Abstract: This invention relates to an isolated nucleic acid fragment encoding floral development proteins, more specifically FT, TFL or Ap3 homologs. The invention also relates to the construction of a recombinant DNA construct encoding all or a portion of the floral development proteins, in sense or antisense orientation, wherein expression of the recombinant DNA construct results in production of altered levels of the FT, TFL or Ap3 homologs in a transformed host cell.

Abstract: The present invention relates to the generation and use of a cellular array or a cellular array in combination with other genome-registered arrays (an array of arrays) for the determination of gene function and/or perturbation mode of action. Each cellular array consists of a number of microbial strains. Each strain comprises one reporter gene fusion made up of a gene or gene fragment operably linked to a reporter gene. Each gene or gene fragment has been “registered” or mapped to a specific location in the genome of the organism. The genome-registered collection of the invention may be used to determine alterations in gene expression under a variety of conditions. Such collections are amenable to rapid assay and may be used to confirm, correct or augment data generated from DNA micro array technology.
