| 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 .
| | Author: Wang Z Zou Y Li X Zhang Q Chen L Wu H Su D Chen Y Guo J Luo D Long Y Zhong Y Liu YG .
| | Journal: Plant Cell Citation: V : 18 ( 3 ) P : 676-87 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 .
| | Author: Fujii S Komatsu S Toriyama K | | Journal: Citation: V : ( ) P : 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: 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 .
| | Author: Klein RR Klein PE Mullet JE Minx P Rooney WL Schertz KF .
| | Journal: Theor . Appl . Genet . Citation: V : 111 ( 6 ) P : 994-1012 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: Characterization of cytoplasmic male sterility of rice with Lead Rice cytoplasm in comparison with that with Chinsurah Boro II cytoplasm .
| | Author: Itabashi E Kazama T Toriyama K | | Journal: Plant Cell Rep Citation: V : 28 P : 233-9 Type: MEDLINE | | Literature: oryza Field: abstract Doc ID: pub18956194 Accession (PMID): 18956194 | Matching Sentences:
[ Sen. 1, subscore: 1.00 ]: Rice with LD-type cytoplasmic male sterility ( CMS ) possesses the cytoplasm of Lead Rice and its fertility is recovered by a nuclear fertility restorer gene Rf1 .
[ 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 .

| 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 .
| | Author: Ohta H Ogino A Kasai M Sano Y Kanazawa A | | Journal: Plant Cell Rep Citation: V : 29 P : 359-69 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 .
