Data for: A unique C-terminal domain contributes to the molecular function of restorer-of-fertility proteins in plant mitochondria

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).
