Study of the role of the FLV/DOT4 protein in post-transcriptional regulation of chloroplast gene expression. DOT4 is a pentatricopeptide repeat protein targeted to the chloroplast which regulates the editing of the rpoC1 transcript Overall design: The editing level of rpoC1 varies from one tissue to the other and because the main macroscopic phenotype of the flv/dot4 mutant are white leaf margins. We compared the leaf border to the leaf center of wild-type Col0 plants but also the leaf borders of col0 and flv/dot4 knock out mutants by sequencing total RNA depleted from rRNA to get a global view of gene expression (including post-transcrional modifications) of the 3 plant genomes: nucleus, chloroplast and mitochondria. mRNA seq on wild-type Col and FLV mutants knock out.
