cDNA clones encoding a novel proline-rich protein (NaPRP4) have been isolated from a Nicotiana alata stylar cDNA library. The N-terminal part of the derived protein is highly rich in proline (32.2?0) and contains several repeats such as Lys-Pro-Pro (7 times) and Pro-Thr-Lys-Pro-Pro-Thr-Tyr-Ser-Pro-S

✦ Synopsis
A clone containing a gene coding for a novel glycine-rich protein has been identified in an Arabidopsis thaliana genomic library. The gene codes for a 339 amino acid protein and is interrupted by a 686 bp intervening sequence. The gene is present in one copy only. Transcripts accumulate mainly in hypocotyls and stems and the highest level is observed in rosettes before the start of stem elongation. The protein contains 71% of glycine residues and is highly hydrophobic.

We sequenced the nucleotides around the rpl2 gene, encoding the ribosomal protein L2, in pea (Pisum sativum cv. Alaska) chloroplasts and analyzed the expression of the rpl2 gene. During deetiolation, accumulation of the rpl2 transcript did not require de novo protein synthesis on chloroplastic ribos
