The Primary Transcriptome of Barley Chloroplasts: Numerous Noncoding RNAs and the Dominating Role of the Plastid-Encoded RNA Polymerase[C][W][OA]

摘要

A novel differential RNA-seq approach was used to obtain a genome-wide map of transcription start sites in the chloroplast genome of barley (Hordeum vulgare). Noncoding RNAs undergo extensive synthesis in plastids, and promoters used by different types of RNA polymerases in green and white ribosome-free plastids of the barley mutant line albostrians were identified.
