The basic body organisation of Arabidopsis is established by position-dependent cell fate specification during early embryogenesis. Initially, the zygote divides asymmetrically to produce a small apical cell and a large basal cell. The apical cell will give rise to the embryo except for that part of the primary root meristem that is derived from the basal cell, which also and primarily generates an extra-embryonic suspensor. A major focus of our research is the establishment of apical versus basal cell fate as well as the interaction between the two cell lineages that results in the initiation of the primary root meristem.
