PURPOSE: A method for enhancing pathogen resistance in a plant using the FTR-c gene is provided to improve productivity of crops. CONSTITUTION: A method for enhancing pathogen resistance in a plant comprises a step of silencing the FTR-c(catalytic subunit of ferredoxin:thioredoxin reductase) gene in a plant. The gene is derived from Solanum lycopersicum. The gene has a base sequence of sequence number 1. A method for controlling pathogen resistance in the plant comprises a step of transforming a recombinant vector into the plant and a step of controlling the expression of the FTR-c gene. A composition for controlling pathogen resistance in the plant contains the FTR-c gene.본 발명은 FTR-c (catalytic subunit of ferredoxin:thioredoxin reductase) 유전자를 식물체에서 침묵시키는 단계를 포함하는 식물의 병원균 저항성을 증가시키는 방법, FTR-c 유전자를 포함하는 재조합 벡터를 식물에 형질전환시켜 FTR-c 유전자의 발현을 조절하는 단계를 포함하는 식물의 병원균 저항성을 조절하는 방법 및 병원균 저항성을 유발시키는 FTR-c (catalytic subunit of ferredoxin:thioredoxin reductase) 유전자를 포함하는 식물의 병원균 저항성 조절용 조성물에 관한 것이다.
