Abstract:【Objective】To conduct transcriptome sequencing analysis on Sesuvium portulacastrum under salt tole-rance, and to find out genes related to salt tolerance in the root of S. portulacastrum, so as to provide reference for studying molecular mechanism of S. portulacastrum. 【Method】Illumina sequencing technology was applied to compare and analyze the transcriptomesand the differentially expressed genes (DEGs) related to salt tolerance inroots of S. portulacastrum under 0 mmol/L NaCl (control group) and 400 mmol/L NaCl salt stress (salt stress treatment group),respectively. Thirteen DEGs were selected to verify the reliability of transcriptome data by using quantitative real-time PCR(qRT-PCR) analysis. 【Result】 A total of 305145 transcripts with an average length of 622 bp were identified in the roots of S. portulacastrum transcriptome. In the control group, 146177 transcripts were greater than 300 bp; in the salt treatment group,72173 transcripts were greater than 300 bp. A total of 65535 unigenes were successfully annotated in the five databases of Nr, GO, Swiss-Prot, COG and KEGG, accounting for 52.36% of the total unigenes and including 182 heat shock protein genes. A number of 24042 DEGs between the control group and the salt stress treatment group were identified. Thirteen candidate genes were selected for qRT-PCR analysis, and the result showed that 9 genes were up-regulated and 4 genes were down-regulated, which was consistent with transcriptome sequencing analysis. Among the 24042 DEGs,10106 significant DEGs were enriched in 129 metabolic pathways. The top 10 enriched metabolic pathways were ribosome, biosynthesis of secondary metabolites, RNA transport, endocytosis, spliceosome, glycerophospholipid metabolism, protein processing in endoplasmic reticulum, phagocytosis, ether lipid metabolism and plant-pathogen interaction path. Differential genes in sulfur metabolism, proline accumulation, eactive oxygen species(ROS) metabolism, calcium signaling pathway and hydrogen peroxide metabolism related to salt stress were up-regulated. 【Conclusion】Under salt stress,DEGs in S. portulacastrum, such as small molecular heat shock protein genes, genes related to anti-oxidation and genes related to ion exchange, play an important role in regulation.1D9152E6-FF06-4DC8-B029-2C5CAEBFEE6C

【研究的意義】海馬齒(Sesuvium portulacastrum)為番杏科(Aizoaceae)海馬齒屬(Sesuvium L.)多年生雙子葉鹽生植物,其作為紅樹林伴生植物,通常生長在世界各地沿海和內(nèi)陸的沙灘上(Yi et al.,2014;Chang et al.,2016),具有耐鹽霧、砂洗、貧瘠和耐高溫的特性(Rabhi et al.,2010a)。海馬齒屬于兩性生殖的鹽生植物,具有獨特的耐鹽特性,不僅能產(chǎn)生大量的生物量,可通過細胞和組織積累大量的Na+,可達872 mg/株,且在濃度高達800 mmol/L的NaCl溶液中正常生長,利用該特性可實現(xiàn)鹽漬土壤的改良(Rabhi et al.,2010b;Chang et al.,2016)。目前全球約20%的可耕地和7%的土地受到鹽漬化危害(Rizwan et al.,2015)。因此,海馬齒不僅對鹽堿地有修復(fù)功能,還能固定沙丘、修復(fù)污染海島和海岸帶生態(tài)環(huán)境(范偉等,2010;Lokhande et al.,2013;丁國華等,2020)。因此,開展在鹽脅迫下海馬齒根系的轉(zhuǎn)錄組測序分析,挖掘響應(yīng)鹽脅迫的功能基因,對探究海馬齒對鹽響應(yīng)的分子機制、改良農(nóng)作物耐鹽性及解決土壤鹽漬化具有重要的意義。【前人研究進展】鹽脅迫對海馬齒的影響研究主要集中在海馬齒的形態(tài)結(jié)構(gòu)基礎(chǔ)(Yi et al.,2014;Chang et al.,2016)、生理特性(Rabhi et al.,2010a;Kannan et al.,2013)及分子調(diào)控機制等方面(Ghnaya et al.,2013)。研究發(fā)現(xiàn),在鹽脅迫下,海馬齒葉片能保持足夠的氣體交換和色素組成(Rabhi et al.,2010b),且葉中參與離子結(jié)合、質(zhì)子轉(zhuǎn)運、光合作用和ATP合成的相關(guān)基因差異表達(Kannan et al.,2013;Yi et al.,2014)。目前耐鹽相關(guān)基因已有較多報道,如海馬齒的果糖-1,6-二磷酸醛縮酶基因(SpFBA)表達可提高海馬齒對鹽的耐受性(Fan et al.,2009)。甜菜的堿醛脫氫酶基因(SpBADH)表達產(chǎn)物可減少H2O2、增加脯氨酸和激活抗氧化酶,以改善活性氧(ROS)清除,提高植物對干旱或者滲透脅迫的耐受性(Yang et al.,2015)。水通道蛋白基因(SpAQP1)可通過增強植物的抗氧化性來提高其耐鹽性(Chang et al.,2016)。Na+/H+逆向轉(zhuǎn)運基因(SpNHX1)是響應(yīng)鹽脅迫的關(guān)鍵基因(Zhou et al.,2018)。鹽超敏感基因1(SpSOS1)和H+-ATP基因(SpAHA1)共表達可提高擬南芥的耐鹽性(Ji et al.,2013;Fan et al.,2019)。隨著測序技術(shù)的快速發(fā)展,高通量轉(zhuǎn)錄組測序已成為一種快速、高效的基因表達研究方法(Bazakos et al.,2015)。至今,已對大量植物的鹽敏感品種和耐鹽品種進行轉(zhuǎn)錄組測序分析的研究報道,例如Taji等(2004)利用比較基因組學(xué)研究擬南芥和鹽芥的耐鹽基因,結(jié)果發(fā)現(xiàn)鹽芥耐鹽的原因可能是Fe-SOD、P5CS、PDF1.2、AtNCED、P-protein、β-葡萄糖苷酶基因和SOS1基因共表達的結(jié)果;Rabello等(2008)從旱稻中鑒定出22種可能與耐旱相關(guān)的蛋白;Qiu等(2011)從楊樹中鑒定出與鹽脅迫相關(guān)的脫落酸(ABA)合成基因;且Sun等(2010)研究發(fā)現(xiàn),番茄耐鹽品種的SOS途徑更活躍,水楊酸結(jié)合蛋白2基因(SABP2)在其耐鹽機制中可能發(fā)揮重要調(diào)控作用;Zahaf等(2012)研究發(fā)現(xiàn),苜蓿bHLH轉(zhuǎn)錄因子可能在鹽脅迫中發(fā)揮重要作用;Ma等(2013)從鹽角草中鑒定出大量參與離子穩(wěn)態(tài)和滲透調(diào)節(jié)相關(guān)基因;Zhang等(2014)研究發(fā)現(xiàn),SnRK2、PYL、PP2C等差異表達基因與ABA的信號轉(zhuǎn)導(dǎo)途徑相關(guān);Bazakos等(2015)研究發(fā)現(xiàn),橄欖根系中有24個差異表達基因,其中9個上調(diào)基因,15個下調(diào)基因;在葉中有70個差異表達基因,其中14個下調(diào)基因,56個上調(diào)基因;Tian等(2018)研究發(fā)現(xiàn),SnRK2、ABF、HST、GSTs和GSH1基因在鹽脅迫中表現(xiàn)出高活性;Pan等(2019)研究發(fā)現(xiàn),Unigenes有15321個微衛(wèi)星標記基因,其中,有17個單核苷酸多肽(SNP)與6個鹽脅迫相關(guān)的差異表達基因(DEGs);Wang等(2020a)研究發(fā)現(xiàn),大穗結(jié)縷草中TaHSP23.9可能作為一種蛋白質(zhì)伴侶來正向調(diào)節(jié)植株對鹽脅迫的響應(yīng)。【本研究切入點】目前鮮見有關(guān)海馬齒根系響應(yīng)鹽脅迫轉(zhuǎn)錄組分析的研究報道。【擬解決的關(guān)鍵問題】利用Illumina測序技術(shù)對不同濃度NaCl脅迫處理的海馬齒根系進行轉(zhuǎn)錄組測序分析,并挖掘響應(yīng)鹽脅迫的功能基因,為培育耐鹽的農(nóng)作物新品種及有效解決土壤鹽漬化提供理論依據(jù)。1D9152E6-FF06-4DC8-B029-2C5CAEBFEE6C

2. 2 Unigenes功能注釋結(jié)果

將Unigenes在Nr、GO、Swiss-Prot、COG和KEGG五大數(shù)據(jù)庫中進行注釋,結(jié)果(表2)發(fā)現(xiàn),共有65535條Unigenes注釋成功,占Unigenes總數(shù)的52.36%,剩下的59638條Unigenes均未獲得注釋占Unigenes總數(shù)的47.64%。在Nr數(shù)據(jù)庫中被成功注釋的Unigenes最多,比對上的同源物種有擬南芥、水稻、蒺藜苜蓿、大麥、海金藻等。在GO數(shù)據(jù)庫中注釋成功的Unigenes如圖1所示。Unigenes被注釋為生物學(xué)過程和細胞組分兩大類別的數(shù)量較分子功能類別多。生物學(xué)過程類別中,富集程度最高的是細胞過程,其次是單一生物細胞過程和代謝過程;細胞組分類別中,富集程度較高的是細胞和細胞部分,其次是細胞器部分;分子功能類別中,富集程度最高的是催化活性和結(jié)合活性。

2. 5 差異表達基因的KEGG代謝通路富集分析結(jié)果

將獲得的24042個差異表達基因與KEGG數(shù)據(jù)庫進行比對,結(jié)果發(fā)現(xiàn)有10106個顯著差異基因富集到129條代謝通路,其中富集程度排名前10的代謝途徑為核糖體、次級代謝生物合成、RNA轉(zhuǎn)運、內(nèi)吞作用、剪接體、甘油磷脂代謝、內(nèi)質(zhì)網(wǎng)加工、吞噬、醚脂類代謝和植物—病原體相互作用(圖3)。由圖4可知,富集差異表達基因最多的通路為內(nèi)質(zhì)網(wǎng)加工蛋白通路,為948個基因,其中上調(diào)基因145個,下調(diào)基因803個,其次是吞噬體通路,為946個,其中上調(diào)基因120個,下調(diào)基因826個。此外,差異表達基因參與鹽脅迫密切相關(guān)的途徑包括硫代謝、脯氨酸積累、活性氧(ROS)代謝、與鹽脅迫相關(guān)的鈣信號通路和過氧化氫代謝(圖5)。在硫代謝中上調(diào)基因為SOS1和Na+/H+轉(zhuǎn)運蛋白基因(NHX1);脯氨酸累積中,proC基因上調(diào),而谷胱甘肽水解酶基因(GGT)和5-氧脯氨酸酶基因(OPLAH)下調(diào);ROS代謝中,脫氫抗壞血酸還原酶基因(DHAR)表達下調(diào),而過氧化物酶體膜蛋白基因2(Pxmp2)和線粒體內(nèi)膜蛋白基因17(Mpv17)基因表達上調(diào)。

3 討論

高度保守的熱激蛋白是一種組成型表達蛋白,并具有分子伴侶的功能,參與多種生物學(xué)過程,如轉(zhuǎn)錄、翻譯和翻譯后修飾、蛋白質(zhì)折疊及蛋白質(zhì)的聚集和解聚(Tiwari et al.,2015)。5個保守的Hsps家族(Hsp100、Hsp90、Hsp70、Hsp60和sHsp)和小熱休克蛋白(sHsp)在植物中普遍存在,在生物或非生物脅迫下其基因表達上調(diào),可作為分子伴侶保護其他蛋白免受非生物脅迫的破壞(Elizabeth et al.,2020)。本研究發(fā)現(xiàn),有7種以上的sHsps基因表達上調(diào),推測其參與耐鹽機制。前人研究發(fā)現(xiàn),TaHsp23.9、PfHsp17.2等sHsp基因的表達均提高了轉(zhuǎn)基因擬南芥的耐鹽性,推測sHsp保護了某些酶和蛋白質(zhì)在鹽脅迫下免于破壞和降解(Zhang et al.,2018;Wang et al.,2020b)。但Sun(2016)研究表明,轉(zhuǎn)基因擬南芥中AsHsp17基因表達降低植株對鹽的耐受性,其原因可能是不同種類sHsp對鹽脅迫的響應(yīng)機制不同。本研究還發(fā)現(xiàn),與ROS代謝相關(guān)的2個膜蛋白基因Pxmp2和Mpv17表達上調(diào),表明鹽脅迫下海馬齒根系的ROS合成代謝加強,其原因可能是鹽脅迫刺激下產(chǎn)生大量ROS(Mittler,2017),導(dǎo)致與ROS代謝相關(guān)基因表達上調(diào)。此外,ROS作為信號分子,將鹽脅迫信號傳遞給sHsp基因,從而導(dǎo)致sHsp基因表達上調(diào)(Wrzaczek et al.,2013)。鹽脅迫會引起蛋白質(zhì)錯誤折疊或未折疊蛋白質(zhì)的累積,使內(nèi)質(zhì)網(wǎng)中編碼分子伴侶基因及其他提高蛋白質(zhì)折疊能力基因的表達,有助于內(nèi)質(zhì)網(wǎng)恢復(fù)其穩(wěn)態(tài)(Walter and Ron,2011)。海馬齒在鹽脅迫下,差異表達基因中多種分子伴侶基因互作參與海馬齒的鹽脅迫響應(yīng),該結(jié)論在大穗結(jié)縷草(Zhang et al.,2018)亦得到證實。

在鹽脅迫下,海馬齒中參與到抗壞血酸-谷胱甘肽循環(huán)(AsA-GSH)代謝途徑中的脫氫抗壞血酸還原酶基因(DHAR)顯著下調(diào),與燕麥在鹽脅迫下的研究結(jié)果(劉建新等,2021)一致,但水稻DHAR在擬南芥中過表達可提高植株耐鹽能力(Ushimaru et al.,2006)。海馬齒的單脫氫抗壞血酸還原酶基因(MDHAR)和抗壞血酸過氧化物酶基因(APX)基因均顯著上調(diào)。該結(jié)論與鹽脅迫下大豆MDHAR基因表達受到抑制,但APX基因表達量升高的結(jié)論存在差異(Rahman et al.,2021)。此外,脯氨酸作為應(yīng)激反應(yīng)的銜接分子,在自然界中作用廣泛,在植物逆境脅迫的抗氧化反應(yīng)中發(fā)揮重要作用。脯氨酸處理過的煙草幼苗中APX和谷胱甘肽過氧化物酶(GPX)活性增強,說明脯氨酸參與提高煙草幼苗的抗氧化能力(Boudmyxay et al.,2019),推測脯氨酸在海馬齒鹽脅迫響應(yīng)中間接發(fā)揮作用。今后將通過轉(zhuǎn)基因技術(shù)進一步深入研究海馬齒中鹽脅迫響應(yīng)基因的分子調(diào)控機制。

4 結(jié)論

鹽脅迫下海馬齒差異表達基因如小分子量熱激蛋白基因、抗氧化酶相關(guān)基因及與離子交換相關(guān)基因發(fā)揮了重要調(diào)控作用。
