Abstract: Disclosed in the present invention is a synthetic glyphosate-resistant gene and the use thereof. the gene provided in the present invention in one of following (a)-(c): (a) a DNA molecule having a nucleotide sequence shown as sequence 2 the sequence listing; (b) a DNA molecule having nucleotide sequence shown as positions 1-1335 of sequence 2 in the sequence listing; (c) a DNA molecule having a nucleotide sequence having an identity of at least 98% with the sequence 2 or the position 1-1335 of the sequence 2 in the sequence listing and encoding a protein shown as sequence 9. Experiment demonstrates that the transgenic maize with the synthetic glyphosate-resistant gene provided by the present invention has significantly increased G2-aroA protein expression and significantly improved tolerance to glyphosate compared with the transgenic maize with the prokaryote glyphosate-resistant gene G2-aroA.

Abstract: This invention provides isolated polynucleotides, polypeptides, and recombinant DNA constructs useful for conferring an alteration in one or more plant architecture characteristics. Also provided are methods utilizing these polynucleotides, polypeptides, and recombinant DNA constructs. In certain embodiments, the recombinant DNA construct comprises a polynucleotide operably linked to a promoter that is functional in a plant, wherein said polynucleotide encodes a Squatty-Crinkle-Leaf Polypeptide.
