Research Progress of Leaf Color Variation Mechanism in Woody Plants
Colorful woody plants have bright foliage,high ornamental value,and are valuable to the garden landscape.In recent years,more and more attention has been paid to the configuration of colored woody plants in landscape design.The most direct cause of leaf color change is the alteration in pigment content and ratio in the leaves.Leaf color variation is influenced by both genetic and environmental factors.Leaf color can be regulated through controlling light,temperature and other factors.With the development of molecular biology,several key genes for regulating leaf color variation have been discovered in woody plants.Here,we summarize the progress of researches related to leaf color variation in woody plants,including studies on environmental factors,leaf microstructure,and molecular mechanism of leaf color variation and related genes,so as to provide a theoretical basis for further improving our understanding on the mechanism of leaf color variation in woody plants and cultivating additional ornamental colored woody trees.
