摘要

水稻(Oryza sativa L.)转绿型白化突变系W_(25)在转绿过程中叶绿素、可溶性蛋白质和Rubisco含量的动态变化过程表明,白化突变体内叶绿素、可溶性蛋白质和Rubisco含量极低,随着转绿过程各组分含量迅速提高,转绿至第30d时超过野生种2177s;Rubisco初始活力与Rubisco活化酶含量呈极显著正相关。Rubisco活化酶基因表达的研究结果表明,突变体的Rubisco活化酶表达高于野生种2177s。在转绿过程中,Rubisco活化酶含量的提高要先于Rubisco和光合速率。

Abstract

Regression analysis showed that Rubisco activase content was highly correlated with initial Rubisco activity. Rubisco activase had an effect on photosynthetic rate by its regulating the initial Rubisco activity.

Key words: Mutant;RubisCO;Rubisco activase;Photosynthetic rate
