Molecular data from isozyme analyses were used to characterize levels and patterns of genetic diversity in populations of the neotropical cheilanthoid fern Hemionitis palmata. All populations exhibited lower levels of genetic diversity than most other fern species previously studied. Variability in fixation indices and estimated intragametophytic selfing rates suggest that the predominant mating system varies from outcrossing to moderate levels of selfing among populations. Populations were… 

Diversity, genetic structure and evidence of outcrossing in British populations of the rock fern Adiantum capillus‐veneris using microsatellites

Inferences are made on the factors determining the observed levels and patterns of genetic variation and the possible evolutionary history of the populations within the UK and Ireland where this species grows at the northern edge of its range.

Population Genetic Variation in the Tree Fern Alsophila spinulosa (Cyatheaceae): Effects of Reproductive Strategy

Sexual recombination is the predominant source of genetic variation in most of the examined populations of A. spinulosa, however, somatic mutation contributes most to the genetic variations in population ZHG.

High genetic variability revealed by allozymic loci in the narrow endemic fern Polystichum otomasui (Dryopteridaceae)

High genetic variability in the narrow endemic fern Polystichum otomasui may have resulted from a recent rapid decline in the population and/or the large effective population size resulting from the extensive gene flow among the populations.

Gene Flow among Populations of Two Rare Co-Occurring Fern Species Differing in Ploidy Level

The results suggest that in ferns, the ability to colonize new habitats and the gene flow among existing populations are affected by the mating system.

Genetic variation and evolutionary history of the Macaronesian fern Asplenium hemionitis L.

Population genetic analysis based on isozyme markers shows that whereas outcrossing appears to be the prevailing breeding system in populations of A. hemionitis, there is evidence for inbreeding, which may be associated with limited spore dispersal and fine structuring within populations.

Diversity and genetic differentiation among subpopulations of Gliricidia sepium revealed by PCR-based assays

A polymorphism identified within the maternally inherited mitochondrial V7 srRNA product, which relied on digestion with restriction endonucleases, confirmed the genetic subdivision identified with RAPDs, and suggested a relatively limited role for seed in gene dispersal.

Mixed mating system in the fern Asplenium scolopendrium: implications for colonization potential.

While selfing facilitates initial colonization success, inbreeding depression promotes genetically diverse populations through outcrossing in A. scolopendrium.

Sexual expression and genetic diversity in populations of Cryptogramma crispa (Pteridaceae).

The reproductive biology of Cryptogramma crispa, a tetraploid species with a broad circumboreal and alpine distribution, was studied in the laboratory by growing gametophytes in plates with both solidified agar media and sterilized soil and indicates a level of genetic variability that would be expected in an outcrossing species.

An analysis of genetic variation in natural populations of Sticherus flabellatus [R. Br. (St John)] using amplified fragment length polymorphism (AFLP) markers

The findings suggest that the breeding system of S. flabellatus is predominantly inbreeding, with genetic diversity maintained by occasional outcrossing in larger populations, which could provide evidence to support the proposal to protect natural stands of S., which has implications for the Australian horticulture industry.

POPULATION STRUCTURE AND ESTIMATES OF GENE FLOW IN THE HOMOSPOROUS FERN POLYSTICHUM MUNITUM

Levels and distribution of genetic variation were investigated in the homosporous fern, Polystichum munitum, and there were no significant deviations from Hardy‐Weinberg genotypic expectations.

BREEDING SYSTEM OF THE FERN DRYOPTERIS EXPANSA: EVIDENCE FOR MIXED MATING

This study indicates that just as in angiosperms, a variety of breeding systems operates in homosporous ferns, ranging from extreme inbreeding, through mixed mating to outcrossing.

Estimates of Gene Flow, Genetic Substructure and Population Heterogeneity in Bracken (pteridium aquilinum)

The data indicate that, compared with other species, there is very little genetic differentiation among British populations of bracken, and it appears that the whole island is behaving as a single randommating population.

Genetic variation in the homosporous fern Pellaea andromedifolia

The results suggest that genetic variation in sexual homosporous vascular plants is produced by cross fertilization of genetically different gametes and may not result from pairing between homoeologous chromosomes carrying duplicated loci as previously thought.

Genetic variation and population structure in the fern blechnum spicant (Blechnaceae) from western North America

It appears that the outcrossing mating system and effective mechanism of spore dispersal in B. spicant may account for the general lack of genetic structure within populations of this species, which is consistent with data for angiosperms and gymnosperms.

Enzyme Variability and Modes of Evolution in Bommeria (Pteridaceae)

The hypotheses that the mountains of west-central Mexico are the center of origin of Bommeria and that the triploid apomict B. pedata was not derived through hybridization among extant sexual species are supported.

ESTIMATES OF INTRAGAMETOPHYTIC SELFING AND INTERPOPULATIONAL GENE FLOW IN HOMOSPOROUS FERNS

Estimates of rates of intragametophytic selfing, levels of interpopulational gene flow, and the FST values indicate little genetic divergence among populations for all species except Dryopteris expansa, which exhibits significant levels ofinter populational genetic differentiation.

Genetic load and long-distance dispersal in Asplenium platyneuron

The failure of gametophytes from coal-spoil plants to produce sporophytes with even greater success may result from homoeologous chromosome pairing and recombination at meiosis which allows production of variable spores and expression of genetic load from plants produced by self-fertilization of single gametphytes.

Genetic evidence for allopolyploidy in the neotropical fern hemionitis pinnatifida (Adiantaceae) and the reconstruction of an ancestral genome

Genetic evidence from enzyme electrophoresis and restriction site analyses of cpDNA was employed to explore the origin of the tetraploid Hemionitis pinnatifida and demonstrated that the missing ancestor was genetically more similar to H. palmata than either of these species is to the other diploid species surveyed.

ELECTROPHORESIS IS MODIFYING OUR CONCEPTS OF EVOLUTION IN HOMOSPOROUS PTERIDOPHYTES

The accumulated data suggest that the genetic system of homosporous pteridophytes differs fundamentally from that of seed plants, which may be the result of repeated cycles of allopolyploidy followed by gene silencing and extinction of progenitor taxa.
