Analysis of Rfo-mediated Network in Regulating Fertility Restorer in Brassica oleracea

Ogura cytoplasmic male sterility (CMS) lines play important roles in heterosis utilization. However, excellent genes such as disease-resistant genes from Ogura CMS hybrids are difficult to use for germplasm innovation, especially in cabbage and broccoli. Till now, the Rfo-mediated network in regulating fertility restorer remains largely unknown. In this study, we aim at providing intriguing insights for the fertility recovery mechanism regulated by Rfo in broccoli and give useful clues to identify the crucial genes for breeders to recovery the Ogura CMS hybrids in Brassica oleracea.
