초록

4-HPPD저해 제초제에 의한 주요 벼품종의 약해반응과 약제반응에 관여하는 유전자(HIS1) 특성을 구명하기 위해 본시험을 수행하였다. Benzobicyclon 액상수화제 처리에 Japonica 품종인 상주벼에는 백화증상의 약해증상이 발생하지 않았으며, Japonica 품종임에도 불구하고 삼백벼에서는 기준량에서는 2-3, 배량에서는 3-4의 백화증상의 약해가 발생하였으며, 산들진미, 금영 품종에서는 3-4 및 4-5의 약해증상을 보였다. 또한 Indica 품종인 IR-8 품종에서는 기준량에서 3~5, 배량에서는 4~6의 가증 심한 약해증상을 보였다. 4-HPPD저해 제초제애 대해서 약제반응에 관여하는 HIS1 유전자 보유여부를 확인하기 위해 일반계 품종인 상주벼와, 삼백벼, 산들진미, 금영과 통일형 품종인 IR-8품종으로부터 저항성 표적유전자와 동일 HIS1 유전자를 분리하였다. 각 품종별 HIS1유전자를 PCR등을 통해 염기서열을 확인한 결과 HIS1 유전자는 생태형에 상관없이 시험한 5품종 모두에서 HIS1유전자를 보유하고 있는 것으로 확인되어, 본 유전자로 HPPD 약해 발생 유무를 검증할 수 없음이 확인되었다.

This study was conducted to determine phytotoxicity of domestic rice varieties and characteristic of sensitive gene involved in herbicide reaction of 4-HPPD (4-hydroxy phenylpyruvate dioxygenase) inhibiting herbicides. The five rice varieties were grown for 2 to 3 leaf stage on seedling trays and then transplanted into plastic pot: 4-Japonica type (Sangjubyeo, Sambaekbyeo, Sanduljinmi and Kumyoung) varieties and 1-Indica type variety (IR8). We trialled standard (14 g a.i. $10a^{-1}$) and double fold (28 g a.i. $10a^{-1}$) dose of benzobicyclon treatment at 10 days after transplanting in order to investigate phytoxicity. The Japonica-type Sangjubyeo showed no rice injury but Indica-type IR8 show 4-5 (standard) and 5-6 (double fold) phytoxicity levels. In spite of Japonica-type, Sanduljinmi and kumyoung showed 3-4 and 4-5 levels. Target resistant gene, Hydroxyphenylpyruvate dioxygenase inhibitor sensitive gene No.1 (HIS1) have been isolated from five domestic rice cultivars (Sangjubyeo, Sambaekbyeo, Sanduljinmi, Kumyoung and IR8). Results of the sequence through PCR, all five tested rice cultivars had HIS1 gene regardless to rice cultivars. And the difference between rice varieties from sequence of HIS1 were identified some variation in genes.
