Quantitative Change in rbcL mRNA of Maize by Phytohormones

Abstract

|
In order to investigate the effects of plant hormones on the quantitative changes in mRNA of maize (Zea mays L.) rbcL, we used GA_3, IAA, ABA and BAP. GA_3 at the concentration of 10^-4 M resulted in decrease in rbcL gene transcript to 62%. IAA decreased the amount of rbcL transcript to about 70% at all the hormone concentrations tested. ABA did not cause a noticeable change in the amount of rbcL transcript, but BAP increased the amount of rbcL transcript to 153% at 10^-8 M and 123% at 10^-5 M, respectively. Thus, it appears that BAP is related to the increase in the amount of rbcL transcript by light.
