Abstract: Plant nitrogen use efficiency in corn has been improved by transformation with a flavohemoglobin gene. Plants comprising a flavohemoglobin gene have decreased nitric oxide (NO) levels, increased biomass accumulation under a sufficient nitrogen growth condition, and increased chlorophyll content under a limiting nitrogen growth condition. Additionally, these transformed plants evidence higher levels of yield.

Abstract: The present invention provides molecular constructs and methods for use thereof, including constructs including heterologous miRNA recognition sites, constructs for gene suppression including a gene suppression element embedded within an intron flanked on one or on both sides by non-protein-coding sequence, constructs containing engineered miRNA or miRNA precursors, and constructs for suppression of production of mature microRNA in a cell. Also provided are transgenic plant cells, plants, and seeds containing such constructs, and methods for their use. The invention further provides transgenic plant cells, plants, and seeds containing recombinant DNA for the ligand-controlled expression of a target sequence, which may be endogenous or exogenous. Also disclosed are novel miRNAs and miRNA precursors from crop plants including maize and soy.

Abstract: Disclosed herein are transgenic plants having recombinant DNA which expresses a G1073 transcription factor which provides enhanced resistance and/or tolerance to water deficit. More specifically the DNA constructs comprise a polynucleotide which encodes a at least a functional part of a G1073 transcription factor or a homologous transcription factor.
