Evolutionary legacy of the “living fossil” genus Parrotia (Hamamelidaceae): genomic insights into species divergence and polygenic adaptation

open access: yesThe Plant Journal, Volume 123, Issue 2, July 2025.
Significance Statement Parrotia is a Tertiary relict “living fossil” tree genus with two extant species (P. subaequalis and P. persica) exhibiting a disjunct distribution between East Asia and West Asia. Despite their long evolutionary history, the genomic basis of adaptation and speciation in this “living fossil” tree genus remain largely unexplored ...

Phylogenetic and biochemical drivers of plant species variation in organic compound hydrogen stable isotopes: novel mechanistic constraints

open access: yesNew Phytologist, Volume 246, Issue 1, Page 113-130, April 2025.
Summary Significant variation in plant organic compound hydrogen stable isotope (δ2H) values among species from a single location suggests species biochemistry diversity as a key driver. However, the biochemical mechanisms and the biological relevance behind this species‐specific δ2H variation remain unclear.

Differential Interpretation of Mountain Temperatures by Endospermic Seeds of Three Endemic Species Impacts the Timing of In Situ Germination

open access: yesPlants, 2020
Predicting seed germination in the field is a critical part of anticipating the impact of climate change on the timing of wild species regeneration. We combined thermal time and soil heat sum models of seed germination for three endemic Mediterranean ...

Suffruticosol B from Paeonia lactiflora Ameliorates Alzheimer's Disease Pathology by Inhibiting MAO‐B Activity

open access: yesPhytotherapy Research, Volume 39, Issue 2, Page 593-603, February 2025.
ABSTRACT Monoamine oxidase B (MAO‐B) has emerged as a therapeutic target for Alzheimer's disease (AD) due to its involvement in the synthesis of γ‐aminobutyric acid (GABA) in reactive astrocytes, which inhibits neuronal activity. Suffruticosol B (Suf‐B), isolated from Paeonia lactiflora, is one of the resveratrol oligomers.
