A deep learning‐enabled toolkit for the 3D segmentation of ventricular cardiomyocytes

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend 3D cardiomyocyte segmentation enables comprehensive analyses of myocardial microstructure in health and disease; however, it is technically demanding. We present an open‐source toolkit for this task, which reduces challenges associated with sample preparation, image restoration, segmentation and proofreading.

Early evolutionary history of the seed

open access: yesBiological Reviews, Volume 101, Issue 3, Page 1511-1553, June 2026.
ABSTRACT The seed is an essential stage in the life history of gymnospermous and angiospermous plants, facilitating both their survival and dispersal. We reappraise knowledge of the evolutionary history of the gymnospermous seed, from its origin in the late Devonian through to the well‐known end‐Permian extinctions – an interval encompassing the ...

Taxonomic Updates of Thismia pseudomelanomitra (Thismiaceae) Reveal an Old Acquaintance From the Ecuadorian Amazon

open access: yesFeddes Repertorium, Volume 137, Issue 2, June 2026.
ABSTRACT The Amazon Basin is home to the world's greatest terrestrial biodiversity, but many plant groups remain poorly studied. One example is the mycoheterotrophic genus Thismia (Thismiaceae), which is notable for its highly specialized floral morphology and ephemeral life cycles, making it difficult to detect in the field and limiting its ...

Genomic Evidence Supports the Recognition of Gentianella waipara Comb. et Stat. nov. as a Distinct Species from G. calcis (Gentianaceae)

open access: yesNew Zealand Journal of Botany, Volume 64, Issue 2, June 2026.
Gentianella calcis subsp. waipara Glenny & Molloy (Gentianaceae) is endemic to limestone formations in North Canterbury, New Zealand. A previous conservation genetics study of G. calcis Glenny & Molloy and another eastern South Island limestone endemic species, G. astonii (Petrie) T.N.Ho & S.W.Liu, showed that G. calcis subsp.

Identification of resistance sources and genomic regions regulating spot blotch resistance in Asian bread wheat (Triticum aestivum L.) via genome‐wide association study

open access: yesThe Plant Genome, Volume 19, Issue 2, June 2026.
Abstract Spot blotch (SB), caused by Bipolaris sorokiniana, is a major yield‐limiting disease of wheat (Triticum aestivum L.) in the warm, humid agroclimatic zones of South Asia. The development of resistant cultivars through molecular approaches offers a sustainable strategy for managing this disease.

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

open access: yesNew 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
