Abstract

The invention discloses a paddy rice NRT 1.1A gene and an application of encoded protein of the paddy rice NRT 1.1A gene to improve the plant yield in breeding. Concretely, protein or an encoded genethereof is applied to regulate the growth and development of a plant. The growth and development is reflected as the single plant yield and / or the strain height and / or grain number and / or flowering time and / or bolting time and / or size of a rosette leaf. The protein is any one of (1) protein having the amino acid sequence shown as in the sequence 1 in a sequence list; and (2) protein which is derived from the sequence 1 by replacing and / or deleting and / or adding one or more amino acid residues in and / or from and / or to the amino acid sequence in the sequence 1 in a sequence list, and is relatedto control of the growth and development of a plant. The paddy rice NRT 1.1A gene and encoded protein are of great importance in breeding of new high-yield paddy rice variety.

Description

technical field

[0001] The invention belongs to the field of biotechnology, and relates to the application of a rice NRT1.1A gene and its coded protein in breeding for improving plant yield. Background technique

[0002] Plants need a variety of mineral nutrients to maintain their normal growth, and nitrogen is the mineral nutrient element that plants need the most. Generally speaking, nitrogen can account for 1.5-2% of the dry weight of the plant body. Nitrogen is a constituent of proteins, nucleic acids, phospholipids, and organic nitrogen compounds necessary for plant growth and development, and these substances are structural or functional components for living cells to survive, so nitrogen is also called a life element. In order to pursue the high yield of crops, a large amount of nitrogen fertilizer is often applied in agricultural production. Among them, the amount of nitrogen fertilizer applied to rice far exceeds that of any other crops, and the loss of nitrogen f...
