The purpose of this research is to determine the role that post-transcriptional processes play in the regulation of phytochrome (phy) steady-state messenger RNA (mRNA) levels. The control of etiolated phytochrome (phyA) and chlorophyll a/b binding protein (cab) gene transcription and steady-state mRNA levels are known to be regulated by the phyA signal transduction pathway. I performed a number of control experiments that indicate the degradation products detected in northern analysis of phyA mRNA were produced in vivo and were not an artifact of RNA isolation techniques. I have also shown that infrared (IR) irradiation has no appreciable effect on ...
