Abstract:
A vector comprising hrp(hypersensitive response and pathogenicity) gene encoding harpin protein, derived from Erwinia pyrifoliae, and a transgenic Agrobacterium tumefaciens and a pathogenic resistant transgenic plant by using the same vector are provided to activate the pathogenic resistant mechanisms of the plant itself without inducing hypersensitive response and replace toxic agricultural chemicals. The vector pMJC-GB-hrpEp comprises hrpEP gene derived from Erwinia pyrifoliae wild type #3 KCCM 10283. The transgenic Agrobacterium tumefaciens is produced by transforming Agrobacterium tumefaciens by the vector pMJC-GB-hrpEp. The pathogenic resistant transgenic plant is produced by transforming a plant by the vector pMJC-GB-hrpEp or the transgenic Agrobacterium tumefaciens, wherein the plant is tobacco or rice.
Abstract:
PURPOSE: A manless spore collection device for aerial infectious pathogenic microorganism is provided to prevent aerial infections by collecting pathogen air spore in a real-time basis and obtain an accurate monitoring data. CONSTITUTION: A manless spore collection device for aerial infectious pathogenic microorganism comprises a base(110), a container cover sliding shuttle(130), and a lifting shuttle(120). The container cover sliding shuttle is mounted on a case(101). If a cover of a culture media which is descended into the case is hung and put on, the container cover sliding shuttle can slide the cover in the right or left side. The base elevation shuttle is mounted on the case. The base elevation shuttle can vertically elevate the base by penetrating through the container cover sliding shuttle.
