Abstract
The effects of S-23142{N-(4-chloro-2-fluoro-5-propargyloxyphenyl)-3, 4, 5, 6-tetrahydrophtalimide}, on protoporphyrin IX(PPIX) biosynthesis in Spinacia oleracea L, leaf in vivo and in vitro condition were investigated by reversed-phase HPLC with fluorescence detector. The stroma and the membrane fraction of spinach chloroplast were isolated by osmotic regulation. The conversion of
In vitro 조건에서 protoporphyrin IX(PPIX) 생합성에 미치는 제초제 S-23142와 acifluorfen의 영향을 알아보고자 시금치잎에서 엽록체내의 stroma와 membrane을 분리, 분획하고 형 광검출기가 장착된 역상HPLC를 이용하여 생합성된 PPIX 함량용 분석한 결과는 다음과 같다. 1. PPIX의 생합성이 이루어지는 부위는 엽록체 내의 stroma분획이었고 이는 모두 ALA(
