Transcriptional Analyzing of Cs-ppcGenes and Their Response to Light Intensity in Cucumber Leaves

doi:10.7668/hbnxb.2011.05.005

Abstract

Abstract: To study the transcription level of ppc genes in organizations of cucumber,and influences of light intensity on them in leaves,we used fluorescence quantitative PCR to detect the transcription level three cucumber ppc genes.It showed that the transcription level of Cs-ppc1 and Cs-ppc3 in many tissues were all high,while its level of Cs-ppc2 was very high in flowers and low in other tissues.By contrast,the effect of light intensity on Cs-ppc1 transcription was more obvious than the other ppc genes.Cs-ppc2′s high transcription level in flowers suggest its function in floral development,while Cs-ppc1 may play an important role in the adaption to different light intensity.

Key words: Cucumber, Phosphoenolpyruvate carboxylase, Gs-ppc genes, Light intensity, Transcription analysis
