SOME FEATURES IN THE ANATOMY OF THE MALVALES

open access: yesAmerican Journal of Botany, 1915
In the study of the phylogeny of plants there are certain general principles upon which conclusions are based, among.which the law of recapitulation is of the utmost importance. This law in its application to plant anatomy shows that primitive conditions are found in the seedling and in the first annual ring of growth.

Evolutionary dynamics of the chloroplast genome in Daphne (Thymelaeaceae): comparative analysis with related genera and insights into phylogenetics

open access: yesFEBS Open Bio, Volume 16, Issue 3, Page 503-519, March 2026.
Comparative analysis of chloroplast genomes from 14 genera of Thymelaeaceae revealed variation in gene content, ranging from 128 to 142 genes, primarily influenced by IR expansion/contraction events and pseudogenization of ndhF, ndhI, and ndhG. Two large inversions were detected within the large single‐copy region, including a synapomorphic inversion ...

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.

Winter diet of Korean long‐tailed goral Naemorhedus caudatus: natural foraging and post‐wildfire supplementary feeding revealed by DNA metabarcoding

open access: yesWildlife Biology, Volume 2026, Issue 1, January 2026.
Understanding the winter diets of endangered ungulates is critical for developing effective conservation strategies in temperate ecosystems, where seasonal fluctuations significantly affect food availability. The long‐tailed goral Naemorhedus caudatus, an herbivorous ungulate listed as a category I ‘Endangered species' (EN) under the Korean Wildlife ...

Dual Isotope Analysis Reveals Phylogenetic Patterns and Novel Insights Into Methoxy Group Synthesis of Structural Biomolecules in Leaf and Woody Plant Tissues

open access: yesPlant, Cell &Environment, Volume 48, Issue 12, Page 8483-8501, December 2025.
ABSTRACT Stable carbon and hydrogen isotopes of wood methoxy groups (δ2Hmeth, δ13Cmeth), mainly sourced by structural biomolecules like lignin and pectin, provide important insights into climatic, hydrological and physiological conditions. This study systematically investigated species‐specific δ2Hmeth and δ13Cmeth variations in leaves and woody twigs ...

The complete chloroplast genome sequence of Chengal (Neobalanocarpus heimii, Dipterocarpaceae), a durable tropical hardwood

open access: yesMitochondrial DNA. Part B. Resources, 2019
Known for its durable timber quality, Neobalanocarpus heimii (King) Ashton is a highly sought after tree species endemic to the Malay Peninsula. Due to its scarcity and high value, the tree is classified under the IUCN Red List categories of Vulnerable ...

Phylogenetic inference in Rafflesiales: the influence of rate heterogeneity and horizontal gene transfer

open access: yesBMC Evolutionary Biology, 2004
Background The phylogenetic relationships among the holoparasites of Rafflesiales have remained enigmatic for over a century. Recent molecular phylogenetic studies using the mitochondrial matR gene placed Rafflesia, Rhizanthes and Sapria (Rafflesiaceae s.

Phylogeny of the core Malvales: evidence from ndhF sequence data [PDF]

open access: yesAmerican Journal of Botany, 1999
The monophyly of the group comprising the core malvalean families, Bombacaceae, Malvaceae, Sterculiaceae, and Tiliaceae, was recently confirmed by molecular studies, but the internal structure of this clade is poorly understood. In this study, we examined sequences of the chloroplast ndhF gene (aligned length 2226 bp) from 70 exemplars representing 35 ...

24 million years of pollination interaction between European linden flowers and bumble bees

open access: yesNew Phytologist, Volume 248, Issue 4, Page 2111-2127, November 2025.
Summary Pollination is the most common insect–plant mutualism, binding them in a co‐evolutionary framework. Historic evidence of this interaction can be partly inferred from time‐calibrated molecular phylogenies of plant and insect lineages or directly from fossils.
