Genetic analysis of plant morphogenesis in vitro.

Plant morphogenesis in vitro such as somatic embryogenesis and adventitious organogenesis has provided useful systems for physiological, biochemical, and molecular biological studies on plant development. Advantages of the in vitro systems are currently being combined with genetic techniques to generate new insights into fundamental mechanisms of plant development. This article presents an overview of genetic analysis of plant morphogenesis in vitro including genetic variation of tissue culture responses, mutational analysis of somatic embryogenesis, and mutational analysis of adventitious organogenesis.
