Genes Translocated into the Plastid Inverted Repeat Show Decelerated Substitution Rates and Elevated GC Content. [PDF]

, 2016
Plant chloroplast genomes (plastomes) are characterized by an inverted repeat (IR) region and two larger single copy (SC) regions. Patterns of molecular evolution in the IR and SC regions differ, most notably by a reduced rate of nucleotide substitution ...

Character evolution of modern eupolypods supports the assignment of the fossil fern Cretacifilix fungiformis to Dryopteridaceae

Frontiers in Ecology and Evolution, 2023
The fossil fern species Cretacifilix fungiformis from mid-Cretaceous Kachin amber from Myanmar was previously assigned to eupolypod ferns for having sporangia with a vertical annulus and sporangial stalks 2–3 cells thick, along with monolete spores with ...

Revision of the Barremian fern Coniopteris laciniata from Las Hoyas and El Montsec (Spain): Highlighting its importance in the evolution of vegetation during the Early Cretaceous

TAXON, Volume 72, Issue 3, Page 625-637, June 2023., 2023
Abstract The species Coniopteris laciniata and Sphenopteris wonnacottii are heterophyllous ferns recovered from two Spanish Barremian localities, Las Hoyas and El Montsec respectively. The similarities between these species, observed in a study of a total of 66 hand specimens from both localities, indicate that they are conspecific.

Environmentally driven extinction and opportunistic origination explain fern diversification patterns. [PDF]

, 2017
Combining palaeontological and neontological data offers a unique opportunity to investigate the relative roles of biotic and abiotic controls of species diversification, and the importance of origination versus extinction in driving evolutionary ...

Deep reticulation: the long legacy of hybridization in vascular plant evolution

The Plant Journal, Volume 114, Issue 4, Page 743-766, May 2023., 2023
SUMMARY Hybridization has long been recognized as a fundamental evolutionary process in plants but, until recently, our understanding of its phylogenetic distribution and biological significance across deep evolutionary scales has been largely obscure. Over the past decade, genomic and phylogenomic datasets have revealed, perhaps not surprisingly, that

Synopsis of Diplazium (Polypodiales: Athyriaceae) from Argentina

Phytotaxa, 2017
The first treatment of the Argentinian representatives of Diplazium (Athyriaceae) is presented. In the country, the genus is represented by eight species, all of which inhabit the Yungas and Parana rainforests. Identification keys, comments, illustrations, and ecological remarks for the species are presented. Diplazium divergens, D. moccennianum, and D.

Anatomical examination of the petiole of eupolypods I (Polypodiales)

Biodiversitas Journal of Biological Diversity, 2020
Abstract. Tan JMP, Banaticla-Hilario MC, Malabrigo P, Angeles MD, JR Buot IE. 2020. Anatomical examination of the petiole of eupolypods I (Polypodiales). Biodiversitas 21: 1767-1777. The efficiency of petiole anatomy characters in identifying and describing the species and families of eupolypods I (Polypodiales) were explored.

Low‐copy nuclear data confirm rampant allopolyploidy in the Cystopteridaceae (Polypodiales) [PDF]

TAXON, 2014
AbstractHere we present the first nuclear phylogeny for Cystopteridaceae (Polypodiales), using the single‐copy locusgapCp“short”. This phylogeny corroborates broad results from plastid data in demonstrating strong support for the monophyly of the family's three genera—Cystopteris, Acystopteris, andGymnocarpium—and of the major groups withinCystopteris ...

Phylogenetic revision of Dennstaedtioideae (Dennstaedtiaceae: Polypodiales) with description of Mucura, gen. nov.

TAXON, 2022
AbstractWe undertook a molecular phylogenetic revision of hayscented ferns (Dennstaedtiaceae: Dennstaedtioideae) using four plastid markers. Our sampling represents ca. 40% of the extant diversity and includes the type species for each of the relevant segregate genera.
