Description

RS2Z32基因作为植物免疫负调控因子在提高作物抗性中的 应用
技术领域
本发明属于植物分子生物学与植物遗传工程领域，具体地说，本发明涉及剪切因子基因 RS2Z32作为植物免疫负调控因子在提高作物抗性中的应用。
背景技术
可变剪切是一种重要的转录后修饰过程，同一个基因mRNA的可变剪切可以产生多个 不同的转录本，可变剪切不仅可以增加转录的丰富性和蛋白的多样性，而且可变剪切过程中 产生的一些副产物也能参与基因的表达调控。随着转录组测序技术的快速发展，人们对可变 剪切的认识和理解也逐渐加深，在人类基因组中大约有95％的基因会发生可变剪切，在植物 基因组中会有60％-70％的基因会发生可变剪切。可变剪切是由剪切复合体来完成的，一般 认为剪切复合体包括5个核心的小核核糖核蛋白(snRNPs:U1,U2,U4,U5,U6)以及数百个 剪切辅助蛋白。最新研究结果发现，在拟南芥和水稻中分别有436个和362个辅助蛋白参与 其可变剪切过程，其中富含丝氨酸和精氨酸的SR蛋白以及富含甘氨酸的GRP蛋白是目前 植物中研究最为深入的剪切因子蛋白。
据报道，拟南芥中SR蛋白AtSR45可以负调控植物免疫；番茄中的SlSR30和SlSR45蛋白也可以在番茄与致病疫霉的互作过程中发挥重要作用；细菌P.syringae在拟南芥AtGRP7的T-DNA插入突变体上发病更加严重，这些结果表明剪切因子蛋白在植物响应外 界的生物胁迫过程中发挥着重要作用。番茄中的RS2Z32蛋白作为SR蛋白家族中的一员， 目前未见其在生物与非生物胁迫过程中的研究报道，并且RS2Z32的同源基因在马铃薯、烟 草、大豆、水稻、玉米和小麦、棉花等作物中也高度保守，因此研究RS2Z32基因在植物中 的抗性作用机制具有非常重要的理论价值与实际应用价值。
我国是一个农业大国，每年因各类病虫害引起的粮食损失高达数千万吨，严重威胁我国粮食生产安全和农业经济的可持续发展。长期以来人们一直使用化学农药对农作物病虫害进行防治，这不仅破坏了生态系统的平衡还威胁人类的健康生活。因此，利用基因编辑技术可以对植物中一些“不良基因”进行敲除从而达到去劣存优的目标，还能够明显缩短育种年限，因此在作物抗性改良上更为安全和快捷。目前，CRISPR/Cas9基因编辑技术已广泛运用到植物基因编辑过程中，利用该技术敲除植物內源的免疫负调控因子RS2Z32可以提高植物对不同病原菌的抗性。因此，研究并利用抗性关键基因RS2Z32对于植物抗病品种的改良具有非常重要的意义。

上游引物：SEQ ID NO.14

(1)农杆菌培养：利用TRV2的载体引物(SEQ ID NO.14和SEQ ID NO.15)对转入TRV2-RS2Z32质粒的农杆菌进行菌落PCR验证，挑取成功转入TRV2-RS2Z32载体的农杆 菌，并接种到含有液体LB(卡纳浓度50μg/mL，利福平浓度50μg/mL)的试管中进行培 养。在28℃，220rpm的摇床上培养12小时左右，然后将培养的农杆菌菌液收集在2mL的 离心管中，5000rpm离心3-4分钟收集农杆菌的菌体。随后用烟草注射缓冲液(10mM MgCl2,10mM MES,pH＝5.6,200μM AS)重悬菌体1-2次，利用分光光度计测定出菌液的 OD600浓度。用缓冲液稀释菌液，将TRV1和TRV2-RS2Z32(TRV1和TRV2-GFP作为阴性 对照)菌液按照1:1的比例等体积混匀，使得最终的浓度各为OD600＝0.5。
(2)沉默番茄的RS2Z32基因：选取刚刚长出2片子叶的番茄幼嫩小苗，将配好的农杆菌菌液注射到番茄叶片上，注射后将番茄置于温室中(24℃/14h光照和22℃/10h黑暗)继续培养。
(3)检测番茄中RS2Z32基因的沉默效率：选取生长4-6周的番茄叶片，随后将叶片放 入研钵中，并加入液氮进行研磨，反复研磨3-4次，再利用英俊公司RNA提取试剂盒(Catno.12183018A)，按照说明书中的操作流程提取番茄叶片的总RNA。随后用NanoDrop分 光光度计测定提取的RNA浓度，利用1μg RNA作为原始的模板，利用南京诺唯赞公司的 反转录试剂盒(R223-01)，按照试剂盒中的说明书进行操作获得cDNA。取适量的cDNA 作为qRT-PCR的模板，用于后续的沉默效率检测(图1)。
