Yellow-throated marten\'s relationship is between Stone marten and Fisher marten.Fisher marten is the first species who was divided from Martes.The second one were Yellow-throated marten and Stone marten.Based on the analysis of the fossil note,Martes came from Central Europe,Fisher marten,Yellow-throated marten and Stone marten belonged to a branch which evolved to temperate zone.Boreal forest martens was another branch which evolved to cold environment.It is suggested that Yellow-throated marten and Fisher martenwere ascertained genus separately.4、By contrasting and analyzing 11 complete mitochondrial control region gene sequences of Mustelidae,the extended termination associated sequence domain、the central domain and the conserved sequence block domain were identified.A extended termination associated sequence(ETAS1) and eight conserved sequence(CSB-F、E、D、C、B、1、2、3) was indicated,and sequence mode was presented.Different kind of short repeat sequences were found between CSB1 and CSB2.With wolf as the outgroup,the phylogenetic evolution relationship of Mustelidae was analyzed using the neighbor-joining method.

而基于鼬亚科动物线粒体DNA12种重链编码蛋白基因序列及石貂和渔貂线粒体ND2和cyt b全序列，以狼、狗獾和水獭为外类群，应用NJ、MP和ML法构分别构建貂属和貂熊的系统进化树，结果表明：紫貂与日本貂亲缘关系较美洲貂近，石貂与真貂亚属亲缘关系较近，黄喉貂介于石貂和渔貂之间；渔貂是最早从貂属分化出的种类，其次是黄喉貂和石貂；结合化石记录分析，貂属起源于中欧地区，渔貂、黄喉貂和石貂属于一个向温带进化的分支，而真貂亚属为另外一个向寒冷环境进化的分支，建议将黄喉貂和渔貂分别定为单独的属。4、比对并分析11种鼬科动物线粒体DNA控制区序列，识别出延长终止序列区、中央区和保守序列区3个区域，指出了一个终止相关序列ETAS1及8个保守序列(CSB-F、E、D、C、B、1、2和3)，并给出了序列通式，在CSB1和CSB2之间发现具有不同形式的短串联重复序列。

Molecular phylogenetic analysis showed that the genus Cordyceps was not a natural group, only Neocordyceps of three subgenera of Cordyceps formed a monophyly.

分子系统学分析结果表明，传统形态分类所依据的特征在某种程度上不能反应虫草属的自然进化关系。

With the 39 species nrDNA ITS sequence from Genbank and by using nrDNA ITS sequence information of our study 31 species, a phylogenetic analysis was carried out on 70 species of Paphiopedilum, and then the results have been analyzed with the results from RAPD molecular marker of 30 species, indicated that, we supported Kirasawa's system proposed in 1982 on Paphiopedilum that this genus can be divided into six subgenera.

基于 ITS 序列的数据对兜兰属70个种的研究，结合 RAPD 对于中国兜兰30个种的研究结果进行分析，支持唐沢耕司（1982）所提出的将兜兰属分为6个亚属的观点，其中产于中国的兜兰属植物可以划分为5个亚属；认为巧花兜兰不能并入海伦兜兰中，最多可以作为其变种处理，或者独立成种，隶属于兜兰亚属的 Paphiopedilum 兜兰组；不支持将文山兜兰并入巨瓣兜兰或者同色兜兰中，可以作为是其变种处理，隶属于 Concoloria 组。

The phylogenetic analyses suggested that the YLS of BPH with different virulence belonged to the subphylum Ascornycotina, the class Pyrenomycetes, and had the closest genetic relationship with Hypomyces chrysospermus.

结果显示，褐飞虱3种不同致害性种群体内的YLS同属子囊菌亚门的核菌纲，并与此纲中的Hypomyces chrysospermus亲缘关系相对最近。
