Cowpea (Vigna unguiculata) and mung bean (Vigna radiata) are important legume crops yet their rhizobia have not been well characterized. In the present study, 62 rhizobial strains isolated from the root nodules of these plants grown in the subtropical region of China were analyzed via a polyphasic approach. The results showed that 90% of the analyzed strains belonged to or were related to Brady...

Background: Cropping system approach has gained importance in agriculture and relative enterprises. In agriculture, management practices are usually formulated for individual crops. However, farmers cultivating different crops seasons based on their adaptability to a particular season, domestic needs profitability, therefore production technologies should be developed keeping view of grown sequ...

twenty six rhizobium strains were isolated from root nodules of sesbania sesban (l.) merr. collected from different regions of andhra pradesh. all the 26 rhizobium strains produced indole acetic acid (iaa), but maximum amount was produced by only five strains in yeast extract mannitol  (yem) medium supplemented with l-tryptophan. the strains were found to elaborate maximum iaa when fed with 2.5...

The novel lipochitin oligosaccharide (LCOs) structures produced by Rhizobium etli KIM5s were characterized using a nanoHPLC reverse-phase system coupled to an ion-trap mass spectrometer. This technique was shown to be more sensitive for structural elucidation of LCOs than previously used mass spectrometric methods. The structures of the LCOs of R. etli KIM5s, the majority containing six monosac...

A field experiment was conducted during Rabi season 2021-22 at the experimental of Crop Research Farm, Department Agronomy, Naini Agricultural Institute, Sam Higginbottom University Agriculture, Technology And Sciences, Prayagraj, Uttar Pradesh. India which is located 250 30’ 42’’N latitude, 810 60’ 56” E longitude, and a height 98 meters above sea level. The Experiment laid out in Randomized B...

Many animal-pathogenic bacteria can use heme compounds as iron sources. Like these microorganisms, rhizobium strains interact with host organisms where heme compounds are available. Results presented in this paper indicate that the use of hemoglobin as an iron source is not restricted to animal-pathogenic microorganisms. We also demonstrate that heme, hemoglobin, and leghemoglobin can act as ir...

Rhizobium strains nodulating green gram [Vigna radiata (L.) Wilczek] were found to produce bacteriocin on modified Bergersen's medium and inhibited the growth of homologous Rhizobium strains. Four bacteriocin producing and four bacteriocin non-producing strains were compared for their effect on nodulation, in planta nitrogenase activity and plant dry weight of green gram. The bacteriocin produc...
