SummaryThe basic features of the body organisation of adult plants are established during embryogenesis. This process starts from the fertilized egg cell (zygote), which divides into an apical embryonic cell and a basal extra-embryonic cell. How this initial difference originates with input from the YODA pathway is briefly discussed. These cells give rise to embryo and extra-embryonic suspensor, respectively. The embryonic cells then 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.
