      背景技術(shù)
      :微絲解聚因子(ADF/cofilin)廣泛存在于真核細(xì)胞中,對(duì)維持細(xì)胞的形態(tài)結(jié)構(gòu)、細(xì)胞運(yùn)輸、能量轉(zhuǎn)換、信息傳遞、細(xì)胞分裂及分化等起著非常重要的作用。前期研究表明,擬南芥微絲解聚因子ADF1表達(dá)量變化會(huì)影響植物的開花期,ADF1表達(dá)量的降低導(dǎo)致開花延遲。野生型擬南芥約在35±1天開花,有17片蓮座葉;而ADF1基因沉默植株開花較野生型延遲2周,蓮座葉數(shù)目增加至26片。其后,人們通過基因敲除深入解析ADF在植物生長發(fā)育中的分子功能。擬南芥adf4突變體具有更長的下胚軸和表皮細(xì)胞。擬南芥ADF9的突變體(adf9-1,adf9-2)植株的頂端優(yōu)勢(shì)增強(qiáng),其花序的二級(jí)分枝數(shù)目少于野生型,但分枝的長度比野生型長;長日照生長條件下突變體開花時(shí)間早于野生型,同時(shí)蓮座葉數(shù)目比野生型少,而短日照生長條件下跟野生型相比沒有明顯差異。此外,ADF9能調(diào)控開花轉(zhuǎn)換時(shí)期相關(guān)基因的表達(dá)量。這些研究表明,ADF蛋白直接參與植物生長發(fā)育及花期調(diào)控,但其調(diào)控的目標(biāo)基因、參與的關(guān)鍵調(diào)控因子及分子調(diào)控機(jī)制等都不清楚。技術(shù)實(shí)現(xiàn)要素:本發(fā)明提供了擬南芥基因REM16的表達(dá)載體及其在調(diào)控植株開花期中的應(yīng)用。本發(fā)明以擬南芥ADF1為誘餌,通過酵母雙雜交從擬南芥cDNA文庫中篩選得到了十幾個(gè)ADF1互作蛋白分子,獲得本發(fā)明所述的基因REM16(基因編號(hào)為AT3G53310),并通過實(shí)驗(yàn)證明了其調(diào)控?cái)M南芥花期的功能。為實(shí)現(xiàn)上述發(fā)明目的,本發(fā)明采用以下技術(shù)方案予以實(shí)現(xiàn):本發(fā)明提供了一種擬南芥基因REM16的過表達(dá)載體pCambia1300-221-HA,所述過表達(dá)載體pCambia1300-221-HA的核苷酸序列如序列表SEQIDNo:2所示,所述過表達(dá)載體含有如序列表SEQIDNo:1所示的基因REM16,所述過表達(dá)載體pCambia1300-221-HA用于調(diào)控?cái)M南芥花期提前。進(jìn)一步的:將基因REM16和帶有XbaI和KpnI酶切位點(diǎn)的pCambia1300-221-HA載體分別進(jìn)行KpnI和XbaI的雙酶切,再按照基因片段和載體4:1的比例在T4連接酶的催化下進(jìn)行16℃過夜連接20h制得。本發(fā)明提供了一種擬南芥基因REM16的基因沉默載體pB7GWIWG2(II).0,所述基因沉默載體pB7GWIWG2(II).0的核苷酸序列如序列表SEQIDNo:3所示,所述基因沉默載體pB7GWIWG2(II).0用于調(diào)控?cái)M南芥花期延遲。本發(fā)明還提供了擬南芥基因REM16在調(diào)控?cái)M南芥開花期中的應(yīng)用。進(jìn)一步的:所述調(diào)控開花期的擬南芥中含有如序列表SEQIDNo:1所示的過表達(dá)載體pCambia1300-221-HA或如序列表SEQIDNo:2所示的基因沉默載體pB7GWIWG2(II).0。進(jìn)一步的:所述擬南芥基因REM16具有花期調(diào)控的功能,基因REM16過表達(dá)植株表現(xiàn)為早花性狀,基因REM16沉默植株表現(xiàn)為晚花性狀。進(jìn)一步的:所述基因REM16過表達(dá)植株開花時(shí)間比野生型植株早4-6天,蓮座葉數(shù)目比野生型少2片;而所述基因REM16沉默植株開花時(shí)間比野生型植株晚2-3天,蓮座葉數(shù)目和野生型沒有顯著變化。進(jìn)一步的:所述基因REM16過表達(dá)植株中涉及光周期途徑GI、CO以及開花下游的開花整合子和花分生組織決定基因FT、LFY、AP1的表達(dá)量均高于野生型植株,春化途徑FLC的表達(dá)量低于野生型植株,赤霉素途徑RGA、RGL1的表達(dá)量與野生型比沒有明顯差異。進(jìn)一步的:所述基因REM16沉默植株中涉及光周期途徑GI、CO以及開花下游的開花整合子和花分生組織決定基因FT、LFY、AP1的表達(dá)量均低于野生型植株,春化途徑FLC的表達(dá)量高于野生型植株,赤霉素途徑RGA、RGL1的表達(dá)量與野生型比沒有明顯差異。本發(fā)明的優(yōu)點(diǎn)和有益效果:利用現(xiàn)有的植物基因工程技術(shù),本發(fā)明通過花序侵染法的方法獲得擬南芥基因REM16的過表達(dá)和基因沉默轉(zhuǎn)基因載體及其轉(zhuǎn)基因株系,通過研究過表達(dá)和基因沉默轉(zhuǎn)基因植株表型,并將其與相同條件下生長的野生型植株開花時(shí)間及蓮座葉數(shù)目進(jìn)行比較。經(jīng)過實(shí)驗(yàn)分析證明,擬南芥基因REM16(AT5G25520)具有花期調(diào)控的功能,過表達(dá)REM16基因引起轉(zhuǎn)基因擬南芥植株中開花相關(guān)基因表達(dá)變化而促進(jìn)擬南芥提早開花,與野生型植株的開花時(shí)間相比表現(xiàn)為早花性狀;沉默REM16基因引起轉(zhuǎn)基因擬南芥植株中開花相關(guān)基因表達(dá)變化而延遲擬南芥開花,與野生型植株相比表現(xiàn)為晚花性狀。通過分析轉(zhuǎn)基因株系開花相關(guān)基因的表達(dá)從而確定REM16基因調(diào)控開花的功能。本發(fā)明的技術(shù)方案對(duì)于植物花期調(diào)控具有重要意義。附圖說明圖1為野生型與突變體REM16基因表達(dá)量分析(**:P<0.01)。圖2為野生型與突變體開花時(shí)間及蓮座葉比較,其中:(a)為野生型與突變體開花時(shí)間比較;(b)為野生型與突變體開花時(shí)間統(tǒng)計(jì)分析;(c)為野生型與突變體蓮座葉數(shù)目統(tǒng)計(jì)分析(**:P<0.01)。圖3為野生型與突變體開花相關(guān)基因表達(dá)量分析(**:P<0.01)。具體實(shí)施方式下面結(jié)合附圖和具體實(shí)施例來對(duì)本發(fā)明的技術(shù)方案做進(jìn)一步詳細(xì)的說明。本發(fā)明實(shí)驗(yàn)中用到的試劑等購自TAKARA、Promega、Sigma等公司。實(shí)驗(yàn)中用到的LB培養(yǎng)基配方:0.5%酵母粉、1%NaCl、1%蛋白胨。其它試劑配方:見《分子克隆》第三版。實(shí)施例1、REM16基因的克隆1、擬南芥的種植擬南芥種子的表面消毒:將50粒待滅菌的擬南芥種子放入1.5ml離心管中,加入1ml75%的乙醇(含有0.03%體積比的TritonX-100)震蕩消毒1min,再用70%的乙醇震蕩消毒1min(兩次),最后用吸頭將種子吸到無菌濾紙上吹干,然后用無菌的牙簽將其點(diǎn)入1/2MS培養(yǎng)基中,冰箱中4℃春化3d后取出置于光照培養(yǎng)箱中培養(yǎng)。培養(yǎng)條件如下:16h光照/8h黑暗交替光照,溫度22℃,光強(qiáng)100μmol·m-2·s-1。然后,待光照生長7-10天將擬南芥幼苗移到土中,覆蓋保鮮膜3-7天揭膜,后于培養(yǎng)室中培養(yǎng),條件同光照培養(yǎng)箱。2、擬南芥總RNA提取(1)將擬南芥材料放入預(yù)冷的研缽中,加入液氮迅速研磨成均勻的粉末。注意研磨過程中要保證材料浸在液氮中;(2)等液氮揮發(fā)后,立即將100-200mg植物粉末轉(zhuǎn)入到1.5ml離心管中,然后迅速加入1mlTrizol提取液,渦旋震蕩使樣品充分溶入提取液中,室溫放置5min;(3)4℃,12,000rpm,離心11min,將0.8ml上清液轉(zhuǎn)移到新的1.5ml離心管中;再加入0.2ml氯仿劇烈振蕩混勻15sec,室溫放置2-5min直到分層。(4)4℃,12,000rpm,離心11min,將0.4ml上清液轉(zhuǎn)移到新的1.5ml離心管中;再加入0.4ml異丙醇,上下翻轉(zhuǎn)15次混勻溶液,-20℃放置30mim。(5)4℃,12,000rpm,離心11min,棄上清,用0.9ml75%的乙醇洗滌沉淀兩次,4℃,12,000rpm,離心5min;(6)棄上清,開蓋于超凈工作臺(tái)中干燥RNA約2-5min,加入40μlRNase-Free水,在60℃中充分溶解RNA10min;(7)用紫外分光光度計(jì)測RNA樣品的OD值和濃度,A260/A280達(dá)到1.8-2.0為佳;瓊脂糖凝膠電泳檢測的質(zhì)量。3、RNA的反轉(zhuǎn)錄詳見TaKaRa的PrimeScriptTMRTreagentKitwithgDNAEraser試劑盒(RR047A)說明書。4、PCR擴(kuò)增以上述反轉(zhuǎn)錄合成的cDNA為模板,PCR法擴(kuò)增基因片段。(1)PCR引物由上海桑尼生物技術(shù)服務(wù)有限公司合成:引物REM16-For:5’-ATGGCTGACGATAGCGAAT-3’(SEQIDNo:4);引物REM16-Rev:5’-TCAAGCATCTCTACGCAAGACATG-3’(SEQIDNo:5)。(2)PCR反應(yīng)體系組分體積(μl)/管10×PCRBuffer2.5dNTPMixture1擬南芥cDNA3正向引物(10μΜ)1反向引物(10μΜ)1rTaq0.15ddH2O18.5總體積25PCR反應(yīng)條件:94oC預(yù)變性5min;94oC變性30s,62oC退火30s,72oC延伸50s,27個(gè)循環(huán);72oC延伸7min。5、PCR產(chǎn)物回收PCR反應(yīng)后1%的瓊脂糖凝膠電泳檢測(110V17min),后在凝膠成像儀上觀察結(jié)果并拍照。然后參照TaKaRaMiniBESTAgaroseGelDNAExtractionKitVer.4.0試劑盒說明書將PCR產(chǎn)物回收,回收到擬南芥基因REM16(AP2/B3-liketranscriptionalfactorfamilyprotein),所述基因REM16CDS序列如序列表SEQIDNo:1所示。6、連接將以上回收得到的REM16基因片段通過TA克隆連接到克隆載體pMD18-TVector上,16oC過夜。連接體系如下:組分體積(μl)/管SolutionI5pMD18-TVector1DNA回收產(chǎn)物4總體積107、大腸桿菌DH5α感受態(tài)細(xì)胞的制備和轉(zhuǎn)化大腸桿菌DH5α感受態(tài)細(xì)胞的制備(1)DH5α菌種的活化:從-80℃超低溫冰箱中取出保存的DH5α菌種,劃線后37℃倒置培養(yǎng);(2)挑取單菌落接種于10mLLB(-)液體培養(yǎng)基中,37℃,200rpm過夜培養(yǎng)12h;(3)按1:100取接種于50mlLB液體培養(yǎng)基中,37℃,200rpm培養(yǎng)至OD600值為0.4-0.6;(4)將菌液轉(zhuǎn)移至50mL離心管中,冰上放置10min,4℃,2500
