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.

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 ...

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 Comparative Study on Molecular Phylogenetics and Development of Microsatellite Primers From Durian Chloroplast Genomes

open access: yesEcology and Evolution, Volume 15, Issue 10, October 2025.
Based on the chloroplast genomes, the phylogenetic relationship of durian cultivars was visualized. Furthermore, 13 SSR primer pairs were designed and could be applied for genetic diversity and genotyping studies. ABSTRACT Durian, or Durio zibethinus, is an exotic fruit with high economic value in Southeast Asia.

A Group 6 LEA Protein Plays Key Roles in Tolerance to Water Deficit, and in Maintaining the Glassy State and Longevity of Seeds

open access: yesPlant, Cell &Environment, Volume 48, Issue 9, Page 6874-6896, September 2025.
ABSTRACT Plants have a wide range of adaptive and protective mechanisms to cope with dehydration. Central in these processes are the Late Embryogenesis Abundant (LEA) proteins, whose levels notably increase in response to dehydration during seed development and vegetative tissues.
