Problems solved by technology

However, the synthesis of chlorophyll is regulated by internal and environmental factors, and this regulation is controlled by nuclear genes and (or) plastid genes. Therefore, there is a complex regulatory network for the synthesis and degradation of chlorophyll.

Abstract

The invention discloses a method for changing the content of chlorophyll in a plant. The method comprises the following step of making the FHY3 protein encoding gene of a starting plant to lose function to obtain a target plant, wherein the content of chlorophyll in the target plant is lower than that of the starting plant and / or photochemical efficiency of a photosystem II of the target plant is lower than that of the starting plant. According to the invention, a transgenic plant is obtained by using RNAi (ribonucleic acid interference) to inhibit the FHY3 gene. The content of chlorophyll in leaves of the transgenic plant is lowered, thus the color of the leaves is light and the photochemical efficiency of photosynthesis is lowered. The method disclosed by the invention has a broad application prospect in the field of plant genetic breeding.

Description

technical field [0001] The present invention relates to a method for changing the chlorophyll content in plants. Background technique [0002] Photosynthesis is the process of using solar energy on the largest scale on earth, which provides organic matter, energy and oxygen for almost all life activities. About 220 billion tons of organic matter are synthesized through photosynthesis on the earth every year, which is equivalent to 10 times the annual energy consumption required by human beings. 90%-95% of plant dry matter comes from the products of photosynthesis, and photosynthesis is the material basis for crop yield formation. Photosynthesis is mainly carried out in the chloroplast of plant leaves, which requires the participation of a series of pigments and protein complexes. Chlorophyll is the main pigment that absorbs light energy. The reduction or absence of chlorophyll will make the color of leaves lighter and directly affect the efficiency and function of photosyn...
