The study projects the future bioclimatic suitability of 35 invasive non‑native plant species across the Pyrenees using ensemble species‑distribution models under four climate scenarios up to 2100. Results suggest that most species will not expand climatically, with suitable habitats shifting upslope and concentrating around 2,000 m, thereby limiting overlap with endemic flora. The authors argue that these projections can help prioritize monitoring and early‑intervention strategies in mountain ecosystems.

The study examined how rising Arctic temperatures affect flowering phenology in the Arctic‑alpine plant Oxyria digyna by analyzing approximately 120 years of herbarium specimens alongside climate data. Linear regression analyses revealed that Boreal Arctic populations advanced flowering with increased summer and June temperatures, whereas Alpine and Arctic Tundra populations showed different timing shifts linked to June temperature changes. These findings highlight variable adaptive potential among populations in response to rapid climatic warming.

The study investigates how elevated temperatures associated with climate change affect NLR-mediated immunity, focusing on the Arabidopsis RPS4/RRS1 pair that confers resistance to Ralstonia pseudosolanacearum. By integrating natural genetic variation screening, genetic mapping, polymorphism analysis, structural modeling, and functional complementation, the authors identified a specific RPS4/RRS1 haplotype whose leucine-rich repeat substitutions compromise thermostable resistance. These results suggest that leveraging natural diversity can enable the engineering of climate‑resilient disease resistance.

The authors used a bottom‑up thermodynamic modelling framework to investigate how plants decode calcium signals, starting from Ca2+ binding to EF‑hand proteins and extending to higher‑order decoding modules. They identified six universal Ca2+-decoding modules that can explain variations in calcium sensitivity among kinases and provide a theoretical basis for interpreting calcium signal amplitude and frequency in plant cells.

The study examines how ectopic accumulation of methionine in Arabidopsis thaliana leaves, driven by a deregulated AtCGS transgene under a seed‑specific promoter, reshapes metabolism, gene expression, and DNA methylation. High‑methionine lines exhibit increased amino acids and sugars, activation of stress‑hormone pathways, and reduced expression of DNA methyltransferases, while low‑methionine lines show heightened non‑CG methylation without major transcriptional changes. Integrated transcriptomic and methylomic analyses reveal a feedback loop linking sulfur‑carbon metabolism, stress adaptation, and epigenetic regulation.

In a two-year controlled-environment experiment, diploid and tetraploid individuals of wild-type and cultivar Marshall annual ryegrass (Lolium multiflorum) were grown under elevated CO2 (540 vs 800 ppm) and differing evapotranspiration regimes. Elevated CO2 increased total biomass by 44% across ploidy levels, and tetraploid wild-type plants matched the improved cultivar in growth and forage quality, indicating that chromosome manipulation and wild genetic resources can enhance climate resilience.

The study examined how polyploidy, hybridization, and incomplete lineage sorting affect phylogenetic reconstructions in the genus Packera, evaluating several published paralog‑processing pipelines. Results showed that the choice of orthology and paralog handling methods markedly altered tree topology, time‑calibrated phylogenies, biogeographic histories, and detection of ancient reticulation, underscoring the need for careful methodological selection alongside comprehensive taxon sampling.

The study combined hyperspectral reflectance, inverse PROSPECT modeling, and network analysis to evaluate functional leaf trait variation and detect local adaptation in four Streptanthus tortuosus populations grown in a common garden. High classification accuracy revealed heritable spectral signatures associated with anthocyanins, carotenoids, chlorophyll, and water content, while trait‑climate relationships and spectral network modularity shifted between historical and recent climate periods, indicating evolutionary responses in coordinated trait networks.

The study employed a portable near‑infrared spectrometer to longitudinally monitor sugar and acid dynamics in individual berries of ten grapevine varieties over two seasons, calibrating the spectra against HPLC measurements using partial least squares regression. The resulting models accurately predicted glucose, fructose, and malic acid levels, revealing that single berries ripen about twice as fast as aggregates, highlighting a precise quantitative approach for assessing berry ripening under climate change.

The study evaluated the combined effects of elevated CO₂, temperature, and water availability on Lactuca sativa grown in controlled indoor chambers over 21 days, measuring biomass, mortality, and leaf nitrogen. Elevated CO₂ generally enhanced growth and survival, but high temperature and extreme water conditions reduced both, indicating that climate‑induced CO₂ increases may not offset heat and water stress on lettuce yield.
