Definition
A plant embryo development stage (PO:0007631) that occurs during the interval between the first cell division of a plant zygote (PO:0000423) and the onset of the plant globular embryo stage (PO:0001185). Source: POC:Laurel_Cooper, APweb:Glossary, TAIR_curator:Katica_Ilic
Comment
In the case of a nucellar (adventitious) plant embryo (PO:0004537), somatic plant embryo (PO:0025302), microspore-derived cultured plant embryo (PO:0025305), or other embryos that arise through apogamy, the plant proembryo stage (PO:0001180) begins after the division of a single cell that is not a zygote. The plant proembryo stage occurs prior to the differentiation of the three main tissue systems (vascular system (PO:0000034) epidermis (PO:0005679); and the portion of ground tissue (PO:0025059)).
