Peanut ferrous transport protein as well as encoding gene and application thereof

Abstract

The invention relates to the field of plant molecular biology, in particular to a peanut ferrous transport protein gene as well as an encoding gene and application thereof. The invention discloses peanut ferrous transport protein AhNRAMP1 which is (1) a protein formed by an amino acid sequence shown as SEQ ID No.2, or (2) a protein formed by substituting, deleting or adding one or more amino acids in the amino acid sequence shown as SEQ ID No.2 and derived from (1), equal activity. The invention also discloses a gene for encoding the protein. The utilization efficiency on iron and the content of the iron in kernels can be improved by applying the new species of leguminous plants cultivated by the AhNRAMP1 provided by the invention.

Description

technical field

[0001] The invention relates to the field of plant molecular biology, in particular to a ferrous iron transport protein in peanut root system, its encoding gene and application. Background technique

[0002] The micronutrient iron is an essential element for the growth and development of various organisms. Iron deficiency in plants will seriously inhibit the growth and development of plants, resulting in a decline in yield and quality. Plants are the most fundamental food source for animals and humans. Therefore, it is of great significance to promote the absorption of iron in the environment by plants, the rational operation of plants and the accumulation of iron in grains to improve crop yield and quality and promote human health. Iron is the third limiting nutrient for plant growth, mainly due to the low solubility of iron in an aerobic environment (Yi et al., 1994). In fact, more than one-third of the soil in the world is deficient in iron. In order to a...
