Although many people have expressed alarm that we are witnessing a mass extinction, few projections have been quantified, owing to limited availability of time-series data on threatened organisms, especially plants. To quantify the risk of extinction

Genetic variation and structure of the endangered Lady Fern Athyrium viridescentipes based on ubiquitous genotyping
Autor: Shingo Kaneko, Ayako Izuno, Yuji Isagi, Masayuki Takamiya
Publikováno v: Journal of Plant Research. 125:613-618
To clarify the genetic status and provide effective information for the conservation of Athyrium viridescentipes, a critically endangered fern species with only 103 individuals remaining in the wild, we conducted ubiquitous genotyping to determine th

Species complexes consisting of ill-defined "species" are widely known among ferns, and their involvement with reticulate evolution is expected. Nevertheless approaches to reticulation history with DNA markers are not yet commonly adopted. We have su

Cytological, Morphological, Genetic, and Molecular Phylogenetic Studies on Intraspecific Differentiations within Diplazium doederleinii (Woodsiaceae: Pteridophyta)
Autor: Masayuki Takamiya, Yoko Yatabe, Noriaki Murakami, Noriko Ohta
Publikováno v: International Journal of Plant Sciences. 162:625-636
Two cytotypes, an apomictic triploid (2n=123) and an apomictic tetraploid (2n=164), were found in Japanese Diplazium doederleinii. The cytotypes are clearly distinguishable from each other in phytogeographical, ecological, and morphological character

Publikováno v: Molecular Phylogenetics and Evolution. 15:403-413
Nucleotide sequences of the chloroplast gene rbcL from 42 species of the fern tribe Physematieae (Dryopteridaceae) were analyzed to gain insights into the inter- and intrageneric relationships and the generic circumscriptions in the tribe. The phylog
