Abstract: A plant with modified flower morphology is produced by suppressing a function of a transcription factor involved in determining the polarity of plants. More particularly, a plant with modified flower morphology is produced by the steps of obtaining a transformed cell by introducing a chimeric DNA in which a DNA encoding a transcription factor involved in determining the polarity and a functional peptide converting a transcription factor into a transcription repressor are fused; and regenerating a transformed plant from the transformed cell.

Abstract: A DNA encoding a phosphinothricin acetyltransferase protein obtained from Streptomyces sp. AB3534 strain is described which imparts a resistance to herbicides, particularly the herbicide phosphinothricin (PPT). Plants having a herbicide resistance are constructed by transforming a plant cell with DNA encoding the phosphinothricin acetyltransferase protein and then regenerating the transformed plant cell into a plant. A recombinant protein having the herbicide-resistant activity is also described.

Abstract: To provide a novel herbicide-resistance gene and a plant imparted a resistance to herbicides by using this gene, a plant having a resistance to herbicides is constructed by transforming a plant cell by a DNA encoding the following protein (A) or (B) and then regenerating the thus transformed plant cell in a plant. (A) A protein having the amino acid sequence represented by SEQ ID NO:2. (B) A protein having an amino acid sequence of SEQ ID NO:2 including substitution, deletion, insertion or addition of one or plural amino acids and having a herbicide-resistant activity.
