Oogenesis of Lygodium japonicum (Thunb.) Sw. is studied using TEM and cytochemical techniques. The early development of the archegonia of L. japonicum is similar to those of the core-leptosporangiate ferns. A mature archegonium always contains an egg

Premise of research. In advanced ferns that possess an egg envelope and a fertilization pore, a sac that persistently blocks the fertilization pore is considered a barrier for preventing polyspermy. However, for those ferns with no egg envelope and f

Oogenesis in the fern Adiantum flabellulatum was studied using transmission electron microscopy. The newly formed egg is closely appressed to the archegonial jacket cells. Plasmodesmata connect the egg and the ventral canal cell, but are absent betwe
