| Author: Jiang GH Xia ZH Zhou YL Wan J Li DY Chen RS Zhai WX Zhu LH .
| Journal: Citation: V : ( ) P : 1-13 Year: 2006 Type: ARTICLE | Literature: oryza Field: abstract Doc ID: pub16444514 Accession (PMID): 16444514 | Matching Sentences: [ Sen. 2, subscore: 5.00 ]: However , xa5 has not been demonstrated by a complementation test In this study , we introduced the dominant allele Xa5 into a homozygous xa5-line , which was developed from a cross between IRBB5 ( an indica variety with xa5 ) and Nipponbare ( a japonica variety with Xa5 ) . [ Sen. 3, subscore: 3.00 ]: Transformation of Xa5 and subsequent segregation analysis confirmed that xa5 is a V39E substitution variant of the gene for TFIIAgamma on chromosome 5 ( TFIIAgamma5 or Xa5 ) . [ Sen. 8, subscore: 2.00 ]: The modeled structures of Xa5 ( xa5 ) and TFIIAgamma1 fit well with the structure of TFIIA small subunit from human , suggesting that they may all act as a small subunit of TFIIA . [ Sen. 10, subscore: 2.00 ]: The structural analysis indicates that xa5 and Xa5 potentially retain their basic transcription factor function , which , in turn , may mediate the novel pathway for bacterial blight resistance and susceptibility , respectively . [ Sen. 1, subscore: 1.00 ]: The recessive gene xa5 for resistance to bacterial blight resistance of rice is located on chromosome 5 , and evidence based on genetic recombination has been shown to encode a small subunit of the basal transcription factor IIA ( Iyer and McCouch in MPMI 17 ( 12 ) : 1348-1354 , 2004 ) . [ Sen. 5, subscore: 1.00 ]: Analysis of the expression patterns of Xa5 ( TFIIAgamma5 ) /xa5 and TFIIAgamma1 revealed that both the genes are constitutively expressed in different rice organs . [ Sen. 9, subscore: 1.00 ]: The E39V substitution in the xa5 protein occurs in the alpha-helix domain , a supposed conservative substitutable site , which should not affect the basal transcription function of TFIIAgamma .

[ Sen. 3, subscore: 2.00 ]: The V39E substitution in OsTFIIAgamma5 , encoded by the recessive resistance gene xa5 in rice , greatly attenuates this activation in xa5 and Xa27 double homozygotes on inoculation with Xa27-incompatible strains . [ Sen. 9, subscore: 2.00 ]: The identification of xa5-mediated attenuation of Xa27-mediated resistance to Xoo provides a guideline for breeding resistance to BB when pyramiding xa5 with other resistance genes . [ Sen. 4, subscore: 1.00 ]: The xa5 gene also causes attenuation in the induction of Xa27 by AvrXa27 expressed in rice . [ Sen. 5, subscore: 1.00 ]: The xa5-mediated attenuation of Xa27-mediated resistance to PXO99 ( A ) is recessive . [ Sen. 7, subscore: 1.00 ]: In addition , AvrXa27 expressed in planta shows weak virulence activity in the xa5 genetic background and causes enhanced susceptibility of the plants to BB inoculation .

| Author: Iyer-Pascuzzi AS Jiang H Huang L McCouch SR | Journal: Phytopathology Citation: V : 98 P : 289-95 Year: 2008 Type: In-Process | Literature: oryza Field: abstract Doc ID: pub18944079 Accession (PMID): 18944079 | Matching Sentences: [ Sen. 4, subscore: 2.00 ]: Here we show that xa5 is inherited in a completely recessive manner and the susceptible allele Xa5 is fully dominant . [ Sen. 2, subscore: 1.00 ]: The gene xa5 provides race-specific resistance to X oryzae pv . oryzae , and encodes the small subunit of transcription factor IIA . [ Sen. 3, subscore: 1.00 ]: How xa5 functions in bacterial blight resistance is not well understood , and its recessive gene action is disputed . [ Sen. 6, subscore: 1.00 ]: Further , one allele of Xa5 is sufficient to promote disease in previously resistant plants ; additional copies are not predictive of increased lesion length . [ Sen. 10, subscore: 1.00 ]: These results support a model in which xa5-mediated recessive resistance is the result of restricted bacterial movement , but not restricted multiplication .
