摘要:谷氨酸脱氢酶(glutamate dehydrogenase, GDH)在植物体内催化合成谷氨酸的可逆反应,通过GDH固氮比谷氨酸合成酶途径更节省能量。在植物大多数组织中,GDH1是该基因家族中表达最高的基因,比其他GDH成员具有更为重要的作用。本研究从普通小麦基因组中分离了TaGDH1基因在A、B、D染色体组的序列。针对TaGDH1a基因在基因组DNA序列1 900~1 983 bp位置存在的核苷酸差异设计了一个插入/缺失标记,同时将该标记定位在5A染色体上。

3讨论

普通小麦为异源六倍体(2n=6x=42),具有六个染色体组,在二倍体物种中为单拷贝的基因在普通小麦中可能有3个拷贝,分别由A、B和D三个亚基因组编码,因此区分基因所在的染色体组比较困难[20]。郝丽芳等[21]在对小麦NOA基因所属染色体组区分时,设计两对保守的跨内含子的引物,通过基因组PCR、克隆和测序后的序列多态性分析,确定了小麦基因组中至少存在3个NOA成员,结合基于毛细管电泳的片段分析将3个成员定位在6A、6B和6D染色体上。李亚青[22]等以中国春缺体-四体系为材料,用Southern杂交的方法将TaGSK1基因定位于第一同源群的1A、1B和1D染色体。张磊等[23]利用特异引物在中国春缺体-四体中扩增产物的长度差异,将TaCKX5基因定位在小麦的3A、3B和3D染色体上。本研究利用二倍体、四倍体中各染色体组与六倍体小麦中的相对应染色体组基因相似度高的特点,将通过基因克隆获得的二倍体、四倍体GDH1基因与六倍体小麦中的TaGDH1基因序列进行对比,以区分三条TaGDH1基因所属的染色体组。同时结合中国春缺体-四体染色体定位和RIL群体连锁分析的方法将TaGDH1a-InDel标记定位在5A染色体上。

Andersen等[24]首先提出基因功能标记概念,功能标记的多态性来源于造成等位基因功能差异的DNA序列差异,可以进行基因型鉴定和基因型选择。因此,开发功能标记对于提高小麦育种效率具有重要意义。本研究中TaGDH1a基因功能标记的开发有助于GDH1在小麦中功能的研究以及TaGDH1基因型的鉴别。碳、氮代谢直接影响作物经济产量。已有研究表明,小麦中大部分与驯化和产量形成有关的QTL位点都聚集在第一和第五同源群染色体上[25, 26]。其中5A染色体上已发现存在控制穗长、穗粒数、穗粒重等小麦产量性状的主效QTL位点区域[27, 28]。本研究通过中国春缺体-四体系统,结合连锁分析的方法,成功将TaGDH1a基因定位到了小麦5A染色体上,为今后结合5A上已知产量性状相关QTL研究TaGDH1基因功能奠定了基础。
