Simultaneous Inference of Flora‐Wide Nuclear and Plastid Phylogenies Using Angiosperms353 Sequence Capture Data

Molecular Ecology Resources, Volume 26, Issue 7, October 2026.
ABSTRACT Accurate knowledge of phylogenetic relationships and divergence time among plant species composing a regional flora is crucial for understanding the origin of the biodiversity patterns we observe today. Despite advances in phylogenomics, resources available for reconstructing regional phylogenies are still largely incomplete and poorly ...

Large‐scale nuclear and plastid phylogenomic analyses inform an updated Angiosperm Phylogeny Group classification: APG V

Journal of Systematics and Evolution, Volume 64, Issue 5, Page 845-874, September 2026.
This revision of the APG classification considers the extensive recent analyses of hundreds of nuclear and plastid genes for many angiosperm species. Although previous versions of the APG classification were largely based on uniparentally inherited markers (plastid DNA, largely maternally inherited), there has emerged since APG IV extensive evidence of

Beyond the Paddy Fields: Riparian Reed Beds as Essential Natural Habitat for the Critically Endangered Suweon Treefrog, Dryophytes suweonensis

Ecology and Evolution, Volume 16, Issue 8, August 2026.
This figure shows the true habitat type of Dryophytes suweonensis that this paper aims to demonstrate. ABSTRACT The Suweon treefrog (Dryophytes suweonensis (Kuramoto, 1980)), a critically endangered amphibian endemic to the Korean Peninsula, is widely regarded as being closely associated with rice paddies.

Leveraging machine learning and citizen science data to describe flowering phenology across South Africa

PLANTS, PEOPLE, PLANET, Volume 8, Issue 4, Page 1132-1144, July 2026.
Recent shifts in flowering times are an index of, and a response to, human driven climate change. However, most information on these flowering changes is heavily skewed to the northern hemisphere. This imbalance limits our understanding of how climate change is affecting ecosystems, including the mismatches of flowering times between species, increased

The Structure of Carboxyl Methyltransferase Provides Insights Into the Substrate Specificity and Divergent Evolution of Iridoid

Plant Biotechnology Journal, Volume 24, Issue 6, Page 3708-3722, June 2026.
ABSTRACT Iridoids constitute a prominent class of plant‐specialised metabolites, with carbocyclic iridoids (e.g., geniposide) and secoiridoids (e.g., loganin) diverging early in their biosynthetic pathways. This divergence is marked by substrate‐specific carboxyl methyltransferases—GjGAMT and CrLAMT—that catalyse the decisive methylation step in ...

Description of Gaertnera luteocarpa (Gentianales: Rubiaceae), with two subspecies, a new forest shrub species from Liberia, Ivory Coast and Ghana

European Journal of Taxonomy, 2015
Gaertnera luteocarpa sp. nov., with two subspecies, is described and illustrated. The new species resembles G. spicata K.Schum. but has yellow, not reddish, fruits. With G. cooperi and G. aurea it shares the ruminate endosperm.
