Abstract

 

KHCOand NaHSO3 were sprayed on the leaves of cucumber, and HCO3-, K+, HSO3- in liquor can accelerate the expression of ribulose-1,5-bisphosphate carboxylase/oxygenase (RUBISCO)  large-subunit (rbcL) and RUBISCO small-subunit (rbcS) genes. These resultsproved that, mRNA content in the leaves of rbcL and rbcS was increased and the carboxylation activity of RUBISCO was also improved obviously, the content of RUBISCO has not increased but decreased. According to the analysis, we obtain that K,HCO3-, HSO3could affect the expression of rbcL and rbcS in a transcription way.

 

Key words: RUBISCO large-subunit (rbcL), RUBISCO small-subunit (rbcS) expression,RUBISCO.
