摘要:
以裸子植物高山松为试验材料,利用笔者所在实验室前期构建的高山松miRNA数据,通过生物信息学方法筛选与高山松生长发育相关的miR171a,并通过基于RNA连接酶的cDNA末端快速扩增法(RLM-5′RACE)验证得出,GRAS家族转录因子(Unigene10015)和肌动蛋白结合蛋白(Unigene83401)的基因为高山松miR171a的靶基因。通过PCR技术克隆得到的高山松miR171a前体序列可形成茎环发夹结构,但其成熟序列的碱基保守性较差。系统进化分析显示,pde-miR171a与裸子植物火炬松的进化关系较近。经qRT-PCR分析发现,pde-miR171a在高山松茎中的相对表达量最高,其次是在针叶中,而靶基因Unigene10015在茎、针叶中的相对表达量较低,暗示pde-miR171a可以通过调控靶基因Unigene10015而参与高山松的生长发育。
