  • Publication number: 20220204985
    Abstract: The present disclosure relates to a composition for promoting plant growth containing an YxaL protein and a method for mass-producing an YxaL protein. The YxaL protein may be expressed constitutively and in large amounts in a recombinant transformed cell line. When the YxaL protein is applied to seed soaking treatment, root development is improved, and the expression of plant genes involved in root growth is improved in favor of plant growth. Thus, the YxaL protein may be effectively used to promote plant growth.

  • Patent number: 7026881
    Abstract: In a wideband variable frequency voltage controlled oscillator, an LC resonance circuit determines an oscillation frequency based on an externally inputted voltage signal. A negative resistance generating circuit generates a signal having the oscillation frequency determined by the LC resonance circuit. A buffer circuit transfers the oscillation frequency generated by the negative resistance generating circuit to a load. A variable capacitor connecting circuit connects the negative resistance generating circuit and the buffer circuit to transfer the signal having the oscillation frequency from the negative resistance generating circuit to the buffer circuit.
