本发明属于遗传工程技术领域,具体涉及一种NtHMA4突变体的制备方法与应用。
背景技术:
镉( Cd)、砷( As) 、铬( Cr) 、汞( Hg)和铅( Pb) 等是公认的对植物和人体危害比较大的重金属元素,植物必需微量元素锌( Zn) 、镍( Ni) 、铜( Cu)等如果过量也会产生危害。所以,关于作物重金属污染及其降低方法的研究越来越引起科研人员的重视。烟草(Nicotiana tabacum)是重要的经济作物,是茄科一年生草本植物。近年来关于烟草中重金属的研究也逐渐成为烟草减害研究的一个热点。
重金属对烟草品质会产生不利影响。烟碱含量是衡量烟叶品质的一个重要指标,在一定范围内提高烟碱有利于烟叶品质的提高,Cd 污染会降低烟叶烟碱含量,可能原因是根合成烟碱途径或者烟碱向上部转运过程受阻。另外,烟叶中可溶性糖对Cd、Pb极为敏感,轻度污染就会导致其含量明显下降,这可能是由于重金属破坏了烟草叶绿体,光合作用受阻引起的。重金属会导致烟叶糖碱比和氮碱比升高,化学成分组成失衡,品质受到影响。
重金属对人体的危害巨大,如过量的镉进入人体内可能对血管造成损害;另外镉元素对肠道吸收铁具有抑制作用,还会干扰钴、铜、锌等微量元素的代谢过程,引起肺、肾、肝等人体脏器损害,最终可能导致致癌、致畸和致突变等作用。砷可以诱发许多疾病,如急性砷中毒可造成中枢神经系统障碍导致全身麻木、呼吸道和消化道病变甚至快速死亡;慢性砷中毒导致神经系统紊乱、全身乏力、食欲减退、恶心以及皮肤色素沉着和角化病等皮肤病变等,而且可以引起肺癌、皮肤癌和膀胱癌等疾病。锌元素是人体的重要的微量元素之一,对人体的生长发育、智力、免疫功能甚至是视力都有至关重要的作用。但是人体中的锌不是越多越好。人体摄入过量的锌,在胃液中易转化成氯化锌,对胃黏膜有较强的腐蚀性,可致胃黏膜充血、水肿、甚至出血。过量的血锌会抑制白细胞的吞噬功能,是人体抵抗力下降,易受病菌感染。过量的锌还会影响人体其他无机盐的吸收与代谢,如影响铁的吸收,使肝脏中铁代谢受损成铜/锌比值过高;影响胆固醇代谢,形成高胆固醇血症等。镍及其盐类的毒性较低,但由于它本身具有生物化学活性,故能激活或抑制一系列的酶(精氨酸酶、羧化酶、酸性磷酸酶和拓脱羧酶)而发挥其毒性。镍可引起接触性皮炎。直接进入血液的镍盐毒性较高,胶体镍或氯化镍毒性较大,可引起中枢性循环和呼吸紊乱,使心肌、脑、肺和肾出现水肿、出血和变性。
烟草是我国重要的经济作物, 重金属污染不仅影响烟草本身生长发育,对吸食者的的健康也具有严重的威胁。减害一直是烟草科研工作的一个重要方向,其中降低重金属含量是一个重要的公关目标。
