Optimizing efficient PCR‐amplifiable DNA extraction from herbarium specimens

Applications in Plant Sciences, Volume 11, Issue 3, May-June 2023., 2023
Abstract Premise The objective of this study was to optimize an existing DNA extraction protocol for recalcitrant plant taxa to obtain high‐quality DNA from preserved herbarium tissue suitable for downstream PCR applications. Methods and Results Leaf tissue from 30 diverse plant species was obtained from the U.S. National Arboretum Herbarium.

Synthesis of Selagibenzophenone A and Its Derivatives for Evaluation of Their Antiproliferative, RORγ Inverse Agonistic, and Antimicrobial Effect**

ChemistrySelect, Volume 8, Issue 7, February 16, 2023., 2023
We report a modular synthesis of unnatural variously substituted derivatives of the natural product selagibenzophenone A. We discovered, that some of the derivatives show promising antiproliferative and potential anti‐inflammatory activity. For both biological effects, the activity of some derivatives is superior to that of the natural compound ...

Biogeochemical niche conservatism relates to plant species diversification and life form evolution in a subtropical montane evergreen broad‐leaved forest

Ecology and Evolution, Volume 12, Issue 12, December 2022., 2022
Our results show that biogeochemical niche conservatism relates to plant species diversification and life form evolution in subtropical forest plants. Furthermore, the strengths of biogeochemical niche conservatism varying among elements and between life forms might be mostly determined by the tempo and mode of OU processes.

Spore morphology of Selaginella borealis, S. sanguinolenta and S. helvetica (Selaginellaceae, Lycopodiophyta)

Turczaninowia, 2019
For the first time we have conducted a study of three species of the genus Selaginella P. Beauv. from Russia: S. sanguinolenta (L.) Spring, S. helvetica (L.) Link and S. borealis (Kaulf.) Rupr. using the method of scanning electron microscopy (SEM). In a

Scrub encroachment promotes biodiversity in temperate European wetlands under eutrophic conditions

Ecology and Evolution, Volume 12, Issue 11, November 2022., 2022
We examine the effects of encroachment on biodiversity along gradients of soil moisture and soil fertility in open and wooded wetlands in Denmark. Our results support existing knowledge of the importance of nutrient poor, wet mires and meadows for rare species but on former arable lands where restoration of infertile habitats is less feasible we ...

High species richness and turnover of vascular epiphytes is associated with water availability along the elevation gradient of Volcán Maderas, Nicaragua

Ecology and Evolution, Volume 12, Issue 11, November 2022., 2022
We documented and examined patterns of species richness and abundance of tropical epiphytes along the entire elevational gradient of an isolated, island volcano. Our complete and detailed sampling along the gradient improves our understanding of vascular epiphyte distribution and its association to weather variables, based on direct observations.

Desiccation tolerance in bryophytes relates to elasticity but is independent of cell wall thickness and photosynthesis

Physiologia Plantarum, Volume 174, Issue 2, March/April 2022., 2022
Abstract Mosses have been found outliers of the trade‐off between photosynthesis and bulk elastic modulus described for vascular plants. Hence, potential trade‐offs among physical features of cell walls and desiccation tolerance, water relations, and photosynthesis were assessed in bryophytes and other poikilohydric species.

A taxonomic revision of Selaginella monospora Spring (Selaginellaceae)

Turczaninowia, 2021
During a taxonomic revision of Selaginella from the Himalaya which is a part of the ongoing “Flora of Pan-Himalaya” project, we studied the taxonomy of Selaginella monospora and its closely related species. We found that S.
