Plant chloroplast development associated protein, and coding gene and use thereof

Abstract

The invention discloses a plant chloroplast-related protein and encoding gene and application thereof. The protein has one of the following amino acid residue sequences: 1) an SEQ ID No.1 amino acid residue sequence in a sequence table; and 2) the SEQ ID No.1 amino acid residue sequence in the sequence table is replaced by one or a plurality of amino acid residues and / or lost and / or added with a protein which is derived from SEQ ID No.1 and has relative development functions of plant chloroplast. When the encoding gene of a rice chloroplast development related protein is destroyed, the plant leaf albino can be caused; and the encoding gene can be applied to the work such as plant genetic improvement and the like, and is an important direction gene, for example, the encoding gene can be uses as a target gene for being applied in rice breeding material sterile lines and changing the color of leaves, and can also be used for two-line hybrid rice seed production or genetic breeding.

Description

technical field [0001] The invention relates to a plant chloroplast development-related protein and its coding gene and application. Background technique [0002] Leaf color mutants are ideal materials for studying a series of physiological metabolic processes such as plant photosynthesis, photomorphogenesis, hormone physiology, and plant growth and development. In addition, due to the complex regulatory signal interaction between the nucleus and chloroplasts during leaf development, cytoplasmic mutants are of great significance for revealing the regulatory mechanism of nuclear-cytoplasmic signals. In recent years, with the deepening of mutation mechanism research, the utilization value of leaf color mutants has received more and more attention. First of all, in crop hybrid breeding, leaf color can be used as a marker trait to identify the purity of hybrids, remove false hybrids in time, and ensure the purity of field hybrid rice. Secondly, leaf color mutants provide excel...
