Abstract:
PURPOSE: A bidirectional promoter of sweet potato leaf curl infection DNA virus is provided to produce vector product in molecular biology field and molecular breeding industry. CONSTITUTION: A bidirectional promoter of sweet potato leaf curl infection DNA virus is denoted by the sequence of the sequence number 1. A method for identifying the promoter activity comprises: a step of isolating a site with promoter activity and analyzing cis-acting regulation site; a step of recombining promoter site by using gateway cloning to a plant expression vector for promoter analysis; a step of transforming the recombined promoter site to Agrobacteria tumefaciens strain GV3101; and a step of screening transformant.
Abstract:
A recombinant protein derived from small brown planthopper is provided to be specifically coupled to thread-shaped rice stripe virus, thereby forecasting precise RSV outbreak, developing a transgenic plant having RSV resistance and being applied as various tools for detecting the RSV. A recombinant protein described in SEQ ID : NO. 2 is obtained by expressing a recombinant protein in a gene clone(deposition no. KACC-95060P) described in SEQ ID : NO. 1, which is constructed by inserting a GroEL gene isolated from small brown planthopper into an expression vector, and then purifying the protein using His-taq Ni-NTA agarose column and is characterized in that it is specifically coupled to thread-shaped RSV. A method for detecting an RSV gene comprises the steps of: (a) coating a reaction container which is PolySorp treated with the GroEL recombinant protein derived from the small brown planthopper or an antibody thereof with a coating solution; (b) treating the reaction solution with a detecting sample through coupling reaction with the with the RSV to immuno-capturing RSV particles; and (c) after isolating genes from the immuno-captured RSV particles, subjecting the isolated genes to RT-PCR to detect genes of the RSV.

Abstract:
The present invention relates to a method for screening a material for inducing resistance against plant diseases, the method comprising the steps of: (a) smearing a sample for inspection on the leaf of an indicator plant; (b) smearing a standard sample on the left half of the indicator plant of step (a); (c) leaving the leaf of step (b) in order to exhibit a local lesion; and calculating the number of local lesions exhibited on the leaf of step (c) in order to be substituted for a potency (CVT) inspection formula so that the antiviral functions of a tested material can be determined. The method according to the present invention indicates pass standards and indexes through plant antivirus active potency metrization so as to provide a means which is useful in developing environmentally-friendly agriculture materials by ensuring a standard method to inspect the activity of an antiviral agent against plant viruses. The method is also useful in objectively managing the quality of the environmentally-friendly agriculture materials.
