[ Sen. 4, subscore: 7.00 ]: We used the promoter ( P ( Xa13 ) ) of the dominant Xa13 , which was induced by only the incompatible Xoo strain for xa13 , to regulate xa13 and xa13 ( Leu49 ) ( a natural recessive allele of xa13 ) in the rice line IRBB13 carrying xa13 .
[ Sen. 6, subscore: 6.00 ]: Constitutive expression of dominant XA13 or different xa13 proteins ( xa13 , xa13 ( Leu49 ) , xa13 ( Ala85 ) or xa13 ( Val184 ) ) in IRBB13 had no effect on Xoo infection in the transgenic plants .
[ Sen. 5, subscore: 3.00 ]: The transgenic plants showed the same level of susceptibility and bacterial growth rate as those of the rice line carrying dominant Xa13 , accompanied by the induced accumulation of xa13 or xa13 ( Leu49 ) proteins .
[ Sen. 1, subscore: 2.00 ]: The fully recessive disease resistance ( R ) gene xa13 , which mediates race-specific resistance to Xanthomonas oryzae pv . oryzae ( Xoo ) , encodes a plasma membrane protein that differs by one amino acid from that encoded by its dominant ( susceptible ) allele Xa13 .
[ Sen. 3, subscore: 2.00 ]: Here we show that , compared with its dominant allele , expressional non-reaction of xa13 to Xoo infection , not its protein composition , is the key factor for xa13-mediated resistance .
[ Sen. 2, subscore: 1.00 ]: The molecular mechanism of xa13-mediated resistance is largely unknown .
[ Sen. 7, subscore: 1.00 ]: These results suggest that race-specific pathogen-induced Xa13 expression is critical for infection .
[ Sen. 8, subscore: 1.00 ]: Thus , xa13 stands out from other R genes in that its functions in disease resistance are due to only the loss of pathogen-induced transcriptional motivation caused by natural selection .

[ Sen. 4, subscore: 1.00 ]: The inheritance of Xa10-mediated resistance to PXO99A ( pHM1avrXa10 ) did not follow typical Mendelian inheritance for single dominant gene in F2 population derived from IR24 x IRBB10 .
[ Sen. 7, subscore: 1.00 ]: A new near-isogenic line ( F3-65-1743 ) of Xa10 in IR24 genetic background was developed and designated as IRBB10A .
[ Sen. 9, subscore: 1.00 ]: Linkage analysis using existing RFLP markers and F2 mapping population mapped the Xa10 locus to the proximal side of E1981S with genetic distance at 0 . 93 cM .
[ Sen. 10, subscore: 1.00 ]: With five new RFLP markers developed from the genomic sequence of Nipponbare , Xa10 was finely mapped at genetic distance of 0 . 28 cM between proximal marker M491 and distal marker M419 and co-segregated with markers S723 and M604 .
[ Sen. 12, subscore: 1.00 ]: Seven genes have been annotated from this 74-kb region and six of them are possible Xa10 candidates .
[ Sen. 13, subscore: 1.00 ]: The results of this study will be useful in Xa10 cloning and marker-assisted breeding .

| Title: Characterization of Xanthomonas oryzae-responsive cis-acting element in the promoter of rice race-specific susceptibility gene Xa13 .
| | Author: Yuan T Li X Xiao J Wang S | | Journal: Mol Plant Type: MEDLINE | | Literature: oryza Field: abstract Doc ID: pub21208999 Accession (PMID): 21208999 | Matching Sentences:
[ Sen. 5, subscore: 2.00 ]: In the Xa13 promoter , UPT ( PthXo1 ) box is the only Xoo-responsive cis-acting element that results in PXO99-induced Xa13 expression .
[ Sen. 1, subscore: 1.00 ]: The rice Xa13 gene , whose promoter harbors a UPT ( up-regulated by transcription activator-like [ TAL ] effector ) box , UPT ( PthXo1 ) , plays a pivotal role in the race-specific pathogenicity caused by Xanthomonas oryzae pv . oryzae ( Xoo ) strain PXO99 .
[ Sen. 2, subscore: 1.00 ]: PXO99 causes rice disease by inducing Xa13 .
[ Sen. 3, subscore: 1.00 ]: It is unknown , however , whether the UPT ( PthXo1 ) box is the only PXO99-responsive cis-regulating elements in the activation of Xa13 expression .
[ Sen. 4, subscore: 1.00 ]: We analyzed the expression of a series of end and site-truncated and site-mutated Xa13 promoters in rice and the binding of PXO99 protein to the intact , partial , or site-mutated UPT ( PthXo1 ) boxes .

[ Sen. 2, subscore: 2.00 ]: In order to characterize the genes activated in defense responses against bacterial blight mediated by the recessive R gene xa13 , two pathogen-induced subtraction cDNA libraries were constructed using the resistant rice line IRBB13--which carries xa13--and its susceptible , near-isogenic , parental line IR24 .
[ Sen. 3, subscore: 1.00 ]: Clustering analysis of expressed sequence tags ( ESTs ) identified 702 unique expressed sequences as being involved in the defense responses triggered by xa13 ; 16% of these are new rice ESTs .
