叶色白化水稻突变体转绿中若干生理与叶绿体发育特型的研究
Chloroplast Development and Physiological Characteristics of Green-Revertible Albino Leaf Color Mutants in Rice
摘要
Abstract
A green-revertible albino leaf color mutant rice and its wild-type parent were used as the materials to study the changes of blade about physiological characteristics and chloroplast ultrastructural during mutant leaves turning green.The results showed that as the mutant leaves turn green,the content of chlorophyll and soluble protein increased,but the activity of superoxide dismutase (SOD)decreased; after mutant leaves turn green completely,a clear Fe-SOD band appeared in SOD activity electrophoresis; at the 2-leaf age,there were many cystic vacuoles and no chloroplasts in the mesophyll cells of mutant leaves,but many chloroplasts in the wildtype parent leaves; at the 6-leaf age,the chloroplasts could be observed in the mesophyll cells of the mutant,with irregular and abnormal shape.The chloroplast in the wild-type parent could develop from proplastid directly and normally,but the chloroplast in the mutant developed through "proplastid to etioplast to chloroplast" and its development was delayed obviously.关键词
