Identification of replication and stability functions in the complete nucleotide sequence of plasmid pUH24 from the cyanobacterium Synechococcus sp. PCC 7942.

The complete nucleotide sequence is presented for pUH24, the small plasmid of Synechococcus sp. PCC 7942. pUH24 consists of 7835bp and has a G + C content of 59%.

Tissue-specific expression directed by an Arabidopsis thaliana pre-ferredoxin promoter in transgenic tobacco plants.

We have isolated and analyzed a pre-ferredoxin gene from Arabidopsis thaliana. This gene encodes a 148 amino acid precursor protein including a chloroplast transit peptide of 52 residues. Southern analysis shows the presence of a single copy of this ferredoxin (Fd) gene in the A.

Plastocyanin of Arabidopsis thaliana; isolation and characterization of the gene and chloroplast import of the precursor protein.

A genomic clone encoding the plastocyanin precursor was isolated from an Arabidopsis thaliana lambda EMBL3 library, with the help of a heterologous hybridization probe. The nucleotide (nt) sequence encoding the 171-amino acid precursor protein and 650 bp of the 5'-flanking region were determined. S1 nuclease mapping showed the Arabidopsis coding region to be uninterrupted and the transcript to possess an untranslated leader of approx.
