我们常说建树,那什么是系统发育树(phylogenetic tree)? A phylogenetic tree represents the evolutionary relationship among a set of organisms or groups of organisms, called taxa(singular: taxon) that are believed to have a common ancestor. 系统发育树是对认为有共同祖先的一组生物类群的分枝进化历史-祖先...
物种树：根据物种的分类关系而建立的树状结构。基因\蛋白树：根据DNA或蛋白质序列的相似性构建的树状结构。引导树不知道。进化树是根据进化关系构建的树状结构。系统发育树是根据进化、DNA或蛋白序列、分布等多种条件为依据构建的树状结构。
Tree of lifeOne of the most amazing aspects of evolutionary theory is that of common descent—that all life forms are actually related in a genetic and phylogenetic sense. In short, all life forms are "cousins" to a greater or lesser extent. This being the case, biologists strive to ...

研究分子进化所要构建的系统发育树(Phylogenetic tree),也叫分子树,对于一个未知的基因或蛋白质序列,可以利用系统发生树确定与其亲缘关系最近的物种。比如你得到了一个新发现的细菌的核糖体RNA,你可以将它跟所有已知的核糖体RNA放在一起,然后用他们构建一棵系统发生树。这样就可以从树上推测出谁和这个新细菌的关系最近...

程序使用perl getTree.pl即可显示帮助信息,perl getTree.pl 输入文件.fasta 输出文件名称,例如perl getTree.pl AP3.fasta ap3 输入原始多基因的fasta文件,会调用程序自动进行多序列比对,信息位点的筛选,核酸模型的选择,ML树的构建结果会生成以treefile结尾的树文件,可进一步利用figtree/Itol/ggtree进行可视化的操作。
The main part of this manuscript focuses on tree balance in phylogeny and population genetics. The binary tree structure is central in these fields. In phylogeny, trees represent the genealogies of species. In population genetics, trees represent the genealogies of genes and it is called the coale...
The brush and tree lizards (Urosaurus) are a small clade of phrynosomatid lizards native to western North America. Though not as well known as their diverse sister clade, the spiny lizards (Sceloporus), some Urosaurus have nonetheless become model organisms in integrative biology. In particular, ...
