NUCLEIC ACID AGENTS FOR OVEREXPRESSING OR DOWNREGULATING RNA INTERFERENCE TARGETS AND USES OF SAME IN IMPROVING NITROGEN USE EFFICIENCY, ABIOTIC STRESS TOLERANCE, BIOMASS, VIGOR OR YIELD OF A PLANT

摘要

A method of improving nitrogen use efficiency, abiotic stress tolerance, biomass, vigor or yield of a plant is provided by expressing within the plant an exogenous polynucleotide encoding a polypeptide having an amino acid sequence at least 80 % homologous to SEQ ID NOs: 687-981, 992-1248, 1281-1310, 1389-1391, and 2806-3081. Also provided is a method of improving nitrogen use efficiency, abiotic stress tolerance, biomass, vigor or yield of a plan by expressing within the plant an exogenous polynucleotide which downregulates an activity or expression of a polypeptide having an amino acid sequence at least 80 % homologous to SEQ ID NOs: 311-514, 2007-2436, 1311-1320, 982-991, 1249-1280, 1321-1388. Transgenic plants and constructs are provided as well.
