Hunong 5 has high commercial value due to its high polysaccharide and triterpene content, This is the first report of using a DNA pooling method to develop a stable sequence characterized amplified region （SCAR） marker for rapid identification of the G. lucidum Hunong 5 cultivar. The SCAR marker was developed by first generating and sequencing a distinctive inter simple sequence repeat （ISSR） fragment （882 bp） from G. lucidum Hunong 5 cultivar. A stable SCAR primer pair GLH5F/GLH5R were obtained to identify the cultivar and the SCAR marker is a DNA fragment of 773 bp.展开更多

The results showed that two SNPs were found at position 209 （T/C） and position 533 （C/A） of the 10^th exon of GHR gene in the two mink populations.展开更多
为了快速筛查Toll样受体2基因的SNPs,采用DNA池和直接测序法确定了荷斯坦牛TLR2基因的多个SNP突变方式,估算了各SNP的等位基因频率,并利用生物信息学方法预测突变对TLR2 m RNA和蛋白的影响。结果显示,在荷斯坦牛TLR2基因内共发现6个核...为了快速筛查Toll样受体2基因的SNPs,采用DNA池和直接测序法确定了荷斯坦牛TLR2基因的多个SNP突变方式,估算了各SNP的等位基因频率,并利用生物信息学方法预测突变对TLR2 m RNA和蛋白的影响。结果显示,在荷斯坦牛TLR2基因内共发现6个核苷酸突变位点,分别为T602A、G10900C、G11047C、A11076T、C12077T、T10634G,其中T10634G为错义突变,导致第64位氨基酸由原来的谷氨酸(Gly)替换为天冬氨酸(Asp)。研究结果可为中国荷斯坦牛的抗病育种提供实验依据。展开更多
