Abstract:

Forestry is one of the important industries of the national economy. In-depth study of tree traits for the purpose of human needs and analysis of the molecular basis of the formation of tree important traits are the basic guarantee for the establishment of efficient breeding technology system， and the key to cultivate breakthrough varieties that meet the major national needs. This is of great significance to ensure the sustainable development of forestry in China， and serve major strategies such as national timber security， food security， ecological security and rural revitalization. With the rapid development of biotechnology， the research on the molecular basis of tree traits has become more in-depth. This paper focused on the formation and regulation mechanism of wood formation， forest economic traits and tree stress resistance， sorted out the current research progress at home and abroad， reviewed the molecular basis of tree trait formation， and prospected the future research trends and technological development of tree traits.

Key words: tree, traits formation, molecular basis, research progress

摘要：

林业是国民经济的重要产业之一，深入研究以人类需求为目的的林木重要性状，解析其形成的分子基础，是建立高效育种技术体系的基本保障，对培育满足国家重大需求的突破性良种，保障我国林业可持续发展，服务国家木材安全、粮食安全、生态安全和乡村振兴等重大战略具有重要意义。随着生物技术的快速发展，针对林木性状形成的分子基础研究也更加深入。综述了国内外林木性状形成的分子基础，聚焦木材形成、林木经济性状和林木抗逆性的形成与调控机制，对当前的研究进展进行了梳理，并对未来林木性状研究趋势与技术发展进行了展望。
