A pentatricopeptide repeat protein restores fertility in Moricandia arvensis based cytoplasmic male sterility system in Brassica juncea. (PubMed, Mol Genet Genomics) - "Based on segregation of tightly linked flanking markers, namely, the earlier reported BjESSR06 and a newly identified SRB17 marker, the Rfm gene was assigned to Scaffold-547...Further, we designed a gene-based, co-dominant marker perfectly co-segregating with fertility restorer trait through collinearity analysis of the genomic region spanning PPR-640 and the B. juncea genome. The Rfm gene and the marker reported here are critical for utilising this CMS system in hybrid breeding and to clone and study evolution of restorer genes in other Brassicaceae members."
