研究兴趣

研究兴趣是植物的物种形成、生物多样性对气候变化的生态响应和进化适应。主要应用现代群体遗传学(Population Genetics)、生物信息学和系统发育(Phylogenetics)的理论与方法对自然植物类群开展组学水平的进化生态学研究,分析遗传变异的结构和地理分布模式(Pattern),挖掘变异模式产生的遗传机制(Mechanism),模拟和揭示植物的物种形成过程(Process),探讨古气候变化/高山隆升对植物多样性的影响(Effects)。

 

Research Interests

Plant divergence, evolutionary adaptation and speciation, Ecological and evolutionary responses to climate changes. 

I mainly use the theory and methods of bioinformatics, population genetics and phylogenetics to study natural plants, 1) revel their population structure and geographically distributional pattern, 2) illustrate the underlying mechanisms and modeling the process of speciation, 3) discuss the effects of climate changes and alpine uplift on plant diversity.

 

主要发现
传统知识认为,同倍体生物间的杂交对生物的适应和多样化没有贡献。远交衰退是主要科学证据,如杂交后代结实率较低、杂交后代生存能力下降等。因而,长期以来,人们认为,同倍体生物间的杂交对物种演化没什么影响。如果杂交对进化没积极作用,那么生物应该在进化过程中尽力避免杂交发生,以节约有限资源。但是,我们在自然界中经常观察、观测到杂交现象。所以,杂交对生物适应和多样化,可能是有一些贡献的。以树木(如云杉属)为研究材料,利用DNA序列数据,我的研究工作发现,不同树木物种间基因交流并不罕见,物种间基因交流甚至可以帮助树木适应极端环境,物种间杂交也可以促进新物种的形成。这些结果表明,杂交能够在植物适应和多样化过程中发挥促进作用。
