Phosphorus deficiency response regulatory protein and coding gene and application thereof

Abstract

The invention discloses a phosphorus deficiency response regulatory protein and a coding gene and application thereof. The protein provided by the invention is protein (a) or protein (b), wherein the protein (a) has amino acid sequences shown as a sequence 1 in a sequence table; and the protein (b) has an amino acid sequence which is derived from the sequence 1 by substituting and / or losing and / or adding one or more amino acid residues and is related with the phosphorus absorption of plants. By transforming the coding gene of the protein into the plants, the phosphorus absorbed by the transgenic plants is increased, so the phosphorus content of the transgenic plants is greatly increased, the phosphorus nutrition condition is improved, and both the plant height and the root length of the plants are obviously increased. Under the condition of same soil fertility, particularly low phosphorous, the transgenic plants can require less fertilizer application, so soil environmental pollution is reduced and resources are saved. The regulatory protein plays an important role in improving breeds of plants, particularly food crops and commercial crops such as wheat, rice, cotton and the like, and has a broad prospect.

Description

technical field [0001] The invention relates to a phosphorous deficiency response regulating protein, its coding gene and application. Background technique [0002] Phosphorus is one of the macronutrients necessary for plant growth. It is not only an important component of ATP, nucleotides and phospholipids in plant cells, but also plays a very important role in regulating energy transfer, protein activation and carbon and nitrogen metabolism. . The absolute phosphorus content in soil is usually very high (>1000μM), but phosphorus is easily fixed in organic and inorganic forms in soil, so the concentration of available phosphorus is very low, about 2-10μM, less diffused to the root surface, very Difficult to meet the needs of plant growth and development. In agricultural production, the main way to solve the problem of soil phosphorus deficiency is to apply a large amount of phosphorus fertilizer to the soil to meet the needs of plant growth, but this will not only incr...

AI Technical Summary

Problems solved by technology

The absolute phosphorus content in the soil is usually high (>1000μM), but phosphorus is easily fixed in the soil in organic and inorganic forms, so the concentration of available phosphorus is very low, about 2-10μM, less diffused to the root surface, very Difficult to meet the needs of plant growth and development

In agricultural production, the main way to solve the problem of soil phosphorus deficiency is to apply a large amount of phosphorus fertilizer to the soil to meet the needs of plant growth, but this will not only increase the cost of agricultural products, but also cause damage to the geological environment
