Abstract: The invention generally relates to clavata1 nucleic acids, proteins, and antibodies, and to plants transformed with clavata1 nucleic acids having altered phenotypes.

Abstract: The invention includes transformed plants having at least one cell transformed with a modified ETR nucleic acid. Such plants have a phenotype characterized by a decrease in the response of at least one transformed plant cell to ethylene as compared to a plant not containing the transformed plant cell. Tissue and/or temporal specificity for expression of the modified ETR nucleic acid is controlled by selecting appropriate expression regulation sequences to target the location and/or time of expression of the transformed nucleic acid. The plants are made by transforming at least one plant cell with an appropriate modified ETR nucleic acid, regenerating plants from one or more of the transformed plant cells and selecting at least one plant having the desired phenotype.

Abstract: The invention includes plants having at least one cell transformed with a vector comprising at least a portion of an agamous nucleic acid. Such plants have a phenotype characterized by altered floral development such as an AG or AP2 phenotype. The invention also includes vectors comprising at least a portion of an agamous nucleic acid operably linked to a promoter other than the promoter naturally associated with the agamous nucleic acid. In an alternate embodiment, the vector comprises at least a portion of an agamous nucleic acid operably linked in an antisense orientation to a promoter. The invention also includes methods using such vectors for producing plants having altered floral development.
