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.

Floristic composition and turnover analysis in Dahomey Gap and the surrounding sub‐humid Togolese mountain minor forest refuges: Importance for biogeography and biodiversity conservation in sub‐Saharan Africa

Ecology and Evolution, Volume 12, Issue 10, October 2022., 2022
The origin of the DG is one of the central biogeographical questions in sub‐Saharan Africa, which has been addressed in recent phylogenetic studies. Till date, no study based on large floristic data collected in the DG has addressed this question. Our work, based on large floristic data collected in the DG and compared with those of regional floras, is

An efficient and effective RNA extraction protocol for ferns. [PDF]

Appl Plant Sci
Abstract Premise The extraction of high‐quality RNA is the critical first step for the analysis of gene expression and gene space. This remains particularly challenging in plants, and especially in ferns, where the disruption of the cell wall and separation of organic compounds from nucleic acids is not trivial.

High‐speed video and plant ultrastructure define mechanisms of gametophyte dispersal

Applications in Plant Sciences, Volume 10, Issue 2, March-April 2022., 2022
Abstract Dispersal of gametophytes is critical for land plant survivorship and reproduction. It defines potential colonization and geographical distribution as well as genetic mixing and evolution. C. T. Ingold's classic works on Spore Discharge in Land Plants and Spore Liberation review mechanisms for spore release and dispersal based on real‐time ...

Edaphic heterogeneity and the evolutionary trajectory of Amazonian plant communities

Ecology and Evolution, Volume 11, Issue 24, Page 17672-17685, December 2021., 2021
We investigated the phylogenetic structure of Amazonian fern and palm communities on edaphically distinct sites. We show that phylogenetic community structure varies along a soil base cation concentration gradient within non‐inundated Amazonian rain forests.

First phylogenetic analysis of Dryophthorinae (Coleoptera, Curculionidae) based on structural alignment of ribosomal DNA reveals Cenozoic diversification

Ecology and Evolution, Volume 11, Issue 5, Page 1984-1998, March 2021., 2021
This study presents the first phylogeny of the palm weevil subfamily Dryophthorinae (1,200 species, 153 genera), a group that is mainly associated with monocots and includes major pests, such as the Red and South American Palm Weevils. This study includes genetic sampling of all major lineages worldwide, integrated structural alignment of ribosomal DNA

Traditional Medicinal Plants as a Source of Antituberculosis Drugs: A System Review

BioMed Research International, Volume 2021, Issue 1, 2021., 2021
Medicinal plants are the chief components in the different oriental formulations in different traditional medical systems worldwide. As a thriving source of medicine, the medicinal plants with antituberculosis (TB) properties inspire the pharmacists to develop new drugs based on their active components or semimetabolites.
