- W906346050 abstract "测定了南海球形棕囊藻香港株P1、P2和湛江株ZhJ1的rDNAITS区序列（含5.8srDNA）,结合GenBank的13条同源序列,比对长度为904bp,变异位点271个,简约信息位点221个,平均（A＋T）（34.5%）〈（G＋C）（65.4%）.藻株P1、P2和ZhJ1序列存在变异位点20个,序列间相似性为97.9%～98.5%.ITS序列在种间和种内的解析度高于18srDNA和28srDNA基因;构建的NJ树、MP树、贝叶斯推断系统树的结构是一致的,不同种类的棕囊藻单独聚类,不同地理来源的球形棕囊藻混杂分布但相同地理来源的藻株多聚类在一起.RNA二级结构显示,不同藻种间5.8srDNA区结构基本一致,表现出属的特异性;ITS1、2区结构表现较大的种间差异,表明ITS区RNA二级结构可为棕囊藻分类鉴定提供有用的分子结构信息." @default.
