摘要
传统的理论认为:从厌氧光合细菌到裸子植物能够通过非光依赖途径合成叶绿素,而被子植物只能通过光依赖途径合成叶绿素。然而,被子植物中却存在着许多与此相矛盾的事实,它们的一些器官在黑暗条件下能转绿。本研究通过Arnon Lichtenthaler法和PAGE法,对其绿色胚的叶绿素、酯酶同工酶和可溶性蛋白进行了比较分析,提出以下3种可能:在被子植物中,可能存在与LIPOR相关的基因,可能存在能合成LIPOR的共生菌物,可能存在着可替代可见光的生物活性物质。
Up to now, the traditional theory holds that the LIPOR pathway can syn thesize chlorophyll from anoxygenic photosynthetic bacteria to gymnosperms, and the POR pathway is the only mechanism used for chlorophyll synthesis in angiospe rms. However, a lot of fact contraries to the theory exist in angiosperms, and s ome organs of them can turn green in dark. This is a enigma in plants. Chlorophy ll, EST and soluble protein of the angiosperms' greening embryos were studied by methods of ArnonLichtenthaler and PAGE. Three opinions are posed in angiosper ms that: 1) There can be genes interrelated LIPOR; 2) There can be symbiosis bac teria that synthesize LIPOR; 3) There can be biological activity substance which can substitute visible light.
