identified as a single Rhizobium species by molecular analyses of bacterial 16S rRNA genes, and were successfully isolated from the endophyte. The Rhizobium-cured fungus was prepared thoroughly by an antibiotic treatment, thereby allowing an examination of their effects on organic substrate utilizat...

In order to study the effect of zeolite and biologic fertilizers application under different irrigation regime on yield and quantitative traits in sugar beet, a research project was conducted according split-split plot experiment based on randomized complete block design with four replicates. The main factor included irrigation regime at two levels (Normal and stress), sub factor included zeoli...

in this study, the ability of 32 rhizobium strains (26 strain of sinorhizobium meliloti (sm)), 4 strains of rhizobium leguminosarum biovar phaseoli (rlp) and 2 salt tolerance strains of rhizobium leguminosarum  biovar viciae (rlv) for use of acc as individual nitrogen source in rmm media was evaluated. based on the results, 25 strains were found positive for acc-deaminse, and strains according ...
