Promotion of nod Gene Inducers and Nodulation in Common Bean (Phaseolus vulgaris) Roots Inoculated with Azospirillum brasilense Cd.
نویسندگان
چکیده
Inoculation of Phaseolus vulgaris with Azospirillum brasilense Cd promoted root hair formation in seedling roots and significantly increased total and upper nodule numbers at different concentrations of Rhizobium inoculum. In experiments carried out in a hydroponic system, A. brasilense caused an increase in the secretion of nod gene-inducing flavonoids, as was observed by nod gene induction assays of root exudates fractionated by high-performance liquid chromatography. Possible mechanisms involved in the influence of A. brasilense on this symbiotic system are discussed.

Phosphorus use efficiency in common bean (Phaseolus vulgaris L.) as related to compatibility of association among arbuscular mycorrhizal fungi and rhizobia
The tripartite symbiosis of common bean (Phaseolus vulgaris L.) recombinant inbred line (RIL) 147 with rhizobia and arbuscular mycorrhizal fungi (AMF) was assessed in sand culture by comparing the effects of three AMF species on the mycorrhizal root colonization, rhizobial nodulation, plant growth and phosphorus use efficiency for symbiotic nitrogen fixation. Although Glomus intraradices well c...

Nitrogen deficit is one of the most limiting nutrients for plant production. Therefore, identifying diazotrophic indigenous inoculants to promote nitrogen fixation have a great importance in agriculture. In the current study, a number of rhizobacteria isolated from nodules of different legumes cultured in Kerman (IRAN) province. Isolates were screened for their ability to grow on N-free media. ...

A genome-wide analysis identified the set of small RNAs (sRNAs) from the agronomical important legume Phaseolus vulgaris (common bean), including novel P. vulgaris-specific microRNAs (miRNAs) potentially important for the regulation of the rhizobia-symbiotic process. Generally, novel miRNAs are difficult to identify and study because they are very lowly expressed in a tissue- or cell-specific m...
متن کاملPhaseolus vulgaris recognizes Azorhizobium caulinodans Nod factors with a variety of chemical substituents.
Phaseolus vulgaris is a promiscuous host plant that can be nodulated by many different rhizobia representing a wide spectrum of Nod factors. In this study, we introduced the Rhizobium tropici CFN299 Nod factor sulfation genes nodHPQ into Azorhizobium caulinodans. The A. caulinodans transconjugants produce Nod factors that are mostly if not all sulfated and often with an arabinosyl residue as th...
