Synchronizing flower development

We have attempted to modify the tomato inflorescence in order to synchronize flower development. Constructs to modify expression of two key regulatory genes, FALSIFLORA (FALS) and SELF PRUNING (SP), have been made and transgenic plants with the desired phenotypes were obtained, albeit with accompanying developmental defects. Mapping of the An, wiry4 and S mutations has been achieved down to 1cM intervals, and the forthcoming tomato genome sequence should facilitate the identification of these genes in the near future.
