Abstract
Nearly 20 years have passed since ammonia was recognized as an absolute requirement for somatic embryogenesis (SE) (3, 136) and presumably for andro-genesis and gynogenesis, i.e., gametophytic embryogenesis (GE). Today we still face a major question as to how ammonia is involved in such a transformation in somatic and gametophytic cells. The intervening years have indicated that the answer to this question is not simple.
