| Title: Inheritance and molecular mapping of two fertility-restoring loci for Honglian gametophytic cytoplasmic male sterility in rice ( Oryza sativaL . ) .
| | Journal: Mol . Genet . Genomics Citation: V : 271 ( 5 ) P : 586-94 Year: 2004 Type: ARTICLE | | Literature: oryza Field: abstract Doc ID: pub15057557 Accession (PMID): 15057557 | Matching Sentences:
[ Sen. 3, subscore: 1.00 ]: Previous studies have shown that fertility restoration is controlled by a single locus located on chromosome 10 , close to the loci Rf1 and Rf4 , which respond to cms-BT and cms-WA , respectively .
[ Sen. 8, subscore: 1.00 ]: The results also demonstrated these loci are distinct from Rf1 and Rf4 .

| Title: Fertility restorer locus Rf1 [ corrected ] of sorghum ( Sorghum bicolor L ) encodes a pentatricopeptide repeat protein not present in the colinear region of rice chromosome 12 .
| | Journal: Theor . Appl . Genet . Citation: V : 111 ( 6 ) P : 994-1012 Year: 2005 Type: ARTICLE | | Literature: oryza Field: abstract Doc ID: pub16078015 Accession (PMID): 16078015 | Matching Sentences:
[ Sen. 1, subscore: 1.00 ]: With an aim to clone the sorghum fertility restorer gene Rf1 , a high-resolution genetic and physical map of the locus was constructed .
[ Sen. 2, subscore: 1.00 ]: The Rf1 locus was resolved to a 32-kb region spanning four open reading frames : a plasma membrane Ca ( 2+ ) -ATPase , a cyclin D-1 , an unknown protein , and a pentatricopeptide repeat ( PPR13 ) gene family member .
[ Sen. 6, subscore: 1.00 ]: To permit sequence-based comparison of the sorghum and rice genomes in the Rf1 region , 0 . 53 Mb of sorghum chromosome 8 was sequenced and compared to the colinear region of rice chromosome 12 .
[ Sen. 9, subscore: 1.00 ]: The present results suggest that sorghum PPR13 represents a potential candidate for the sorghum Rf1 gene , and its presence in the sorghum genome indicates a single gene transposition event subsequent to the divergence of rice and sorghum ancestors .

| Title: Cytoplasmic male sterility of rice with boro II cytoplasm is caused by a cytotoxic peptide and is restored by two related PPR motif genes via distinct modes of mRNA silencing .
| | Journal: Plant Cell Citation: V : 18 ( 3 ) P : 676-87 Year: 2006 Type: ARTICLE | | Literature: oryza Field: abstract Doc ID: pub16489123 Accession (PMID): 16489123 | Matching Sentences:
[ Sen. 7, subscore: 4.00 ]: RF1A and RF1B are both targeted to mitochondria and can restore male fertility by blocking ORF79 production via endonucleolytic cleavage ( RF1A ) or degradation ( RF1B ) of dicistronic B-atp6/orf79 mRNA .
[ Sen. 6, subscore: 2.00 ]: Two fertility restorer genes , Rf1a and Rf1b , were identified at the classical locus Rf-1 as members of a multigene cluster that encode pentatricopeptide repeat proteins .
[ Sen. 8, subscore: 2.00 ]: In the presence of both restorers , RF1A was epistatic over RF1B in the mRNA processing .
[ Sen. 9, subscore: 1.00 ]: We have also shown that RF1A plays an additional role in promoting the editing of atp6 mRNAs , independent of its cleavage function .

| Title: Retrograde regulation of nuclear gene expression in CW-CMS of rice .
| | Journal: Citation: V : ( ) P : Year: 2006 Type: ARTICLE | | Literature: oryza Field: abstract Doc ID: pub17086445 Accession (PMID): 17086445 | Matching Sentences:
[ Sen. 5, subscore: 3.00 ]: Five genes , including genes for alternative oxidase , were found to be preferentially expressed in [ cms-CW ] rf17rf17 but not in [ normal ] rf17rf17 or [ cms-CW ] Rf17Rf17 .
[ Sen. 2, subscore: 2.00 ]: The difference between nuclear gene expression in mature anthers was compared for the CW-CMS line , [ cms-CW ] rf17rf17 , and a maintainer line with normal cytoplasm of Oryza sativa L , [ normal ] rf17rf17 .
[ Sen. 6, subscore: 2.00 ]: Such [ cms-CW ] rf17rf17-specific gene expression was only observed in mature anthers but not in leaves , stems , or roots , indicating the presence of anther-specific mitochondrial retrograde regulation of nuclear gene expression , and that Rf17 has a role in restoring the ectopic gene expression .
[ Sen. 1, subscore: 1.00 ]: The CW-cytoplasmic male sterility ( CMS ) line has the cytoplasm of Oryza rufipogon Griff , and mature pollen is morphologically normal under an optical microscope but lacks the ability to germinate ; restorer gene Rf17 has been identified as restoring this ability .

| Title: Suppression mechanism of mitochondrial ORF79 accumulation by Rf1 protein in BT-type cytoplasmic male sterile rice .
| | Journal: Plant J Citation: V : P : Year: 2008 Type: Publisher | | Literature: oryza Field: abstract Doc ID: pub18435825 Accession (PMID): 18435825 | Matching Sentences:
[ Sen. 3, subscore: 1.00 ]: The CMS is restored by a PPR ( pentatricopeptide-repeat ) gene , Rf1 , via RNA processing .
[ Sen. 4, subscore: 1.00 ]: However , it has not yet been elucidated how the accumulation of ORF79 is reduced by the action of the Rf1 protein .
