Histological Diagnosis and Recovery Regulation of Gametophyte Developmental Disorders During In Vitro Propagation of the Medicinal Fern Cibotium barometz [PDF]
Cibotium barometz (L.) J.Sm., a medicinal fern, relies on three interconnected processes for in vitro propagation: spore germination, ordered gametophyte development, and successful initiation and early establishment of the sporophyte generation. However,

Quantitative live-imaging reveals the dynamics of apical cells during gametophyte development in ferns [PDF]
Meristems in land plants share conserved functions but develop highly variable structures. Meristems in seed-free plants, including ferns, usually contain one or a few pyramid-/wedge-shaped apical cells (ACs) as initials, which are lacking in seed plants.

The development of gametophytes and oogenesis in the fern Pronephrium penangianum
The development of gametophytes and oogenesis in the fern Pronephrium penangianum were investigated using microscopy technology. The results showed that the spores of P. penangianum were brown and dihedral and its spores germinated about 12 d after sowed.

Morphogenesis of the gametophyte of Physematium montevidensis (Woodsiaceae)
In vitro spore culture and gametophyte characteristics may contribute understanding the life cycle in different fern taxa and also to systematic and taxonomic studies. The family Woodsiaceae contains two genera: Physematium and Woodsia.
