青藏高原区杨属的系统发生及对分类和育种的启示
Phylogeny of Populus in the Tibetan Plateau and Its Implications for Classification and Breeding
分类学是人类认识、研究和利用生物的基础。杨属是世界上分类最困难的生物类群之一。杨属的分类在国内外一直都存在很大的分歧,这对杨树的科学研究、品种选育和栽培利用都带来不利影响。杨属分类的最终目标是建立基于系统发生的统一分类系统。经过 18 年的大量的系统学野外调查,我们在青藏高原区找到了青杨组和大叶杨组的有种群分布的 30 个分类群,其中 8 个是首次发现的新分类群。通过整合形态学、基因组生物信息学、生态学、生物地理学和育种学等多学科的研究,我们证明…查看全部>>
Taxonomy is the basis of recognizing,studying and employing living beings.The genus of Populus is considered as one of most difficult biotic group for classification in the world.There are a great divergence and many arguments in its taxonomy,which brings unbeneficial effects on research,breeding and cultivation of poplar.To establish a unified classification system based on phylogeny is ultimate goal for Populus classification.In an 18-year-long investigati…查看全部>>
