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 .

| 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 .

| 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 .

Score: 8.00 | 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 .

[ Sen. 2, subscore: 1.00 ]: Rf1 promotes processing of a CMS-associated mitochondrial RNA of atp6-orf79 , which consists of atp6 and orf79 , in BT-CMS with the cytoplasm of Chinsurah Boro II . [ Sen. 4, subscore: 1.00 ]: Northern blot analysis showed that atp6-orf79 RNA of LD-cytoplasm was co-transcribed and was processed in the presence of Rf1 in the same manner as in BT-cytoplasm . [ Sen. 5, subscore: 1.00 ]: Western blot analysis showed that the ORF79 peptide did not accumulate in an LD-CMS line , while ORF79 accumulated in a BT-CMS line and was diminished by Rf1 .

Score: 4.00 | Title: Fertility restoration by Ifr1 in rice with BT-type cytoplasmic male sterility is associated with a reduced level , but not processing , of atp6-orf79 co-transcribed RNA .
| Journal: Plant Cell Rep Citation: V : 29 P : 359-69 Year: 2010 Type: MEDLINE | Literature: oryza Field: abstract Doc ID: pub20195612 Accession (PMID): 20195612 | Matching Sentences: [ Sen. 2, subscore: 1.00 ]: The male-sterile state of BT-type CMS is stably maintained by backcrossing the plants with line Taichung 65 ( T65 ) that has no restorer gene and is completely suppressed by the presence of the Rf1 gene through the processing of B-atp6-orf79 RNA . [ Sen. 3, subscore: 1.00 ]: A variant of the T65 line , T65 ( T ) , has a weak restoration function conferred by the Ifr1 gene , which is genetically independent of the Rf1 gene . [ Sen. 5, subscore: 1.00 ]: In a study to examine whether the mechanism involved in fertility restoration by Ifr1 is analogous to restoration mediated by Rf1 , the transcript profile of B-atp6-orf79 in male-sterile plants was compared with that in fertility restored plants obtained by crossing male-sterile plants with T65 ( T ) . [ Sen. 7, subscore: 1.00 ]: These results suggest that Ifr1 restores fertility through reducing either the transcription rate of B-atp6-orf79 or the stability of its primary transcripts , a mechanism distinct from that involved in fertility restoration of BT-type CMS by Rf1 .
