PAP1 gene for cultivating colored-leaf poplar and application of PAP1 gene

The invention provides a PAP1 gene for cultivating colored-leaf poplar and application of the PAP1 gene, and belongs to the technical field of plant genetic engineering. By overexpressing the PAP1 gene of the full red poplar (Zhonglin 2025 poplar bud variant) in the poplar, the leaf color of the poplar can be obviously changed, the leaf of the transgenic plant is red, and the red intensity of the tender leaf at the upper part of the plant is higher than that of the leaf at the lower part of the plant. Compared with a control plant, a large amount of pigments are accumulated in epidermal tissues of stems, leaves, veins and petioles of the PAP1 gene overexpressed plant. The invention finds that a new poplar germplasm material with obviously changed leaf color can be created by overexpressing the PAP1 gene of the full red poplar in the poplar, and a foundation is laid for cultivating a new variety of colored-leaf poplar. 本发明提供了一种培育彩叶杨树的PAP1基因及其应用，属于植物基因工程技术领域。本发明通过在杨树中过量表达全红杨(中林2025杨芽变体)PAP1基因，能够显著改变杨树的叶色，转基因植株叶
