<p>Provided are methods for controlling or altering the growth characteristics of a plant or of an organ or tissue or cell of this plant. This method comprises introduction and/or expression of one or more Growth Regulating Proteins functional in a plant or parts thereof and/or one or more DNA sequences encoding such proteins. Another method comprises contacting a plant or plant tissue with the purified Growth Regulated Protein or the active product derived from it. Provided are also DNA sequences encoding plant Growth Regulating Protein(s) as well as methods for obtaining the same. Furthermore, vectors comprising said DNA sequences are described, wherein the DNA sequences are operatively linked to regulatory elements allowing expression in prokaryotic and/or eukaryotic host cells. In addition, proteins encoded by said DNA sequences, antibodies to said proteins and methods for their production are provided. Furthermore, regulatory sequences, which naturally regulate the expression of the above-described DNA sequences, are described. Methods for the identification of compounds being capable of interacting with said Growth Regulating Proteins are described as well. Furthermore, transgenic plant cells, plant tissues and plants containing the above-described DNA sequences and vectors are described, as well as the use of the aforementioned DNA sequences, vectors, proteins, antibodies, regulatory sequences and/or compounds identified by the method of the invention in plant cell and tissue culture, plant breeding and/or agriculture.</p> |
