Arabidopsis embryogenesis.
Embryogenesis in higher plants consists of two major phases, morphogenesis and maturation. Morphogenesis involves the establishment of the embryo's body plan, whereas maturation involves cell expansion and accumulation of storage macromolecules to prepare for desiccation, germination and early seedling growth. Arabidopsis mutants showing defects in embryogenesis have provided information for understanding the events that govern embryo formation through molecular, genetic and biochemical analyses. Thus, many of the processes that underlie embryogenesis are beginning to be understood. In this chapter, we focus on genes that play key roles in the morphogenesis phase of Arabidopsis embryogenesis.
