Abstract: A method of producing a lunasin polypeptide in a plant includes expressing a fusion protein including the lunasin polypeptide in the plant and cleaving the lunasin polypeptide from the fusion protein.

Abstract: The present inventors have discovered that chorismate mutase and chorismate synthase are essential for plant growth. Specifically, the inhibition of chorismate mutase or chorismate synthase gene expression in plant seedlings results in severe chlorosis, reduced growth and developmental abnormalities. The inventors have proven that chorismate synthase and chorismate mutase can be used as targets for the identification of herbicides. Thus, the invention provides methods for the identification of chemicals that modulate chorismate synthase and chorismate mutase biochemical reactions. The methods of the invention are useful for the identification of herbicides and for the inhibition of plant growth and development.

Abstract: The present inventors have discovered that Mg-chelatase is essential for the growth of Arabidopsis. Specifically, the inhibition of Mg-chelatase CHL H gene expression in Arabidopsis seedlings results in varying levels of chlorosis (yellowing), significantly reduced growth and developmental abnormalities. Thus, Arabidopsis Mg-chelatase can be used as a target for the identification of herbicides. Accordingly, the present invention provides methods for the identification of compounds that modulate Arabidopsis Mg-chelatase expression or activity, comprising: contacting a compound with a Arabidopsis Mg-chelatase, or a subunit thereof, and detecting the presence and/or absence of binding between said compound and said Mg-chelatase, or detecting a change in Mg-chelatase expression or activity. The methods of the invention are useful for the identification of herbicides and other compounds that can modulate plant growth and development.

Abstract: Isolated nucleotide compositions and sequences are provided for Arabidopsis thaliana genes. The nucleic acid compositions find use in identifying homologous or related genes; in producing compositions that modulate the expression or function of its encoded protein, mapping functional regions of the protein; and in studying associated physiological pathways. The genetic sequences may also be used for the genetic manipulation of cells, particularly of plant cells. The encoded gene products and modified organisms are useful for screening of biologically active agents, e.g. fungicides, insecticides, etc.; for elucidating biochemical pathways; and the like.

Abstract: The present inventors have discovered that chorismate mutase and chorismate synthase are essential for plant growth. Specifically, the inhibition of chorismate mutase or chorismate synthase gene expression in plant seedlings results in severe chlorosis, reduced growth and developmental abnormalities. Thus, in one aspect the invention provides compositions for the modulation of plant growth or development comprising chorismate synthase and chorismate mutase antisense and sense polynucleotides, dsRNA and ribozymes, and related expression cassettes and vectors. The compositions of the invention are particularly useful for the modulation and inhibition of plant growth. The invention further provides plants, plant cells, and seeds containing the polynucleotides of the invention.

Abstract: The present inventors have discovered that pyruvate orthophosphate dikinase (PPDK) is essential for plant growth. Specifically, the inhibition PPDK gene expression in plant seedlings results in significant developmental abnormalities, including abnormal cotyledon development, abnormal or aborted primary leaf development and significantly reduced growth. Thus, PPDK can be used as a target for the identification of herbicides. Accordingly, the present invention provides methods for the identification of compounds that inhibit PPDK expression or activity, comprising: contacting a compound with a PPDK and detecting the presence and/or absence of binding between said compound and said a PPDK, or detecting a decrease in PPDK expression or activity. The methods of the invention are useful for the identification of herbicides.
