摘要:
以含Ds元件的水稻稃片白化突变体为材料,采用TAIL-PCR技术分离Ds侧翼序列,并基于cDNA末端快速扩增技术(RACE)扩增Ds标记基因cDNA的3′端序列,分析突变体基因组上Ds插入引起的标记基因外显子改组现象。结果显示,水稻稃片白化突变体基因组含2个Ds拷贝,分别插入于1号和3号染色体上的类CBS结构域蛋白基因和推定的氧化还原酶基因的编码区;cDNA和基因组DNA经比对分析显示,Ds插入后,2个基因均导致基因的外显子改组,类CBS结构域蛋白基因和推定的氧化还原酶基因分别出现部分内含子序列和Ds序列的外显子化现象;Ds标记基因的编码区虽都出现了截短,但RACE扩增证实其在Ds插入后仍可表达出成熟的mRNA,这意味着Ds等转座元件介导的外显子改组,可能在基因组进化和蛋白质组多样化中发挥重要作用。
