Abstract

The invention discloses application of an OsNPF5.11 gene to improvement in rice yield and belongs to the field of plant genetic engineering. An amino acid sequence of an OsNPF5.11 gene encoding protein is shown as SEQ ID NO.1, and a cDNA sequence is shown as SEQ ID NO.2. Through constructing a rice OsNPF5.11 gene overexpressing plant and an OsNPF5.11 gene interference plant, the increase in the normal number of tillers of rice and the number of grouting grains per plant through improving the expression of the OsNPF5.11 gene can be discovered; therefore, the OsNPF5.11 gene can be used in rice breeding to improve the rice yield. The OsNPF5.11 gene has an important application value in aspects of elaborating the influence of nitrogen elements on plant growth and development process and improving the rice plant type.

Description

technical field

[0001] The invention belongs to the field of plant genetic engineering, and specifically relates to OsNPF5.11 Application of genes in improving rice yield. Background technique

[0002] Plants obtain nitrogen by absorbing ammonia, nitrate, amino acids, soluble peptides, etc. in the soil; nitrogen absorption and transport mainly rely on ammonium transport protein (AMT), nitrate transport protein (NRT), amino acid transport protein (AAT) , Peptide Transporter (PTR) and other transport proteins (Williams L, Miller A. Transporters responsible for the uptake and partitioning of nitrogenous solutes. Annual Review of Plant Physiology and Plant Molecular Biology, 2001, 52: 659-688.). Ammonium is absorbed by plant AMT to synthesize glutamine and glutamate by glutamine synthase (GS) and glutamate synthase (GOGAT), which in turn form other amino acids (Sonoda Y, Ikeda A, Saiki S , et al. Feedback regulation of the ammonium transporter gene family AMT1 by glutamine in ...
