Gynodioecy, the coexistence of hermaphrodites and females (i.e. male-sterile plants) in natural plant populations, most often results from polymorphism at genetic loci involved in a particular interaction between the nuclear and cytoplasmic genetic compartments (cytonuclear epistasis): cytoplasmic male sterility (CMS). Although CMS clearly contributes to(More)
BACKGROUND Land plant genomes contain multiple members of a eukaryote-specific gene family encoding proteins with pentatricopeptide repeat (PPR) motifs. Some PPR proteins were shown to participate in post-transcriptional events involved in organellar gene expression, and this type of function is now thought to be their main biological role. Among PPR genes,(More)
In higher plants, hermaphrodites may genetically loose their male fertility through the cytoplasmic male sterility (CMS) system. In radish, a nuclear locus, denoted Rfo, has evolved that is able to counteract the effect of CMS and restore the fertility. This locus encodes three similar genes in tandem that belong to the pentatricopeptide repeat (PPR) family(More)
