  • Cobalt reduces nitrate inhibition of nodulation in mungbean (Vigna Radiata)
    Biology and Fertility of Soils, 2000
    Co-Authors: Veena Jain, H. S. Nainawatee
    Abstract:

    A cobalt-mediated decrease in ethylene production reduced the inhibition of nodulation by nitrate in Vigna Radiata (mungbean). Nitrate increased the ethylene production in 5-day-old seedlings, while it caused a reduction in the nodulation status (nodule number and nodule weight) and nodule efficiency (acetylene reduction activity) in mungbean plants. The application of cobalt chloride inhibited nitrate-affected ethylene production and also decreased the inhibitory effect of nitrate on nodulation. The effect of cobalt was most marked on nodule number.

  • Influence of Rhizosphere Application of Syringaldehyde on Rhizobia — Mungbean (Vigna Radiata) Symbiosis
    Biochemie und Physiologie der Pflanzen, 1991
    Co-Authors: Veena Jain, Nisha Garg, H. S. Nainawatee
    Abstract:

    Summary The efficiency of mungbean (Vigna Radiata) — rhizobia symbiosis was influenced by the rhizosphere application of syringaldehyde and naringenin. Syringaldehyde caused increase in nodule number (6–26%), nodule weight (9–36%) and nitrogenase activity (16–38%). Naringenin had an inhibitory effect on various parameters of symbiosis. There was increase in the plant biomass production by syringaldehyde treatment. These results open up a possibility of enhancement of biological nitrogen fixation by rhizosphere application of nod gene regulators.

  • Vigna Radiata (L.) R. Wilczek Extract Inhibits Influenza A Virus by Targeting Viral Attachment, Penetration, Assembly, and Release.
    Frontiers in pharmacology, 2020
    Co-Authors: You-ting Chen, Hui-wen Chen
    Abstract:

    Vigna Radiata (L.) R. Wilczek (mung bean) is a Chinese functional food with antioxidant, antimicrobial and anti-inflammatory activities. However, little is known about its antiviral activity. We aimed to investigate the antiviral activity and mechanisms of action of Vigna Radiata extract (VRE) against influenza virus. HPLC was conducted to analyze the components of the VRE. The anti-influenza viral activity of VRE in Mardin-Darby canine kidney (MDCK) cells was evaluated by virus titration assays, hemagglutination assays, quantitative RT-PCR assays, cellular α-glucosidase activity assays and neuraminidase activity assays. Chromatographic profiling analysis identified two major flavonoids, vitexin and isovitexin, in the ethanol extract of Vigna Radiata. Through in vitro studies, we showed that VRE, at concentrations up to 2,000 μg/ml, exhibited no cytotoxicity in MDCK cells. VRE protected cells from influenza virus-induced cytopathic effects and significantly inhibited viral replication in a concentration-dependent manner. A detailed time-of-addition assay revealed that VRE may act on both the early and late stages of the viral life cycle. We demonstrated that 1) VRE inhibits virus entry by directly blocking the HA protein of influenza virus; 2) VRE inhibits virus entry by directly binding to cellular receptors; 3) VRE inhibits virus penetration; 4) VRE inhibits virus assembly by blocking cellular α-glucosidase activity, thus reducing HA protein trafficking to the cell surface; and 5) VRE inhibits virus release by inhibiting viral neuraminidase activity. In summary, Vigna Radiata extract potently interferes with two different subtypes of influenza viruses at multiple steps during the infectious cycle, demonstrating its broad-spectrum potential as an anti-influenza preventive and therapeutic agent. Continued development of Vigna Radiata-derived products into antiviral therapeutics is warranted.
