The nucleotide sequence of the cDNA clone pSTV34 is reported. It codes for the 68 COOH-terminal amino acids of the protein coding for the small subunit of the ribulose bisphosphate carboxylase and has a 3′ non-translated region 195 base pairs long. In the coding region this clone is 72% homologous with the corresponding cDNA clone from Pisum sativum.
