First steps towards a floral structural characterization of the major rosid subclades [PDF]

, 2018
A survey of our own comparative studies on several larger clades of rosids and over 1400 original publications on rosid flowers shows that floral structural features support to various degrees the supraordinal relationships in rosids proposed by ...

Extrapolating demography with climate, proximity and phylogeny: approach with caution [PDF]

, 2016
Plant population responses are key to understanding the effects of threats such as climate change and invasions. However, we lack demographic data for most species, and the data we have are often geographically aggregated.

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

Synorganisation without organ fusion in the flowers of Geranium robertianum (Geraniaceae) and its not so trivial obdiplostemony [PDF]

, 2017
Background and Aims Synorganisation of floral organs, an important means in angiosperm flower evolution, is mostly realized by congenital or post-genital organ fusion.

Comparative Genomics Insights Into the Evolutionary Disparities Between Nitroplast‐Evolved Ecotype UCYN‐A2 and Its Closest Relative UCYN‐A1

Ecology and Evolution, Volume 15, Issue 7, July 2025.
This paper conducted comparative genomic analyses among seven UCYN‐A strains in genome content, gene structure, and key metabolic protein genes. In general, our results demonstrated considerable disparities between UCYN‐A1 and UCYN‐A2, providing insights into the evolution of UCYN‐A and nitroplast.

Early eudicot reproductive structure: Fruit and flower morphology of Ranunculaecarpus Samyl. from the Early Cretaceous of eastern Siberia

Acta Palaeobotanica, 2018
Floral and fruit morphology of the early eudicot Ranunculaecarpus quinquecarpellatus Samyl. is described based on details from sectioning and microscopy of the permineralized type material from the Albian Buor-Kemyus Formation of the Zyryanka coal basin.

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

The 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 ...

Diversification of the stem vascular system in a clade of recent radiation and multiple habit transitions: The Bunchosia clade (Malpighiaceae)

American Journal of Botany, Volume 112, Issue 6, June 2025.
Abstract Premise Within the Malpighiaceae, the Bunchosia clade is distinctive for its significant habit variation and abundance of different vascular variants. However, the processes underlying the diversification of the vascular system over time and the ontogenetic events involved remain unclear.
