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

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.
