Summary
The basic features of the body organisation of adult plants are established during embryogenesis. This process starts from the fertilised egg cell (zygote), which divides into an apical embryonic cell and a basal extra-embryonic cell. This report describes how the embryonic cells generate, in response to the plant hormone auxin, a signal that stimulates the adjacent extra-embryonic cell to initiate the formation of the embryonic root meristem. In addition, attempts to study the origin of the very first difference between apical and basal cell fate are briefly discussed.
