Electrophoresis is modifying our concepts of evolution in
homosporous pteridophytes.
Cytology of germination of spores of
homosporous ferns.
However, mating system estimates from
homosporous ferns indicate that polyploids are often highly setting relative to diploid races (Masuyama and Watano 1990; Watano and Masuyama 1991).
In most
homosporous ferns, spore germination produces a primary rhizoid, followed by a germinal multicellular filament subsequent prothallial development based on the plane of cell division, and in the direction of the growth of the rhizoid and prothallial cell, this pattern of development was observed in A.
The contribution by the gametophyte to the classification of the
homosporous ferns.
Heterozygosity for recessive lethals in
homosporous fern populations: Thelypteris palustris and Onoclea sensibilis.
development of
homosporous ferns focusing on meristem
spores of both
homosporous and heterosporous Filicopsida.
Population structure and estimates of gene flow in the
homosporous fern Polystichum munitum.
However, most ferns are
homosporous, producing one type of spore that, after germination, will produce a gametophyte.
Soltis, Genetic evidence suggests that
homosporous ferns with high chromosome numbers are diploid.
