收稿日期20140709在眾多的轉(zhuǎn)錄因子中,WRKY轉(zhuǎn)錄因子是當(dāng)前研究較為廣泛的植物特有的轉(zhuǎn)錄因子,最初是從甜馬鈴薯[1]、野燕麥[2]、歐芹[3]和擬南芥[4]中克隆獲得,由于其蛋白含有高度保守的60個(gè)氨基酸組成的WRKY結(jié)構(gòu)域而將其命名為WRKY轉(zhuǎn)錄因子[5]。WRKY結(jié)構(gòu)域的核心序列靠近氨基(N)末端,由WRKYGQK等7個(gè)保守的氨基酸殘基組成,能夠與基因啟動(dòng)子中的(T)(T)TGAC(C/T)序列(W盒)發(fā)生特異性結(jié)合,從而調(diào)節(jié)基因的表達(dá),參與多種與植物生長(zhǎng)發(fā)育、脅迫應(yīng)答和物質(zhì)代謝等有關(guān)的重要生理過(guò)程;而鋅指結(jié)構(gòu)位于羧基(C)末端。根據(jù)WRKY轉(zhuǎn)錄因子中WRKY結(jié)構(gòu)域的個(gè)數(shù)以及鋅指的類型將其分為3個(gè)大組。1.1試驗(yàn)材料一年生吉爾吉斯白樺(Betula kirghisorum)葉片。

1.2.4序列相似性分析及進(jìn)化樹(shù)的構(gòu)建。采用BlastP尋找相似性序列,并選擇與其相似性高的10種不同植物WRKY蛋白的氨基酸序列,采用ClustalW2(http://www.ebi.ac.uk/Tools /msa/ clustalw2/)進(jìn)行多序列比對(duì);同時(shí)用MEGA6軟件構(gòu)建上述11種植物WRKY蛋白的氨基酸序列系統(tǒng)進(jìn)化樹(shù)。

1.2.50.6% NaHCO3脅迫處理前后基因表達(dá)量的分析?;虮磉_(dá)量的計(jì)算使用RPKM法[8],以RPKM值估計(jì)BkWRKY1基因的表達(dá)量,基因表達(dá)量符合FDR≤0.001,且log2Ratio|≥1的基因?yàn)轱@著差異表達(dá)基因。其中,Ratio為脅迫處理后RPKM值與對(duì)照組RPKM值的比值,log2Ratio為0.6%NaHCO3脅迫處理后BkWRKY1基因相對(duì)于對(duì)照組BkWRKY1基因表達(dá)量的變化。

2結(jié)果與分析

2.1吉爾吉斯白樺BkWRKY1基因序列與推斷的氨基酸序列從鹽脅迫后的吉爾吉斯白樺葉片轉(zhuǎn)錄組文庫(kù)中測(cè)序獲得了BkWRKY1基因的cDNA序列,測(cè)序結(jié)果顯示,該基因cDNA包含2 189個(gè)堿基,序列比對(duì)和同源性分析表明,該基因cDNA序列包含1 728 bp的開(kāi)放閱讀框,編碼575個(gè)氨基酸,5′非翻譯區(qū)(UTR)為119 bp,3′非翻譯區(qū)(UTR)為342 bp。ProtParam 預(yù)測(cè)該蛋白的分子量為62.483 kD,理論等電點(diǎn)為7.32,負(fù)電荷殘基(Asp+Glu)總數(shù)為62個(gè),正電荷殘基(Arg+Lys)總數(shù)是62個(gè)。

2.2蛋白家族、保守區(qū)及二級(jí)結(jié)構(gòu)預(yù)測(cè)對(duì)獲得的基因推導(dǎo)的氨基酸序列用BlastP預(yù)測(cè)蛋白保守區(qū),發(fā)現(xiàn)了WRKY結(jié)構(gòu)域,位于227~285、402~461氨基酸之間含有WRKY蛋白的保守序列,pfam蛋白預(yù)測(cè)表明,與其對(duì)應(yīng)的蛋白質(zhì)家族WRKY DNA-domain family,以上分析表明該基因?qū)儆赪RKY transcription factor家族。SOPMA軟件預(yù)測(cè)結(jié)果表明BkWRKY1蛋白的二級(jí)結(jié)構(gòu)以隨機(jī)卷曲為主。注:ATG為起始密碼子;*為終止密碼子。

圖2BkWRKY1基因的cDNA序列及由此推導(dǎo)的氨基酸序列2.3信號(hào)肽、疏水性及跨膜結(jié)構(gòu)分析通過(guò)signalp 4.1預(yù)測(cè),該蛋白不含有信號(hào)肽。ProScal蛋白親水、疏水性預(yù)測(cè)表),蛋白疏水性最大值:1.789,疏水性最小值:-3.389,疏水平均值為-0.800,具有一定的親水性。并根據(jù)ProtParam軟件預(yù)測(cè)Grand average of hydropathicity(GRAVY):-0.777,所以該蛋白質(zhì)為親水蛋白。TMHMM程序預(yù)測(cè)結(jié)果表明,在BkWRKY1長(zhǎng)度為575個(gè)氨基酸的蛋白序列中無(wú)跨膜結(jié)構(gòu)。

2.4吉爾吉斯白樺等物種BkWRKY1基因的多序列比對(duì)分析用推導(dǎo)的氨基酸序列與蛋白質(zhì)數(shù)據(jù)庫(kù)進(jìn)行同源性比較,其氨基酸序列與川桑(Morus notabilis,EXB67429.1)、煙草(Theobroma cacao,XP_007020620.1)、蓖麻(Ricinus communis、XP_002529048.1)、甜橙(Citrus sinensis,XP_006474948.1)、草莓(Fragaria vesca,XP_004294460.1)、大豆(Glycine max,XP_003553015.1)、葡萄(Vitis vinifera,XP_002274204.2)、麻風(fēng)樹(shù)(Jatropha curcas,AGJ52155.1)、楊樹(shù)(Populus trichocarpa,XP_002298853.1)、蒺藜苜蓿(Medicago truncatula,XP_ 003600259.1)等植物WRKY轉(zhuǎn)錄因子的氨基酸序列進(jìn)行兩兩比對(duì),相似系數(shù)分別為72%、71%、70%、69%、69%、68%、68%、68%、66%、66%,相似性較高。氨基酸序列多重比對(duì)結(jié)果用MEGA6軟件對(duì)該基因及其他物種WRKY轉(zhuǎn)錄因子的氨基酸序列進(jìn)行多序列比對(duì),繪制分子進(jìn)化樹(shù),進(jìn)化分析結(jié)果表明,吉爾吉斯白樺WRKY蛋白與大豆和蒺藜苜蓿的WRKY蛋白在進(jìn)化上關(guān)系較近。

疏水性分析42卷23期田玉富等吉爾吉斯白樺BkWRKY1基因克隆與序列分析2.50.6% NaHCO3脅迫處理后BkWRKY1基因的表達(dá)量測(cè)得BkWRKY1基因?qū)φ战M和脅迫處理后的RPKM值分別為19.803 1和23.622 4,log2Ratio為0.254 4,表明該基因在0.6% NaHCO3脅迫處理后表達(dá)量增加,為上調(diào)表達(dá)基因(圖8)。

3結(jié)論與討論

以白樺轉(zhuǎn)錄組文庫(kù)獲得的基因序列為信息來(lái)源,從中克隆得到了白樺BkWRKY1基因,屬于WRKY family transcription factor家族,該基因含有2個(gè)WRKY結(jié)構(gòu)域,可編碼575個(gè)氨基酸,對(duì)應(yīng)蛋白的分子量為62.483 kD,理論等電點(diǎn)為7.32,蛋白不含有信號(hào)肽,具有一定的親水性,為親水蛋白,不含有跨膜結(jié)構(gòu)。同源性比較與進(jìn)化樹(shù)分析表明,吉爾吉斯白樺WRKY蛋白與大豆和蒺藜苜蓿的WRKY蛋白在進(jìn)化關(guān)系上較近。0.6%NaHCO3脅迫處理后BkWRKY1基因上調(diào)表達(dá)。

WRKY轉(zhuǎn)錄因子在植物界中分布廣泛,目前,發(fā)現(xiàn)辣椒[9]、油菜[10]、玉米[11]、番木瓜[12]、苜蓿[13]、楊樹(shù)[14]、蘋(píng)果[15]、森林草莓[16]、水稻[17]等多個(gè)種屬植物中均含有WRKY轉(zhuǎn)錄因子。WRKY轉(zhuǎn)錄因子參與植物的多種生理生化與生長(zhǎng)發(fā)育過(guò)程,在植物應(yīng)對(duì)外界逆境脅迫時(shí)發(fā)揮十分重要的功能。如參與側(cè)根的生長(zhǎng)[18-20],調(diào)控衰老反應(yīng)[21-23],調(diào)控新陳代謝[24-25],抑制種子的萌發(fā)[26-29],調(diào)控非生物脅迫[30-33],參與生物脅迫[34-49],參與抗病相關(guān)信號(hào)轉(zhuǎn)導(dǎo)途徑[50-55]。在鹽脅迫條件下,許多植物組織器官中的WRKY基因能夠作出積極的響應(yīng),上調(diào)或下調(diào)表達(dá)。QIU等[56]研究水稻中13個(gè)WRKY基因,指出其中9個(gè)基因能對(duì)NaCl做出響應(yīng);研究發(fā)現(xiàn)擬南芥可以忍受150 mmol/L NaCl脅迫,脅迫處理后WRKY17和WRKY33上調(diào)表達(dá),WRKY17在誘導(dǎo)脅迫6h時(shí)達(dá)最高峰隨后逐漸降低,而WRKY33的豐度在整個(gè)處理過(guò)程都保持很高;處理48h時(shí)WRKY25表達(dá)至最高峰,WRKY轉(zhuǎn)錄因子在鹽脅迫反應(yīng)中具有重要作用[57]。150 mmol/L NaCl脅迫下,小麥根中WRKY基因表達(dá)量隨脅迫時(shí)間的延長(zhǎng)而逐漸增加;莖中WRKY基因在脅迫1 h時(shí)達(dá)到最大值,而隨脅迫時(shí)間的延長(zhǎng)逐漸下降,由此可知對(duì)于鹽脅迫,其根比莖敏感[58]。 珠美海棠幼苗在150 mmol/L NaCl脅迫處理后,MzWRKY19~MzWRKY27等共8個(gè)基因的表達(dá)無(wú)明顯變化;葉片中有15個(gè)WRKY基因的表達(dá)受鹽脅迫誘導(dǎo)、1個(gè)基因受鹽脅迫抑制、9個(gè)基因的表達(dá)無(wú)明顯變化[59]。200 mmol/L NaCl能強(qiáng)烈誘導(dǎo)MhWRKY40b表達(dá),且脅迫6h時(shí)基因相對(duì)表達(dá)量達(dá)到最高,說(shuō)明MhWRKY40b能夠響應(yīng)鹽脅

圖6氨基酸序列的多重比對(duì)圖7白樺等11個(gè)物種的WRKY序列的系統(tǒng)進(jìn)化樹(shù)圖80.6%NaHCO3脅迫處理后BkWRKY1基因的表達(dá)量迫,并有可能在鹽脅迫反應(yīng)中起到了重要調(diào)控作用[60]。

吉爾吉斯白樺BkWRKY1能夠?qū)?.6%NaHCO3脅迫作出上調(diào)表達(dá)的響應(yīng),但具體的響應(yīng)機(jī)制還不清楚。因此,有待于進(jìn)一步研究鹽脅迫條件下吉爾吉斯白樺BkWRKY1基因及WRKY家族其他成員在抗鹽過(guò)程中的功能,為選育抗鹽堿的樺樹(shù)品種提供試驗(yàn)依據(jù)。
