近年来,全球气候变暖,降雨量减少以及不适当的灌溉,导致干旱以及半干旱地区土壤盐渍化愈加严重,土壤盐渍化成为全球农业生产中面临的重大难题[1-2]。目前,中国可耕地面积中约1/5的盐渍化土地,总面积高达0.98亿hm2[2]。中国是世界人口大国,人均耕地面积不足0.1 hm2,如何利用盐渍化的土地,促进粮食产量的增加是艰巨的课题[3],因此,研究植物的耐盐性和生理机制,筛选及培育耐盐作物品种成为农业研究领域的热点之一。
在长期的进化过程中,植物进化出多种应对盐胁迫的防御机制,其中报道较多的主要有4种:①渗透调节平衡机制。分为有机渗透调节和无机渗透调节。无机渗透调节是植物细胞通过吸收钠离子(Na+)和钾离子(K+)等无机离子作为渗透调节剂,将Na+在细胞内区隔化,从而使根和地上部积累较多的Na+,但不会出现明显的毒害症状[4-6]。有机渗透调节则是指植物通过自身合成并积累一些可溶性无毒的有机小分子物质,如糖类、氨基酸类和甜菜碱等来维持细胞渗透平衡[7-8]。如盐胁迫下,苹果Malus pumila通过积累可溶性有机溶质和无机盐离子来降低胞内渗透势[9-10],番茄Lycopersicon esculentum叶片中可溶性糖含量升高[11]。②离子的区域化与pH调节机制。植物细胞利用跨膜运输将Na+和K+等无机离子转运至液泡中,使之与细胞质隔绝,降低渗透势,避免细胞器遭受毒害[12]。同时,植物自身可以分泌有机酸从而调节根细胞中的pH稳态,缓解盐胁迫对根系的毒害[13]。③抗氧化防御系统机制。在高盐胁迫下,植物细胞质膜因受到水分胁迫或者离子胁迫而受损,从而导致脂质过氧化,使细胞内积累大量的活性氧,当积累的活性氧超过了细胞自身的清除能力就会对细胞造成损伤[8, 14-15]。在长期的进化过程中,植物自身会产生活性氧清除系统,包括一些抗氧化酶类等抗氧化物质,如超氧化物歧化酶(SOD)、过氧化物酶(POD)、过氧化氢酶(CAT)、谷胱甘肽过氧化物酶(GPX)等,它们是衡量植物抗逆性的重要指标[6,16-17]。④内源激素和信号转导途径。研究发现植物内源激素在盐胁迫反应中起着重要作用,如脱落酸(ABA)、乙烯(ET)、茉莉酸(JA)等[18-20]。同时,蛋白激酶途径、ABA途径(ABA依赖型、ABA不依赖型)、盐超敏感(SOS)途径等[21-24]信号转导途径也参与了植物对盐胁迫的响应,并在其中发挥重要作用。
植物激素信号调控网络是植物应对各种非生物胁迫所必须的[25]。茉莉酸(jasmonic acid,JA)作为重要的植物逆境激素在调控植物耐盐性方面发挥着重要的作用。耐盐水稻Oryza sativa品种内源茉莉酸含量高于盐敏感品种,外源茉莉酸甲酯处理能够提高水稻幼苗耐盐性和大豆Glycine max幼苗对盐胁迫的抗性[26-27]。盐胁迫下,水稻JA信号调控基因OsJAZ9与OsbHLH062互作介导离子稳态或通过增强抗氧化能力,从而增加对盐胁迫的耐受性[28-29];内源茉莉酸通过维持番茄体内活性氧稳态来提高番茄的耐盐性[30]。但是,目前关于JA信号如何调控植物的耐盐性仍鲜有报道。茉莉酰氨基酸结合物合成酶(jasmonoyl amino acid conjugate synthase,JAR1)催化JA形成JA-Ile,AtJAR1基因发生突变后可导致JA信号传递中断。因此,本研究运用CRISPR/Cas9基因编辑技术创建拟南芥Arabidopsis thaliana AtJAR1基因突变体,并考察突变体对盐和ABA胁迫下的种子萌发和根系生长影响,以及盐胁迫下突变体对K+的吸收转运和AtHAK5表达量的影响,从而解析JA信号通路在植物耐盐性中的可能生理机制。

摘要:
目的 茉莉酰氨基酸结合物合成酶(jasmonoyl amino acid conjugate synthase,JAR1)可以催化茉莉酸(jasmonic acid,JA)形成茉莉酸的活性形式茉莉酸异亮氨基酸复合体(jasmonic acid-isoleucine,JA-Ile),从而激活JA信号途径。JA信号途径在介导植物盐胁迫的响应中发挥重要作用,因此,探究AtJAR1在植物耐盐性中的功能对于研究JA信号途径影响植物耐盐性的机制具有重要作用。 方法 运用CRISPR/Cas9基因编辑技术,创建了2个不同的拟南芥Arabidopsis thaliana AtJAR1基因突变体,并对这2个突变体进行地上部生物量的统计分析和JA信号标记基因的表达分析,以确定AtJAR1基因功能缺失。之后,观察分析不同浓度氯化钠和脱落酸(ABA)处理对jar1突变体的种子萌发和幼苗建成的影响,明确AtJAR1基因对拟南芥耐盐性的影响。最后,通过比较分析盐处理前后野生型和突变体的钾离子(K+)和钠离子(Na+)质量摩尔浓度,以及高亲和力K+转运蛋白基因AtHAK5的表达变化情况,初步探究AtJAR1基因在拟南芥耐盐性中的功能。 结果 JA信号标记基因AtVSP1和AtVSP2的表达量大幅下调,表明AtJAR1基因功能丧失。与点突变产生的jar1-1突变体不同的是,这2个突变体表现为前3周生长加快,之后逐渐减缓并出现叶片萎蔫的表型。同时,AtJAR1突变可以缓解盐胁迫和ABA对种子萌发和根系生长产生的抑制作用。此外,盐胁迫下AtJAR1突变可以促进AtHAK5的表达和根系对K+的吸收转运。 结论 JA信号途径可能通过与ABA交互作用影响AtHAK5的表达量,以调节植物根系对K+的吸收转运,进而改变细胞内K+/Na+平衡,最终影响植物耐盐性。图8表2参52 -

Abstract:Objective Jasmonal amino acid conjugate synthase (JAR1) can catalyze jasmonic acid (JA) to form jasmonic acid-soleucine (JA-Ile), an active form of jasmonic acid, and activate the JA signal pathway. JA signaling pathway plays an important role in mediating the response of plants to salt stress. This study aims to explore the function of AtJAR1 in plant salt tolerance, which plays an important role in studying the mechanism of JA signal pathway affecting plant salt tolerance. Method CRISPR/cas9 gene editing technology was used to create two different Arabidopsis thaliana AtJAR1 gene mutants. The aboveground biomass of the two mutants and the expression of JA signal marker gene were analyzed to determine the loss of AtJAR1 gene function. Then, the effects of different concentrations of NaCl and ABA treatment on seed germination and seedling establishment of jar1 mutants were observed and analyzed to clarify the effect of AtJAR1 gene on salt tolerance of A. thaliana. Finally, the role of AtJAR1 gene in salt tolerance of A. thaliana was investigated by comparing the content of potassium and sodium ions in wild type and mutants before and after salt treatment, as well as the expression of AtHAK5, a high affinity potassium ion transporter gene. Result The expression of JA signal marker genes AtVSP1 and AtVSP2 decreased significantly, indicating the loss of AtJAR1 gene function. Different from the jar1-1 mutant produced by point mutation, the growth of the two mutants accelerated in the first three weeks, then gradually slowed down and the leaves wilted. At the same time, AtJAR1 mutation can alleviate the inhibition of salt stress and ABA on seed germination and root growth. In addition, AtJAR1 mutation can promote the expression of AtHAK5 and the absorption and transport of potassium ions in roots under salt stress. Conclusion JA signaling pathway may affect the expression of AtHAK5 through interaction with ABA, so as to regulate the absorption and transport of K+ by plant roots, change the intracellular K+/Na+ balance, and finally affect plant salt tolerance.
