全球生态环境变化过程中松科物种的适应性进化机制研究

由于松科物种起源较早，使其经历了地球上主要的板块运动、海陆变迁和古气候变化等环境变迁事件。松科物种的适应性进化是应对环境变化的主要机制之一。针对当前林木研究中宏观生态环境信息和微观生物信息关联度小、综合信息利用低等问题，本项目拟以松科为研究对象，通过整合宏观生态环境变化、物种分布信息和微观生物信息，研究松科物种所经历的真实环境变迁，以及面对环境胁迫时微观基因的适应性进化机制。该项目将有助于我们理解全球环境变化时林木物种的响应机制，有助于我们应对当前全球变暖的生态危机。

Pinaceae has experienced major environmental changes such as plate movement, land and sea changes and paleoclimate changes due to its early origin. Adaptive evolution of tree is one of the main mechanisms to reply environmental changes. There is a problem that the correlation and utilization were invalid between Macro ecological environment and micro bioinformation in the study of forests. Take the pinaceae species as example, this project would integrate the micro-bioinformatics and macro-data of global ecological environment changes and forestry geographic distribution. We would study to restore the real ecological environment experienced by pinaceae, and elucidate the response pattern of forestry genes along with the changes of ecological environment. This project would help us to understand the mechanism of forest species when the global environment changes, and help us to deal with the ecological crisis of global warming.
