摘要 Thepromoterregionofadroughtandabscisicacid(ABA)induciblegene,osr40c1,wasisolatedfromasalt-tolerantindicaricevarietyPokkali,whichis670bpupstreamoftheputativetranslationstartcodon.Insilicopromoteranalysisofresultedsequenceshowedthatatleast15typesofputativemotifsweredistributedwithinthesequence,includingtwotypesofcommonpromoterelements,TATAandCAATboxes.Additionally,severalputativecis-acingregulatoryelementswhichmaybeinvolvedinregulationofosr40c1expressionunderdifferentconditionswerefoundinthe5′-upstreamregionofosr40c1.TheseareABA-responsiveelement,light-responsiveelements(ATCT-motif,BoxI,G-box,GT1-motif,Gap-boxandSp1),myeloblastosisoncogeneresponseelement(CCAAT-box),auxinresponsiveelement(TGA-element),gibberellin-responsiveelement(GARE-motif)andfungal-elicitorresponsiveelements(BoxEandBox-W1).Aputativeregulatoryelement,requiredforendosperm-specificpatternofgeneexpressiondesignatedasSkn-1motif,wasalsodetectedinthePokkaliosr40c1promoterregion.Inconclusion,thebioinformaticanalysisofosr40c1promoterregionisolatedfromindicaricevarietyPokkaliledtotheidentificationofseveralimportantstress-responsivecisactingregulatoryelements,andtherefore,theisolatedpromotersequencecouldbeemployedinricegenetictransformationtomediateexpressionofabioticstressinducedgenes.
