The complete mitochondrial genome of the hemiparasitic mistletoe Psittacanthus palmeri (Loranthaceae) and comparative analysis of mitogenomes across Santalales

open access: yesBotan‪ical Sciences
Background: In parasitic plants, it remains uncertain whether size, structure, and mutation rates in the mitogenome aligns with those of other angiosperms, and whether reduction in gene content is found across lineages of parasitic plants.

The complete chloroplast genome of Scurrula chingii (W.C. Cheng) H.S. Kiu (Loranthaceae), a hemiparasitic shrub

open access: yesMitochondrial DNA. Part B. Resources, 2021
Scurrula chingii (W.C. Cheng) H.S. Kiu is a stem hemiparasite of the genus Scurrula in the family Loranthaceae distributed in southwest China and northern Vietnam. Here, we report and characterize the complete plastid genome sequence of S.

Mitochondrial genome evolution in parasitic plants

open access: yesBMC Evolutionary Biology, 2019
Background Parasitic plants rely on their host to cover their nutritional requirements either for their entire life or a smaller part of it. Depending on the level of parasitism, a proportional reduction on the plastid genome has been found.

A new species and a new record of Heisteria Jacq. (Olacaceae s.l.) from the Atlantic Forest of Espírito Santo, Brazil

open access: yesActa Botânica Brasílica, 2022
During taxonomic studies of extra-Amazonian species of Heisteria, a new record (Heisteria maytenoides) and new species (Heisteria longipedicellata) from the Atlantic Forest of Espírito Santo were identified. Morphological descriptions, illustrations, the

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.

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.

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].

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‐
