Phytochrome-induced appearance of mRNA activity for the apoprotein of the light-harvesting chlorophyll a/b protein of barley (Hordeum vulgare).

摘要: Illumination of dark-grown barley plants induces a massive insertion the light-harvesting chlorophyll u/b protein into developing thylakoid membrane. Light specifically appearance mRNA activity for apoprotein this chlorophyll-binding [Apel, K. and Kloppstech, (1978) Eur. J. Biochem. 85, 581–588]. This change in can also be induced by 15-s red light pulse followed 4 h darkness. The effect is reversed subsequent far-red treatment. It concluded that controlled phytochrome. In continuous white a/b appears within membrane after lag period 4–5 h. could partially eliminated given prior to onset illumination. possible role phyto- chrome-induced as rate-limiting step greening process discussed. The not detected among plastid proteins which had been treated with alone. assembly takes place only under illumination allows synthesis. Thus, synthesis ultimate depends on cooperation two distinct reactions.
