AB  - A cDNA clone encoding a thiol-protease (TPE4A) was isolated from senescent ovaries of pea (Pisum sativum) by reverse transcriptase-polymerase chain reaction. The deduced amino acid sequence of TPE4A has the conserved catalytic amino acids of papain. It is very similar to VSCYSPROA, a thiol-protease induced during seed germination in common vetch. TPE4A mRNA levels increase during the senescence of unpollinated pea ovaries and are totally suppressed by treatment with gibberellic acid. In situ hybridization indicated thatTPE4A mRNA distribution in senescent pea ovaries is different from that of previously reported thiol-proteases induced during senescence, suggesting the involvement of different proteases in the mobilization of proteins from senescent pea ovaries.TPE4A is also induced during the germination of pea seeds, indicating that a single protease gene can be induced during two different physiological processes, senescence and germination, both of which require protein mobilization.
