1929 Bull. Torrey Bot. Club 56 285 Guignard..outlines megagametogenesis in this species.
1948 Bot. Rev. 14 4 (note) The first two divisions (Meiosis I and II) of the megaspore mother cell..may be spoken of as constituting ‘megasporogenesis’; the subsequent divisions ending in the differentiation of the egg cell constitute ‘megagametogenesis’.
1975 Acta Histochem. 53 244 Extensive changes in the enzyme activity and reserve substances are demonstrated during megasporogenesis and megagametogenesis.
1998 Developmental Biol. 202 136 Several major events occur during megagametogenesis, including syncitial [sic] nuclear divisions, cellularization, nuclear migration and fusion, and cell death.
