title: Developmental programmes in floral organ formation.
abstract: In contrast to animals, organogenesis in plants is continuous, allowing development in response to intrinsic and extrinsic signals. Organs arise from primordia formed on the flanks of meristems. The apical meristem produces primordia that acquire leaf identity, while floral meristems form primordia which develop into four organ types: sepals, petals, stamens and carpels. The production of mature organs involves two distinct processes, the initiation of organ primordia and the establishment of meristem, primordia and cell identities. Here we concentrate on floral organogenesis in Arabidopsis and examine the extent to which these processes utilize similar control mechanisms and regulatory molecules.
