Floral tissue of Petunia hybrida (V30) expresses only one member of the chalcone synthase multigene family
TL;DR: Twenty independent, petal-specific chalcone synthase (CHS) cDNA clones have been isolated from Petunia hybrida variety Violet 30 and hybridization and sequence analysis indicates the presence of only one transcriptionally active CHS gene in petals.

Protein H encoded by plasmid Clo DF13 involved in lysis of the bacterial host. I. Localisation of the gene and identification and subcellular localisation of the gene H product.
TL;DR: Although gene H is located close to the region known to be involved in Clo DF13 replication, its gene product, protein H, is not essential for the plasmid DNA replication process and the possibility of the existence of a comparable protein encoded by the related plasmids Col E1 will be discussed.

Maintenance of multicopy plasmid Clo DF13 in E. coli cells: evidence for site-specific recombination at parB
TL;DR: The genetic data indicate that transcription from the gene L-containing operon into parB is required, and it is concluded that the efficient maintenance of Clo DF13 cop derivatives containingParB is provided by resolution of mutimeric molecules.

TL;DR: White flowers of the Petunia hybrida line W43 accumulate glucosides of 4-coumaric acid and caffeic Acid and are able to synthesize anthocyanins from exogeneously supplied naringenin, suggesting that W43 is blocked in a biosynthetic step preceding the formation of naredenin.

Molecular structure and function of the bacteriocin gene and bacteriocin protein of plasmid Clo DF13
TL;DR: The sequence data obtained during this study enabled us to present the nucleotide sequence of the entire cloacin operon, and the structure of this operon and the regulation of expression of the genes, located within thisoperon, is discussed.
