Contrasting Phylogenetic Signals in Flowering and Fruiting Phenology at Species and Assemblage Scales in a Climbing Plant Community

Journal of Vegetation Science, Volume 36, Issue 6, November/December 2025.
This study examined the phylogenetic conservatism of flowering and fruiting in 78 climbing plant species relative to environmental gradients in a South Brazilian forest. Although species‐level analysis found a weak phylogenetic signal, a strong influence was detected at the assemblage scale, revealing that evolutionary history mediates the phenology ...

Spermatophyta Molecular Clock: Time Drift and Recent Acceleration

Plant-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‐

Aquilegia B gene homologs promote petaloidy of the sepals and maintenance of the C domain boundary

EvoDevo, 2017
The model Aquilegia coerulea x “Origami” possesses several interesting floral features, including petaloid sepals that are morphologically distinct from the true petals and a broad domain containing many whorls of stamens.

Herbivory Dominates the Spring Diet of American Black Bears (Ursus americanus) in a Wood Bison (Bison bison athabascae) Neonatal Range, Suggesting Minimal Bison Consumption

Ecology and Evolution, Volume 15, Issue 9, September 2025.
In this study, we used scat analysis and DNA metabarcoding to analyze the spring diet of black bears in the neonatal range of a small, threatened wood bison herd in northeast Alberta to assess predation risk of neonate bison. Our results suggest that consumption rates of bison are low and that predation risk to neonate wood bison, during the RLBH's ...

Biogeography of Coptis Salisb. (Ranunculales, Ranunculaceae, Coptidoideae), an Eastern Asian and North American genus

BMC Evolutionary Biology, 2018
Background Numerous studies have favored dispersal (colonization) over vicariance (past fragmentation) events to explain eastern Asian-North American distribution patterns. In plants, however the disjunction between eastern Asia and western North America

LGRPv2: A high‐value platform for the advancement of Fabaceae genomics

Plant Biotechnology Journal, Volume 23, Issue 9, Page 4057-4075, September 2025.
Summary Fabaceae, as one of the most diverse angiosperm families, plays a crucial role in maintaining global ecosystems and advancing human civilization. With the rapid accumulation of legume genomes, we developed LGRPv2 (https://fabaceae.cgrpoee.top), an updated version of the Legume Genomics Research Platform.

Progestogens and androgens influence root morphology of angiosperms in a brassinosteroid‐independent manner

The Plant Journal, Volume 123, Issue 5, September 2025.
Significance Statement Plants produce progesterone and androgens, which alter root morphology in A. thaliana and 60% of tested angiosperms. Brassinosteroids seem uninvolved. Understanding the mechanism is like navigating an unknown city—exemplarily Dittelbrunn (a small village in Bavaria)—where the expected shortcut (interaction with brassinosteroids ...

Placing Nothophylica piloburmensis from Cretaceous amber into the angiosperm phylogeny

TAXON, Volume 74, Issue 4, Page 933-937, August 2025.
Abstract Recently, we redescribed an amber inclusion from mid‐Cretaceous Kachin amber of Myanmar, previously assigned to the extant genus Phylica in Rhamnaceae (core eudicots), and placed it in a new fossil‐genus, Nothophylica. Based on our reconstructions, we identified new floral features and instead suggested affinities within magnoliids, especially

A framework for long‐term environmental monitoring using living plant collections in botanic gardens: A global review and case study from Trinity College Botanic Garden

PLANTS, PEOPLE, PLANET, Volume 7, Issue 4, Page 954-968, July 2025.
Botanic gardens play a crucial role in addressing global environmental challenges by providing a unique setting for long‐term plant studies and engaging the public in climate change awareness. Our review highlights the underuse of these gardens' living collections for monitoring climate impacts, revealing significant gaps in data and phylogenetic ...
