title: Cell-cell communication in Arabidopsis early embryogenesis.
abstract: The basic body plan of the adult plant is established during embryogenesis, resulting in the juvenile form of the seedling. Arabidopsis embryogenesis is distinguished by a highly regular pattern of cell divisions. Some of these divisions are asymmetric, generating daughter cells with different fates. However, their subsequent differentiation might still depend on cell-cell communication to be fully accomplished or maintained. In some cases, cell fate specification solely depends on cell-cell communication that in general plays an important role in the generation of positional information within the embryo. Although auxin-dependent signalling has received much attention, other ways of cell-cell communication have also been demonstrated or suggested. This review focuses on aspects of pattern formation and cell-cell communication during Arabidopsis embryogenesis up to the mid-globular stage of development.
