Two cDNA libraries were constructed from microdissected 214 rice proembryos (2-3 d after pollination) and 121 just differentiating young embryos (3-5 d after pollination) respectively through RT_PCR technique.

The zygote divides horizontally and develops into a basal cell and an apical cell which simultaneously divide horizontally and develop to a rectilinear proembryo with four cells.
