Compositions and methods comprising promoters from the 4-hydroxyphenylpyruvate dioxygenase (HPPD) gene and active variants and fragments thereof, as well as chimeric promoters employing regulatory regions of the HPPD promoters are provided. Further provided are expression cassettes and plants comprising the various promoters disclosed herein operably linked to a polynucleotide of interest. Methods employing the various promoters described herein to modulate the expression of polynucleotides of interest are further provided.

Isolated polynucleotides and polypeptides and recombinant DNA constructs particularly useful for altering agronomic characteristics of plants under nitrogen limiting conditions, compositions (such as plants or seeds) comprising these recombinant DNA constructs, and methods utilizing these recombinant DNA constructs. The recombinant DNA construct comprises a polynucleotide operably linked to a promoter functional in a plant, wherein said polynucleotide encodes a SNF2 domain-containing polypeptide.

Methods and compositions are provided which employ a silencing element that, when ingested by a pest, such as a Coleopteran plant pest or a

This invention provides means for altering the harvest index of crop plants by modulating the expression of transgenic genes using dimerization domain and component stacks, thereby modulating plant architecture. The transgene/dimerization domain stacks are provided in a single transformation vector unit and are used to modulate plant growth, yield, and harvest index in plants.
