It is shown that the monovinyl and divinyl protochlorophyllide biosynthetic patterns of etiolated maize (Zea mays L.), and cucumber (Cucumis sativus L.) seedlings and of their isolated etiochloroplasts can be modulated by light and darkness as was shown for green photoperiodically grown plants (E. E. Carey, C. A. Rebeiz 1985 Plant Physiol. 79: 1-6). In etiolated corn and cucumber seedlings and isolated etiochloroplasts poised in the divinyl protochlorophyllide biosynthetic mode by a 2 hour light pretreatment, darkness induced predominantly the biosynthesis of monovinyl protochlorophyllide in maize and of divinyl protochlorophyllide in cucumber. When etiolated seedlings and their isolated etiochloroplasts were poised in the monovinyl protochlorophyllide biosynthetic mode by a prolonged dark-pretreatment, light induced mainly the biosynthesis of divinyl protochlorophyllide in both maize and cucumber.
研究表明,光和暗可以调节黄化玉米(Zea mays L.)、黄瓜(Cucumis sativus L.)幼苗及其分离的叶绿体中叶绿素原生物合成的单乙烯基和二乙烯基模式,正如在绿色光周期生长的植物中所显示的那样(E. E. Carey,C. A. Rebeiz 1985 年,植物生理学 79: 1-6)。在黄化玉米和黄瓜幼苗及分离的叶绿体中,通过 2 小时的光预处理处于二乙烯基叶绿素原生物合成模式下,黑暗主要诱导玉米中单乙烯基叶绿素原的生物合成和黄瓜中二乙烯基叶绿素原的生物合成。当黄化幼苗及其分离的叶绿体在单乙烯基叶绿素原生物合成模式下通过长时间的暗预处理时,光主要诱导玉米和黄瓜中二乙烯基叶绿素原的生物合成。
