Phytochrome is known to regulate the expression of several major nuclearencoded polypeptides at the level of transcription. Both in vivo and in vitro methods are currently being used to determine the step(s) between the light activation of phytochrome and changes in gene expression.
Two different molecular species of phytochrome apoprotein in terms of amino-acid sequences, phytochrome I (PI) and phytochrome II (PII), are found in pea tissues (H. Abe et al., 1989, Plant Cell Physiol. 30, 1089-1097). The single-copy pea PI gene produces at least three distinct transcripts (mRNAs
