Early evolutionary history of the seed

Biological 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 ...

Lactate metabolism and lactylation in female reproductive diseases: From metabolic rewiring to biomarkers and translational therapeutics

Clinical and Translational Medicine, Volume 16, Issue 6, June 2026.
1. Lactate‐derived histone lactylation links glycolytic reprogramming to epigenetic regulation in female reproductive diseases. 2. In endometriosis, lactylation may promote inflammatory remodelling, immune dysregulation and ferroptosis resistance. 3. In PCOS, lactylation connects metabolic disturbance to granulosa‐cell dysfunction and hyperandrogenism.

Generation and Characterization of Twist1 Acetyl‐Mimic and Acetyl‐Deficient Mouse Models

genesis, Volume 64, Issue 3, June 2026.
ABSTRACT TWIST1 encodes a highly conserved basic helix–loop–helix transcription factor essential for embryonic development from Drosophila to humans. TWIST1 activity is regulated by post‐translational modifications, including phosphorylation during development and cancer metastasis. Recent cancer studies identified acetylation of lysines K73 and K76 as

Competent Non‐Native Alternative Host Reduces Infection Success in a Generalist Parasite

Ecology and Evolution, Volume 16, Issue 6, June 2026.
In this study, we experimentally assessed how the addition of a non‐native alternative host affects the infection success of the larval generalist trematode, Diplostomum pseudospathaceum, in fish intermediate hosts. Our results demonstrate that the presence of alternative hosts, especially the non‐native ones, can reduce parasite transmission through ...

Combining individual and close‐kin mark–recapture to design an effective wildlife population survey

Ecology, Volume 107, Issue 6, June 2026.
Abstract Close‐kin mark–recapture (CKMR) is a promising approach for assessing population size of species that have been difficult to survey using more traditional methods. Here, we combine individual and close‐kin mark–recapture in a single modeling framework (ICKMR) and provide an example of study design using this approach for Pacific walrus ...
