Tobamovirus resistance gene Tm-1

摘要

PPROBLEM TO BE SOLVED: To provide a protein having tobamovirus ToMV-resistant gene Tm-1-like activity and a polynucleotide encoding the protein. PSOLUTION: The present invention provides a polypeptide composed of a specific amino acid and a polynucleotide composed of a specific base sequence, each having Tm-1-like activity. The present invention provides an assay system by building ToMV RNA replication system by using a cell extract derived from tomato and using the RNA replication system. The present invention provides, further, a method for screening a plant body having resistance to ToMV, a kit for screening the plant body and a method for preparing a plant body in which the polynucleotide is introduced and a kit for preparing the plant body.
