“…Interestingly, major Rf genes for other CMS systems in rice, such as Rf1 for BT-type CMS, Rf4 for WA-type CMS, Rf-D1(t) for Dian1-type CMS, Rf5 for HL-type CMS, and qRf-10-2 for DA-type CMS, were detected on the same region of chromosome 10 [17, 19, 25, 45–47] and were closely linked to form a gene cluster. Cloning of the Rf genes and sequence analysis reported by Tang et al [24] and Hu et al [25] revealed that the fertility restorer locus Rf1a was identical to the locus Rf5 but different from the locus Rf4 .…”

Hybrid rice breeding using cytoplasmic male sterility/fertility restoration (CMS/Rf) systems plays an important role in ensuring global food security. Two backcross inbred line (BIL) populations derived from either Xieqingzao B (XB)//XB/Dongxiang wild rice (DWR) (XXD) or XB//DWR/XB (XDX) were used to detect quantitative trait loci (QTLs) for fertility restoration of Dwarf wild abortive- (DA-), Indonesia Paddy- (ID-), and DWR-type CMS in rice. Lines with ID- and DA-type CMS were testcrossed with both the XXD- and XDX-BILs, while the line with DWR-type CMS was testcrossed with the XDX-BILs only. A total of 16 QTLs for fertility restoration of CMS systems were identified, including three for DWR-type CMS, six for DA-type CMS, and seven for ID-type CMS. All of the additive alleles in the QTLs were derived from Oryza rufipogon. Eleven QTLs were clustered in five chromosomal regions, indicating that common Rf loci restored different CMS systems, and the favorable O. rufipogon alleles could be used to develop restorer lines for various CMS types by marker-assisted selection.

“…Th e cloned Rf genes of radish (Raphanus sativus L.), rice (Oryza sativa L.), and petunia [Petunia ×atkinsiana (Sweet) D. Don ex W. H. Baxter [= P. axillaris × P. integrifolia] (syn. Petunia hybrida L.)] are present in clusters of PPR-encoding genes with one functional gene and multiple pseudogenes suggesting recent gene duplication (Akagi et al, 2004;Bentolila et al, 2002;Brown et al, 2003;Desloire et al, 2003;Komori et al, 2003). Th ree of the restorer genes in sorghum [Sorghum bicolor (L.) Moench] reside in PPR clusters that share similarity to rice OsRf1 (Klein et al, 2005;Jordan et al, 2011).…”

Rf8-Mediated T-urf13Transcript Accumulation Coincides with a Pentatricopeptide Repeat Cluster on Maize Chromosome 2L

Cytoplasmic male sterility (CMS) is a maternally inherited inability to produce functional pollen. In Texas (T)-cytoplasm maize (Zea mays L.), CMS results from the action of the URF13 mitochondrial pore-forming protein encoded by the unique T-urf13 mitochondrial gene. Full or partial restoration of fertility to T-cytoplasm maize is mediated by the Rf2a nuclear gene in combination with one of three other genes: Rf1, Rf8, or Rf*. Rf2a encodes a mitochondrial aldehyde dehydrogenase whereas Rf1, Rf8, and Rf* are associated with the accumulation of distinctive T-urf13 mitochondrial transcripts. Rf8-associated RNA processing activity was mapped to a 4.55-Mbp region on chromosome 2L that contains 10 pentatricopeptide repeat (PPR) encoding genes in the B73 5b.60 genome assembly. Genetic linkage analysis also indicated that Rf* is positioned within this PPR cluster as well as Rf3, which restores USDA (S)-cytoplasm maize. Partially male-fertile plants segregated for the presence or absence of the Rf8-associated T-urf13 1.42-and 0.42-kbp transcripts, indicating that the RNA processing event associated with these transcripts is not necessary for anther exsertion. In addition, a statistically signifi cant delay in fl owering was observed between partially male-fertile and mostly male-fertile plants. Taken together, these new results indicate that Rf8-mediated male fertility is under the control of more than one nuclear locus.
