Methods for the production of reversibly male-sterile plants by introduction of a polynucleotide encoding a cytokinin oxidase are disclosed along with nucleic acid constructs and transformed cells useful in the production of such plants. Also disclosed is the use of plants containing recombinant nucleic acid sequences in preventing pollination of plants with pollen containing one or more transgenes and in the introduction of economically important traits into elite varieties of plants.

Reversible male sterility in transgenic plants by expression of cytokinin oxidase

A method for the identification of peptides having an affinity for the surface of fungi is provided as is a method for the identification of peptides capable of affecting the development of a fungus. Also provided are compositions containing peptides identified using the method of the present invention. In addition, isolated polynucleotides, vectors, expression cassettes and transformed cells capable of expressing peptides identified by the method of the present invention are provided.

An isolated protein which exhibits cytokinin oxidizing activity selected from the group consisting of SEQ. ID No. 1, a protein having an amino acid sequence which includes the amino acid sequence of SEQ. ID No. 1, a protein having an amino acid sequence which includes a portion of the amino acid sequence of SEQ. ID No. 1, the included portion being at least about 20 amino acid residues in length and conferring the cytokinin oxidizing activity on the protein, and a protein including an amino acid sequence with at least about 65% sequence identity to SEQ. ID No. 1, the remainder of amino acid residues being conservatively substituted. Nucleic acids encoding proteins which exhibit cytokinin oxidizing activity and related compositions and methods are also disclosed.
