依托长沙农业环境观测研究站不同施肥方式长期定位试验,直接从土壤中抽提总DNA和RNA,应用T-RFLP和RT-PCR技术在DNA和cDNA水平对比研究施肥对亚热带稻田土壤细菌丰度和群落结构的影响.结果表明,施肥和秸秆还田显著改变了土壤细菌群落组成(DNA水平)和转录组成(cDNA水平)结构,且不同处理中DNA水平的T-RFLP图谱与cDNA水平相差很大.施肥和秸秆还田降低了土壤中存在的细菌多样性,...
烟草突变体筛选与鉴定方法篇:6.烟草T-DNA激活标签突变体侧翼序列筛选与鉴定
烟草 突变体筛选 鉴定方法篇
2015/8/27
通过激活标签技术(activation tagging)得到突变群体是构建突变体库的一种重要方法,应用此种方法研究基因功能,不管是用正向或反向遗传学方法,都必须先获得插入位点的侧翼序列(flanking sequence)。随着拟南芥、水稻及烟草等作物的侧翼序列数据库的不断完善及烟草全基因组测序的完成,越来越体现出激活标签技术对于推动烟草功能基因组学研究具有巨大的潜力。
