Abstract

A partial cDNA, isolated from an early developing pea (Pisum sativum L.) embryo library, was found to encode a plant homologue of the regulatory subunit (PR65) of protein phosphatase 2A (PP2A). Comparison of the deduced amino acid sequence with a human PR65 sequence showed that the regulatory subunit of PP2A has been highly conserved during evolution. Southern analysis demonstrated that in pea and rape the catalytic and regulatory subunits of PP2A are encoded by multigene families. The levels of the transcripts encoding each subunit are developmentally regulated during pea embryogenesis and expression of the regulatory subunit is not solely restricted to the embryo.
