Absence of Complex I Is Associated with Diminished Respiratory Chain Function in European Mistletoe [PDF]

open access: yes, 2018
Parasitism is a life history strategy found across all domains of life whereby nutrition is obtained from a host. It is often associated with reductive evolution of the genome, including loss of genes from the organellar genomes [1, 2].

Progress and problems in the assessment of flower morphology in higher-level systematics [PDF]

open access: yes, 2018
Floral features used for characterization of higher-level angiosperm taxa (families, orders, and above) are assessed following a comparison of earlier (precladistic/premolecular) and current classifications.

The role of Alpine botanical gardens in integrating germplasm bank collections and mission

open access: yesPLANTS, PEOPLE, PLANET, Volume 8, Issue 2, Page 680-692, March 2026.
This study underscores the vital role of Alpine botanical gardens (ABGs) in safeguarding Europe's alpine biodiversity amid climate change and habitat loss. By acting as living laboratories and reservoirs of plant genetic resources, ABGs bridge ex situ and in situ conservation, supporting ecosystem resilience and informing restoration strategies.

Epiparasitism in Phoradendron durangense and P. falcatum (Viscaceae) [PDF]

open access: yes, 2009
Phoradendron, the largest mistletoe genus in the New World, extends from temperate North America to temperate South America. Most species are parasitic on terrestrial hosts, but a few occur only, or primarily, on other species of Phoradendron.

Spermatophyta Molecular Clock: Time Drift and Recent Acceleration

open access: yesPlant-Environment Interactions, Volume 6, Issue 5, October 2025.
Exponential increase in the base substitution rate in recent geologic time. ABSTRACT Angiospermae radiation is widely recognized as a mid‐Cretaceous event, but the adaptive radiation of Asarum and Viola as spring ephemerals also occurred during the Quaternary. To better understand the evolution of Angiospermae through geological time, a robust and well‐

Hot node limitations and impact of taxonomic resolution on phylogenetic divergence patterns: A case study on Ecuadorian ethnomedicinal flora

open access: yesPLANTS, PEOPLE, PLANET, Volume 7, Issue 3, Page 644-653, May 2025.
Novel phylogenetic approaches have emerged in recent years to study traditional medicinal plants, aiming to identify potential sources of new drugs. This line of research holds considerable promise yet remains in its early stages. Here, we examine the prevalent methods employed in the field, revealing the impact of methodological choices that have ...
