Trimerous magnoliid flowers with a unique set of floral and pollen traits from the Late Cretaceous of Southern Bohemia (Czech Republic)

New Phytologist, Volume 251, Issue 4, Page 2266-2283, August 2026.
Morphospace position and phylogenetic placements of Trimeriantha monopolyada. Summary Floral structure is a key aspect of angiosperm diversity. Recent research revealed that significant floral disparity was already present in the Cretaceous. However, our understanding of early floral diversity remains limited, as it is directly dependent on the fossil ...

Pollen longevity and viability dataset: an integrated resource for plant research and conservation

New Phytologist, Volume 251, Issue 4, Page 1631-1639, August 2026.
The most common methods to estimate pollen viability. Summary Pollen viability and longevity are key traits in plant reproduction, with implications for gene flow, crop breeding, and ex situ plant conservation. However, published data on these traits remain dispersed across disciplines, languages, and methods, limiting their accessibility and reuse ...

Silene, a versatile model system: from sex and genome evolution to ecology and speciation

New Phytologist, Volume 250, Issue 6, Page 3613-3630, June 2026.
Summary Fundamental and applied research in evolutionary biology benefits from the use of model systems in which approaches from disparate disciplines can be integrated. Here, we review recent progress in evolutionary research on the long‐standing model system Silene, a large genus with a well‐resolved phylogeny and newly available, expanded genomic ...

The abundance of pollen coat small signaling proteins shows limited convergence between independent selfing transitions in Arabidopsis and Capsella

New Phytologist, Volume 250, Issue 5, Page 3460-3474, June 2026.
Summary In plants, a key example of convergence is the repeated evolution of floral traits associated with the transition from outcrossing to self‐fertilization, often resulting in the ‘selfing syndrome’ (e.g. reduced flower size and loss of scent). However, potentially overlooked changes concern the pollen coat, which plays a role in different aspects

Hybridity of mainly asexually propagating duckweeds in genus Lemna – dead end or breakthrough?

New Phytologist, Volume 250, Issue 1, Page 629-647, April 2026.
Summary The cosmopolitan, mainly vegetatively propagating, organ‐reduced monocotyledonous aquatic duckweeds are the smallest and fastest growing angiosperms, distributed world‐wide and flower rarely in nature. Recently, we reported intra‐ and interspecific hybrids and ploidy variants in the genus Lemna.
