    摘要: The present inventors have discovered that antisense suppression of a chlorophyll synthase (CS) gene results in plants exhibiting one or more of chlorosis, reduced growth, and altered development. Thus, the present inventors have discovered that the protein encoded by the CS gene is essential for normal plant growth and development, and is useful as a target for the identification of compounds as antibiotics and herbicides, especially herbicides. The present invention is directed to methods for identifying inhibitors of a CS enzyme by incubating a CS polypeptide with a chlorophyllide and a phopholipid substrate in the presence and absence of a test compound under conditions suitable for the CS enzyme activity, adding a solution to the incubation reactions comprising a water immiscible organic solvent, a water-soluble alcohol, and a water-soluble dye that absorbs in the range of one or both the excitation and emission wavelength ranges of the chlorophyllide substrate, and measuring the fluorescence of the incubation reactions at from about 650 to 750 nm, using from about 425 to 445 nm as excitation wavelength, wherein a decrease in the fluorescence in the presence of the test compound indicates that the compound is a CS inhibitor.

    摘要: The present invention relates to isolated nucleic acid molecules and their corresponding encoded polypeptides able confer the trait of modulated plant size, vegetative growth, organ number, plant architecture, growth rate, seedling vigor, growth rate, fruit and seed yield, tillering and/or biomass in plants. The present invention further relates to the use of these nucleic acid molecules and polypeptides in making transgenic plants, plant cells, plant materials or seeds of a plant having plant size, vegetative growth, organ number, plant architecture, growth rate, seedling vigor and/or biomass that are altered with respect to wild type plants grown under similar conditions.
