The ploidy levels, morphologies of gametophytes and young sporophytes, and reproductive modes of Pteris cretica, P. pellucidifolia, and P. wulaiensis were determined in this study. Pteris cretica and P. wulaiensis were diploid while P. pellucidifolia was triploid. Sporophytes of all three species produced 32-spored sporangia. Spore sizes of the triploid P. pellucidifolia were significantly larger than those of the other two diploid species. However, the frequencies of normal spores were lower… Expand

Gametophyte Morphology and Development of Six Species of Pteris (Pteridaceae) from Java Island Indonesia
TLDR
The gametophyte development of observed Pteris spesies are varied in six characters including the number of filament cell, germinated time, formation time of notch and gametangia, margin shape, and development type. Expand
Gametophyte Morphology and Development of Three Species of Cyrtogonellum Ching (Dryopteridaceae)
Abstract Gametophyte morphology and development of three species of Cyrtogonellum Ching (Dryopteridaceae) were described with the aim to increase our knowledge on the gametophytic stage of this fernExpand
Polyploidy and Speciation in Pteris (Pteridaceae)
TLDR
The diverse ploidy levels of Pteris species suggest that these species have a complex evolutionary history and their taxonomic problems require further clarification. Expand
Gametophytic phase of Doryopteris triphylla (Pteridaceae, Polypodiopsida)
TLDR
Doryopteris triphylla gametophytes exhibited somewhat peculiar features: the apical cell divided longitudinally, the first meristematic cell was rectangular, and archegoniate prothalli appeared much before than antheridiate ones. Expand
Reproductive Biology of Aglaomorpha cornucopia (Copel.) M.C. Roos, a Rare and Endemic Fern from the Philippines
TLDR
Results of this study suggest that cold temperature spore storage and in vitro culture offer reliable techniques for conserving this rare fern. Expand
Apomixis and reticulate evolution in the Asplenium monanthes fern complex.
TLDR
Multiple origins of apomixis are inferred, in both alloploid and autoploid forms, within the A. monanthes clades. Expand
Between sexual and apomictic: unexpectedly variable sporogenesis and production of viable polyhaploids in the pentaploid fern of the Dryopteris affinis agg. (Dryopteridaceae).
TLDR
The pentaploid Dryopteris × critica hybrid is partly fertile (89-94% of aborted spores) and shows unstable sporogenesis with sexual and apomictic reproduction combined, which documents the mixed reproductive mode of a hybrid between apoictic and sexual ferns. Expand
Pteris latipinna sp. nov. (Pteridaceae), a new species segregated from Pteris fauriei
TLDR
It was confirmed that this species is phylogenetically separated from the other East Asian Pteris species, except for a morphologically distinct species P. arisanensis, by means of chloroplast genes, rbcL and matK. Expand
Chromosomal Aberrations and Apomictic Behavior in Two Cytotypes of Pteris cretica L. from Western Himalayas
TLDR
Meiotic analysis of different accessions of P. cretica revealed that meiotic course was highly irregular with reduced spore fertility and high incidence of micronuclei in triploid cytotype is a conspicuous phenomenon among other meiotic abnormalities. Expand
Ecological Significance of Brassinosteroids in Three Temperate Ferns
TLDR
Brassinosteroid application seems to regulate fern spore germination by modulating antheridiogen levels, and the effects range from increasing the development velocity in P. lonchitis to the independence of P. aquilinum and P. vittata. Expand

Apogamy Induction in Ceratopteris richardii
TLDR
The successful induction of apogamy is reported in the model fern Ceratopteris richardii by culturing gametophytes in the presence of high levels of exogenous sugars, which establishes an experimental system that will allow genes that are important in apogamous production of sporophytes to be identified.

TLDR

TLDR
Mercklin (1850) found cells in the prothallium of Pteris sulcata like those observed by Leszcyc-Suminski, and Mercklin's figure, although somewhat diagrammatic, suggests that the embryo had been apogamously produced. Expand
