Different genes are used to the research of phylesis because of their different evolutionary rate 不同基因由于其进化速率不同,而适用于不同分类等级的系统发育研究。
The evolutionary rate of ribosome dna is more fast and only suit to the phylesis between genus and species 核糖体dnaits序列进化速率更快,只能用于属间和种间分类群的研究。
Comparatively , the evolutionary rate of proteins coded by the nuclear genes is four or five times as fast as the rate of the two formers 与它们相比,核编码蛋白基因的进化速率分别快4 5倍和12 15倍。
Analysis of the variation of bases of epsps of brassicaceae , solanaceae and poaceae indicate that the evolutionary rates of epsps are different between brassicaceae and solanacea e and the rate in solanaceae is higher than the rate in brassicaceae according to the total substitution rate of bases 分别对十字花科、茄科、禾本科序列的碱基变异情况分析,结果表明, epsps基因在十字花科和茄科中的进化速率不一样,对于总的碱基替换率,茄科高于十字花科。
