Plastid genes are transcribed by two types of RNA polymerase in angiosperms: the bacterial
type plastid-encoded RNA polymerase (PEP) and one (RPOTp in monocots) or two (RPOTp …

Although genomes of mitochondria and plastids are very small compared to those of their
bacterial ancestors, the transcription machineries of these organelles are of surprising …

Transcription in plastids is mediated by a plastid-encoded multimeric (PEP) and a nuclear-
encoded single-subunit RNA polymerase (NEP) and a still unknown number of nuclear …

Plastids contain multiple copies of the plastid chromosome, folded together with proteins
and RNA into nucleoids. The degree to which components of the plastid gene expression …

The plastid transcription machinery can be biochemically purified at different organisational
levels as soluble RNA polymerase, transcriptionally active chromosome, or nucleoid. Recent …

Plastids (chloroplasts) possess their own genetic information and consequently, express
heritabletraits. The plastid genome (plastome) occurs at high copy numbers, with up to …

The major RNA polymerase activity in mature chloroplasts is a multisubunit, Escherichia coli-
like protein complex called PEP (for plastid-encoded RNA polymerase). Its subunit structure …

This chapter describes the components of the transcriptional apparatus in plastids (RNA
polymerases, promoters, transcription factors) and their roles in transcription. The …

Plastid transcription is crucial for plant growth and development. There exist two types of
RNA polymerases in plastids: a nuclear-encoded RNA polymerase (NEP) and plastid …

This article concerns the intriguing protein Whirly1 (Why1) that belongs to a small family of
singlestranded DNA-binding proteins and has been described to have functions in the …
