Description
技术领域
本发明涉及作物生理技术领域,尤其涉及一种籽粒β-葡聚糖含量提高的转基因水稻的制备方法。
背景技术
β-葡聚糖是禾谷类植物籽粒细胞壁中的非淀粉多糖,是籽粒细胞壁的主要成分。β-葡聚糖属于膳食纤维成分之一,具有许多有益的健康特性,主要体现在以下几个方面:1.降低血糖血脂和血清胆固醇。β-葡聚糖能够减少小肠对脂肪及胆固醇的吸收率,从而降低血清胆固醇;同时β-葡聚糖作为一种粘性纤维,可通过影响肠道粘度而减缓碳水化合物的吸收,从而降低血糖;β-葡聚糖可降低血液中的胆固醇和葡萄糖浓度,从而降低心血管疾病和糖尿病的风险。2.改善肠道健康。β-葡聚糖在小肠中不能水解,而在大肠中降解并作为细菌发酵的底物,发酵产生乙酸、丙酸和丁酸等短链脂肪酸,抑制腐败菌,促进益生菌,维持肠道菌群平衡,从而促进肠道健康,其在胃肠道的正常运作和预防炎症以及结肠癌方面发挥着重要作用。总之,β-葡聚糖具有许多有益健康特性,其可能在改善健康和预防慢性非传染性疾病方面发挥关键作用,例如糖尿病、高胆固醇血症、肥胖症、心血管疾病和癌症等。
水稻是我国主要的粮食作物,随着我国经济的发展,国民对稻米的需求由吃得饱变为吃的健康,对高端稻米产业的功能稻供给研究逐渐提上日程。功能稻应具备优质的营养结构和丰富的营养供给,同时具有部分高端保健功能,对一些疾病的预防和防治都具有良好的效果。目前,生产上功能稻的主栽品种十分缺乏,选育进程缓慢,极大限制了人们日常饮食中对功能营养成分的摄取,限制了人们对高品质稻米的需求。已知水稻中β-葡聚糖含量极低,远远低于大麦和燕麦。
因此,提高水稻中β-葡聚糖含量可以提高人们日常饮食中对β-葡聚糖的摄取,通过食疗对糖尿病、高胆固醇血症、肥胖症和心血管疾病等有较好的辅助治疗功能;同时也为水稻功能营养品质育种提供材料基础,为功能稻的筛选和培育提供参考。
发明内容
本发明提供了一种籽粒β-葡聚糖含量提高的转基因水稻的制备方法,该方法能够使水稻籽粒中的β-葡聚糖含量提高至少3~4倍。
具体技术方案如下:
一种籽粒β-葡聚糖含量提高的转基因水稻的制备方法,包括:将GluB-1启动子和CslF6基因转入至受体植株中,得到转基因水稻;
将GluB-1启动子和CslF6基因进行重组,重组后的目标基因转入至受体植株中,得到转基因水稻;所述目标基因的核苷酸序列如SEQ ID NO.1所示。
进一步地,所述受体植株为水稻中花11或和华占。
进一步地,所述制备方法包括以下步骤:
(1)分别获取GluB-1启动子和CslF6基因;所述GluB-1启动子的核苷酸序列如SEQID NO.2所示,所述CslF6基因的核苷酸序列如SEQ ID NO.3所示;
(2)将步骤(1)的GluB-1启动子和CslF6基因连接至原始表达载体上,得到同时包含有GluB-1启动子和CslF6基因的重组表达载体;
(3)将重组表达载体转化至感受态细胞进行培养,得到基因工程菌;
(4)将步骤(3)的基因工程菌转化至受体植株内,得到转基因植株;
(5)验证步骤(4)的转基因植株,测定转基因植株籽粒中的β-葡聚糖含量,得到籽粒β-葡聚糖含量提高的转基因水稻。
进一步地,步骤(1)中,获取GluB-1启动子的方法为:
(A)提取水稻中花11幼苗叶片的基因组DNA;
(B)对基因组DNA进行一次PCR扩增,再对一次扩增后的产物进行二次PCR扩增,得到目标扩增产物;
所述一次PCR扩增所用引物如SEQ ID NO.6和SEQ ID NO.7所示;所述二次PCR扩增所用引物如SEQ ID NO.8和SEQ ID NO.9所示。
进一步地,步骤(1)中,获取CslF6基因的方法为:
(a)提取水稻叶片总RNA,反转录成单链cDNA;
(b)以单链cDNA为模板,进行第一轮PCR扩增,再对第一轮PCR扩增后的产物进行第二轮PCR扩增,得到目标扩增产物;
所述第一轮PCR扩增所用引物如SEQ ID NO.10和SEQ ID NO.11所示;所述第一轮PCR扩增所用引物如SEQ ID NO.12和SEQ ID NO.13所示。
进一步地,所述原始表达载体为B24_pCAMBIA-1300-35S-GFP-Nos。
进一步地,所述感受态细胞为大肠杆菌DH5α。
与现有技术相比,本发明具有以下有益效果:
本发明将GluB-1启动子和CslF6基因进行重组,重组后的目标基因转入至受体植株中,获得的转基因水稻能够显著提高水稻籽粒中的β-葡聚糖含量,在水稻遗传育种领域可用于培育高β-葡聚糖含量的水稻新品种,为功能稻的筛选和培育提供理论指导。

实施例4功能验证
对上述实施例1~3中的转基因阳性植株与对照组植株CK(非转基因植株)成熟籽粒进行β-葡聚糖含量的测定分析,测定采用Megazyme试剂盒。结果发现,与对照相比,仅实施例1中导入SEQ ID No.1(GluB-1启动子连接CslF6基因组合)的转基因阳性植株籽粒β-葡聚糖含量极显著升高,最高可分别达对照的350%(中花11)和500%(华占)左右,而实施例2和3(其他启动子和基因组合)在两个受体材料中均不能提高水稻籽粒β-葡聚糖含量。因此,通过以上分析发现通过在水稻中外源导入SEQ ID No.1序列可提高水稻籽粒β-葡聚糖含量。
