The Pib gene encodes a polypeptide of 1251 amino acids; it contains an NBS region and C-terminal LRRs, but no distinct transmembrane domain. Thus, the Pib gene belongs to the NBS-LRR class of plant disease resistance genes and is predicted to encode a cytoplasmic protein. We speculate that an interaction between the Pib gene product and a ligand specified by the avirulence genes of incompatible rice blast races may occur in the cytoplasm, as predicted for other NBS-LRR plant disease resistance genes.<br /> It is not clear how many members there are in the Pib family. Two members included c23 (Pib) mapped onto chromosome 2 , and the third, cE (PibH8) was mapped onto chromosome 8. The Pib locus comprises a cluster of two homologues contained within the 80 kb region covered by the cosmid contig. <br /> <br /> ===Expression===<br /> There has been only one other report of induced R gene expression. The mRNA for the Xa1 gene for resistance bacterial blight caused by Xanthomonas oryzae pv. oryzae (Xoo) was detected from rice leaves 5 days after wounding or inoculation with either compatible or incompatible strains of Xoo, but was not detected in intact leaves .Pib was expressed at a low level in intact leaves, and increased in expression at 12 and 24 HAI following inoculation with both incompatible and compatible (data not shown) races of rice blast and returned to a low level again at 96 HAI. Like many environmental stress response genes, the Pib gene was induced by altered environmental conditions, such as altered temperatures and darkness. The significance of this induction response to the altered environmental conditions is not clear. The expression of Pib gene remains to be investigated under other environmental stresses, such as wounding, cold treatment, dehydration, etc.<br /> <br /> ==Labs working on this gene==<br /> 1.International Rice Research Institute (IRRI), DAPO Box 7777, Metro Manila, Philippines<br /> 2.Japan International Research Center for Agricultural Sciences (JIRCAS), 1-1, Ohwashi, Tsukuba, Ibaraki 305-8686, Japan<br /> 3.Indonesian Center for Rice Research (ICRR), JL.

Resistance of the Xa27(t) gene was developmentally regulated in IRBB27 and showed semidominant or a dosage effect in the cv. CO39 genetic background. As a prelude to cloning Xa27(t), a molecular mapping strategy was employed with a large mapping population consisting of 3,875 gametes<br /> <br /> ===Evolution===<br /> Induction of Xa27 occurs only in the immediate vicinity of infected tissue, whereas ectopic expression of Xa27 resulted in resistance to otherwise compatible strains of the pathogen. Thus Xa27 specificity towards incompatible pathogens involves the differential expression of the R gene in the presence of the AvrXa27 effector.<br /> <br /> ==Structured Information==<br /> FEATURES Location/Qualifiers<br /> source 1..2361<br /> /organism=&quot;Oryza sativa Indica Group&quot;<br /> /mol_type=&quot;genomic DNA&quot;<br /> /db_xref=&quot;taxon:39946&quot;<br /> /chromosome=&quot;6&quot;<br /> /note=&quot;PstI-ApaI fragment&quot;<br /> gene 1558..1899<br /> /gene=&quot;Xa27&quot;<br /> /allele=&quot;IRBB27&quot;<br /> CDS 1558..1899<br /> /gene=&quot;Xa27&quot;<br /> /allele=&quot;IRBB27&quot;<br /> /codon_start=1<br /> /product=&quot;Xa27&quot;<br /> /protein_id=&quot;AAY54164.1&quot;<br /> /db_xref=&quot;GI:66735944&quot;<br /> /translation=&quot;MADWAMHHYLLLANQQRHRALADVAVRRRQLLLDSGRVFMLLGA<br /> VILMHMLTTTGGGASSGCTRGAEPCVALLLWLLGAALAMLSLVAGRFPVLAAAIAEEL<br /> GDHLLGGLWSL&quot;<br /> ORIGIN <br /> 1 ctgcagctga accaaacagt tttagctcca tcgaagaaag gagttatact gattggaatg<br /> 61 ctctcacagt aaaaaaaaca aggaagtaga gctggatttt agacagttct acaagaagtt<br /> 121 agaactctac caaaattgga attttggatg atggtctttt aaaaactcga ttgcaggaat<br /> 181 aaaattttac ggcttgaaac ttacaaaatg attagaaaag ataacatgcc tcagcgattt<br /> 241 gtaaaaaagt gaacaaataa aaatctacaa taccactaaa ctattgcttt attttgggga<br /> 301 cattgcttac cattgaaaaa acaactaacc gtaaatacga acacccatat caaatatact<br /> 361 atcactgata aaataatcaa ttgtaaattc aagcacacat attagtatag tactttaact<br /> 421 cgattggata gaagaaacct aactaattta agctatgcct cacaacaaaa aggtataaat<br /> 481 tttttaaggc ttcttttttt ttcttgcgtt tgctagttta tgcttttaag atgtttatac<br /> 541 cttttactcc cctcattcac tgtttaaata caatgggaat tagtgaaatc aatgagagtt<br /> 601 caaacttcga aacactgaat acatgttatt ttggattgaa atcaaatcga atcagtcaaa<br /> 661 ttcaaatagg aggaggaaca taggcattct tcctttcttc agcgggcacc attgaattca<br /> 721 gatactgctt cgcctagtct ctgtccaaga ctccacattt tctgatggtg atggggaact<br /> 781 ctgaaactat aggaggaaga ataaaatgaa gaatgcagaa atgaatagta atttgtgttt<br /> 841 tttaattctt cttcaattcc accttaggat ccaacttcag tccaaatcca aagtaatgca<br /> 901 actgccacta gatcaggcta gagcttcaaa ttcaactcca aaaacctccg taaagtggca<br /> 961 cacacagagg aaaaatcctg gattcgtcac tgcccatcaa catctgcttt cgcctcccaa<br /> 1021 ttcctgcttt ctgaaatctg ctttcgccga attcatgcct tcttgaatta tgctttctta<br /> 1081 gaccctcttt agatgggact aaaactttta ctctctatca catcggatgt ttggacacta<br /> 1141 attataaata ttaaacgtag actattaata aaacccatct ataatcttgt attaattcgc<br /> 1201 gagacgaatc tattgagcct aattaatcca tgattagcct atgtgatgct ataataaaca<br /> 1261 ttctctaatt ataaattaat tgggcttaaa aaatttgtct cgcgtattag ctttcattta<br /> 1321 tataattagt tttataaata gtctatattt aatactctaa attagtgtct aaatacaggg<br /> 1381 actaaagtta agtcactgga tccaaacacc acctaaggtt ttcttgtgta cttgtgaatt<br /> 1441 gtggttgact acgactacta gtgctataaa tagaagaaga gacccataga gagcatcaga<br /> 1501 gcaaagtact cctaaaagac agccacacac actgagacac ccaagaagct gcctccaatg<br /> 1561 gcggattggg cgatgcacca ctacctccta ctagccaacc agcaacgcca ccgagccctc<br /> 1621 gccgacgtcg ccgtccgccg ccgccagctg ctcctcgact ccggccgcgt cttcatgctc<br /> 1681 ctcggcgccg tcatcctcat gcacatgctc accactaccg gcggcggagc atcgtccggc<br /> 1741 tgcacccgcg gcgccgaacc ttgcgtcgcc ctcctcctgt ggctgctcgg cgcggcgctc<br /> 1801 gccatgctgt cgctcgtcgc cggccgattc cccgttctcg ctgccgccat tgctgaggag<br /> 1861 ctcggtgatc acctgcttgg tggtctctgg tctctctagt tctcctccgt gtccggtggt<br /> 1921 catcttcttc tccgtgcttt tgctctggag ttgagtacgg atctgtgtgt actgcattct<br /> 1981 tgcttaatta gtgccctaca cgttatgctt tcgaaacatc atcttttttc agtatagttc<br /> 2041 aataaatttc agctcaaatt tgtcctccaa gacgagttct ccatccaaac gaaacttatg<br /> 2101 gtgttccgtt gtttgggccg attttatatg ttggaaatgt acagacttca tagtactgtg<br /> 2161 tttctttttt ggaataagtt caccagaggt tccttaactt aacggcgata tttttttagg<br /> 2221 tcctttaacc acaaaaccag aaatgtgcac ccctaaactt tcacaatccg tgcacaagag<br /> 2281 gtcctatggc agtatacgtg ggtggtttcg ctgacgtgac atcctagtca gcaaaaataa<br /> 2341 ataaataagt aagtggggcc c<br /> //<br /> <br /> ==Labs working on this gene==<br /> 1.
