Wee1 kinase differentially regulates maize CDKA2;1a and CDKB1;1

open access: yesThe FEBS Journal, EarlyView.
In eukaryotes, Wee1 kinase inhibits the kinase activity of CDK/Cyc complexes through phosphorylation of a conserved residue in the CDK moiety. Wee1 is also present in plants, but has been scarcely studied. We have studied maize Wee1 regulation of CDKA/CycD2;2a or CDKB/CycD2;2a complexes.

Ecology of reintroduced Rocky Mountain bighorn sheep in Dinosaur National Monument La Ecología de Borrego Cimarron de las Montañas Rocosas Reintroducido en el Monumento Nacional de Dinosaurio

open access: yesWildlife Monographs, Volume 223, Issue 1, August 2026.
We synthesized GPS telemetry, genetic, and pathogen data to evaluate metapopulation processes in a reintroduced Rocky Mountain bighorn sheep (Ovis canadensis canadensis) population in Dinosaur National Monument. We estimated subpopulation‐specific abundances and found 4 small subpopulations with high genetic diversity, partial connectivity, and ...

The potential of seedbank digital information in plant conservation

open access: yesPLANTS, PEOPLE, PLANET, Volume 8, Issue 4, Page 1017-1028, July 2026.
Seedbanks are vital for biodiversity conservation, but their potential remains underutilised due to a limited understanding of the intraspecific genetic diversity they hold. By leveraging digitised data associated with seedbank collections, such as sampling locations, number of maternal plants and seed traits, we can attempt the estimation of genetic ...

Three closely linked X‐chromosomal genes potentially control sex determination in Cannabis sativa

open access: yesNew Phytologist, Volume 251, Issue 1, Page 505-522, July 2026.
Summary Sex determination mechanisms in dioecious plants remain poorly understood yet offer an excellent model system to study genetic changes underlying morphological evolution. We investigated the genetic basis of sex determination in Cannabis sativa, combining quantitative trait locus mapping in a segregating population, comparative transcriptomics ...

Bioconversion of carotenoids into high‐value crocins using a marine sponge carotenoid cleavage dioxygenase

open access: yesNew Phytologist, Volume 250, Issue 5, Page 3230-3246, June 2026.
Summary Carotenoids and apocarotenoids are widespread specialized metabolites, yet animals, including sponges, lack the ability to synthesize carotenoids de novo and must obtain them from dietary or microbial sources. The roles of carotenoid cleavage dioxygenases (CCDs) in marine animals remain largely unexplored. A CCD from the marine sponge Suberites

Canalized to heat, plastic to cold: adaptive coordination of leaf and seed strategies in populations spanning an elevational gradient

open access: yesNew Phytologist, Volume 250, Issue 2, Page 873-884, April 2026.
Summary In tropical mountains, surviving temperature extremes demands finely tuned strategies. We investigated how populations of the bromeliad Pitcairnia flammea across a 2200 m elevational gradient balance genetic canalization and plasticity, and whether thermal strategies are coordinated between seeds and leaves.

Amphibians' Expansion to Record Elevations Influences Chytrid (Batrachochytrium dendrobatidis) Infection Dynamics

open access: yesBiotropica, Volume 58, Issue 2, March 2026.
Peruvian frogs underwent a climate‐driven range expansion into deglaciating mountains, exposing themselves and their fungal pathogen Batrachochytrium dendrobatidis (Bd) to challenging new thermal environments. Bd has dispersed extensively in these new habitats, and elevation may mediate the apparent sublethal impacts of infection for frogs.
