PURPOSE: A transgenic plant which is prepared by transforming with a bacterial wilt resistant gene is provided to grow a variety with bacterial wilt resistance and to remarkably improve productivity of plants, especially solanaceae plants. CONSTITUTION: A method for improving bacterial wilt resistance in a plant comprises a step of increasing intracellular level of a polypeptide with an amino acid sequence of sequence number 2. The method also comprises a step of overexpressing the polypeptide. A gene encoding the polypeptide has a base sequence of sequence number 1. A method for producing a plant with resistance to bacterial wilt comprises a step of transforming a recombinant expression vector containing a gene encoding the polypeptide into a plant.본 발명은 풋마름병 저항성 폴리펩티드의 세포 내 수준을 증가시켜 식물의 풋마름병 저항성을 향상시키는 방법에 관한 것으로, 본 발명에 따라 풋마름병 병원균에 대한 저항성 유전자로 형질전환된 식물체는 풋마름병 저항성 품종으로 육성 가능하다.
