Essential nucleoid proteins in early chloroplast development

摘要: The plastid transcription machinery can be biochemically purified at different organisational levels as soluble RNA polymerase, transcriptionally active chromosome, or nucleoid. Recent proteomic studies have uncovered several novel proteins in these structures and functional genomic indicated that a lack of many results chlorotic phenotypes varying degree. most severe cases exhibit complete albino phenotypes, which led to the conclusion were lacking had important regulatory roles gene expression chloroplast development. In this opinion article, we propose an alternative model structural establishment transcriptional subdomain within nucleoid represents early developmental bottleneck leads abortion proper biogenesis if disturbed.
