叶脉网络系统的构建和系统学意义研究进展

Advances on Construction of Leaf Venation System and Its Significance of Phylogeny

摘要:

为了解国内外叶脉网络系统的研究状况,综述了基因、激素对叶脉网络系统发育的调控机理,并剖析了叶脉的功能和系统学意义,分析了光、温度、水和外力破坏等环境因子对叶脉密度、叶脉直径等结构性状的影响.同时,综合考量植物碳投入经济权衡,阐明了叶脉网络系统是在遗传控制基础上由环境与碳投入共同调控建成.最后,对植物叶脉网络系统研究中存在的问题与未来发展方向进行了展望.

Abstract:

In order to understand the research status of leaf venation system, the regulation mechanisms of leaf venation development by genes and hormones were reviewed, and the function of leaf venation and its significance were analyzed. The effects of environment factors, such as light, temperature, water, on the structure characters (density, diameter of leaf venation) was also analyzed. Meantime, comprehensive consideration of plant carbon into economic trade-offs, it was clarified that leaf venation system was constructed co-regulated by environment and carbon input based on genetic control. At last, the problems and future direction in studying of leaf venation system were prospected.
