Developmental responses to hormones and to environmental inputs can be studied both at the level of individual cells and in multicellular tissues. Molecular techniques including gene inactivation by targeted gene replacement or by RNA interference, together with the nearly completed sequencing of the Physcomitrella patents genome, open the way for detailed study of the functions of genes involved in both development and metabolism.
