Duplications and Expression of DIVARICATA-Like Genes in Dipsacales [PDF]

open access: yesMolecular Biology and Evolution, 2009
The genetics underlying flower symmetry shifts between radial and bilateral symmetry has been intensively studied in the model Antirrhinum majus. Understanding the conservation or diversification of this genetic pathway in other plants is of special interest in understanding angiosperm evolution and ecology. Evidence from Antirrhinum indicates that TCP

Dating the Dipsacales: comparing models, genes, and evolutionary implications [PDF]

open access: yesAmerican Journal of Botany, 2005
Dipsacales is an asterid angiosperm clade of ca. 1100 species, with most of its lineages occupying temperate regions of the Northern Hemisphere. A recent phylogenetic analysis based on 7593 nucleotides of chloroplast DNA recovered a well‐resolved and strongly supported phylogenetic hypothesis, which we use here to estimate divergence times within the ...

Deductive automated pollen classification in environmental samples via exploratory deep learning and imaging flow cytometry

open access: yesNew Phytologist, Volume 240, Issue 3, Page 1305-1326, November 2023., 2023
Summary Pollen and tracheophyte spores are ubiquitous environmental indicators at local and global scales. Palynology is typically performed manually by microscopic analysis; a specialised and time‐consuming task limited in taxonomical precision and sampling frequency, therefore restricting data quality used to inform climate change and pollen ...

Genome‐scale angiosperm phylogenies based on nuclear, plastome, and mitochondrial datasets

open access: yesJournal of Integrative Plant Biology, Volume 65, Issue 6, Page 1479-1489, June 2023., 2023
Genome‐scale angiosperm phylogenies were reconstructed used currently available de novo genome data of 366 angiosperm species from 241 genera belonging to 97 families across 43 of the 64 orders based on orthologous genes from the nuclear, plastid, and mitochondrial genomes of the same species with compatible datasets.

Effect of environmental and spatial factors on the phylogenetic and functional diversity of the Mediterranean tree communities of Europe

open access: yesPlant Biology, Volume 25, Issue 4, Page 631-645, June 2023., 2023
For implementation of sustainable forest ecosystem management, phylogenetic information is key for conservation priorities and assessing ecosystem functioning. Abstract The tree flora of the Mediterranean Basin contains an outstanding taxonomic richness and a high proportion of endemic taxa.

High‐molecular‐weight DNA extraction for long‐read sequencing of plant genomes: An optimization of standard methods

open access: yesApplications in Plant Sciences, Volume 11, Issue 3, May-June 2023., 2023
Abstract Premise Developing an effective and easy‐to‐use high‐molecular‐weight (HMW) DNA extraction method is essential for genomic research, especially in the era of third‐generation sequencing. To efficiently use technologies capable of generating long‐read sequences, it is important to maximize both the length and purity of the extracted DNA ...

A field‐capable rapid plant DNA extraction protocol using microneedle patches for botanical surveying and monitoring

open access: yesApplications in Plant Sciences, Volume 11, Issue 3, May-June 2023., 2023
Abstract Premise A novel protocol for rapid plant DNA extraction using microneedles is proposed, which supports botanic surveys, taxonomy, and systematics. This protocol can be conducted in the field with limited laboratory skills and equipment. The protocol is validated by sequencing and comparing the results with QIAGEN spin‐column DNA extractions ...

Phylogenetic and Comparative Analyses of Complete Chloroplast Genomes of Chinese Viburnum and Sambucus (Adoxaceae)

open access: yesPlants, 2020
Phylogenetic analyses of complete chloroplast genome sequences have yielded significant improvements in our understanding of relationships in the woody flowering genus Viburnum (Adoxaceae, Dipsacales); however, these relationships were evaluated focusing

Coming to America: Multiple Origins of New World Geckos [PDF]

open access: yes, 2011
Geckos in the Western Hemisphere provide an excellent model to study faunal assembly at a continental scale. We generated a time-calibrated phylogeny, including exemplars of all New World gecko genera, to produce a biogeographic scenario for the New ...
