Full description

Restorer-of-fertility (Rf) genes have practical applications in hybrid seed production as a means to control self-pollination. They encode pentatricopeptide repeat (PPR) proteins that are targeted to mitochondria where they specifically bind to transcripts that induce cytoplasmic male sterility and repress their expression. We have identified a unique domain, RfCTD (Restorer-of-fertility C-terminal domain), which discriminates Restorer-of-fertility-like (RFL) proteins from hundreds of PPR proteins encoded in plant genomes. Using the sequence of this domain from hundreds of plant species, we have constructed a sequence profile that can quickly and accurately identify RfCTD sequences in plant genomes or transcriptomes. This data set contains PPR genes identified in 213 plant genomes (as summarised in accompanying table).
