拟南芥SGR2基因参与叶绿素降解和衰老过程
Arabidopsis thaliana SGR2 Genes Involved in Degradation and Senescence of Chlorophyll
摘要
Abstract
[Objective]To study Arabidopsis thaliana SGR2 genes involved in degradation and senescence of chlorophyll.[Method]T-DNA inser-tion mutants for SGR2 gene were got.The experiments of chlorophyll fluorescence analysis,determination of the content of chlorophyll and soluble sugar,qRT-PCR test and some other bioinformatics analysis were conducted.[Result]The chlorophyll content of the mutant leaves was less than the case in the wild-type.The soluble sugar content of the mutant leaves was more than the case in the wild-type.Expression of RBCS and CAB were down regulated.While,a transparently prolonged flowering period was observed in mutant,as compared with colo-0.[Conclusion]The results demonstrate that SGR2 gene is involved degradation and senescence of chlorophyll in A.thaliana.关键词
