Fig. 7From: Comparative genomic analysis of the compound Brassica napus Rf locusPhylogeny of Brassica and Arabidopsis PPR proteins. A maximum likelihood tree was generated by the PhyML resource using as input the sequences of known dicot restorer proteins and related orthologs, the predicted protein sequences of A. thaliana subgroup 1 RFL proteins, A. lyrata proteins predicted from our analysis of the targeted region enriched in subgroup 1 RFL proteins [22], and the B. napus, B. rapa and B. oleracea RFL proteins of the Brassica Rf-region. Numbers in red flanking each node indicate bootstrap valuesBack to article page
