Signaling in plant embryogenesis.
Embryogenesis is a critical stage of the sporophytic life cycle during which the basic body plan of the plant is established. Although positional information is implicated to play a major role in determining embryo cell fate, little is known about the nature of positional signals. Recent studies show that the monopterous and hobbit mutations reveal signaling during patterning of the embryonic axis. The LEAFY COTYLEDON1 and PICKLE genes have been implicated to play important roles in controlling embryo development.
