Abstract The ability of plants to successfully regenerate depends on complex physiological and ecological processes, one the first vital stages is seed germination, which temperature, light water availability. Within species variation in germination allows differential responses when facing stimuli key for adaptation natural world. There has been abundant research about temperature changes, but much less known availability, specifically limits potential within a single wild species. Under ongoing climate change with increasing drought episodes it know minimum amount required as well if therefore adapt exists We focused carnation ( Dianthus langeanus ) endemic northwestern Iberian Peninsula. collected seeds from 18 different subpopulations, some only 10 m apart, contrasting microclimatic conditions due topography, slope orientation. measured stress using polyethylene glycol (PEG) solutions, polymer that increases density mimic intensities. found considerable differences under between each subpopulation. Seeds warmer drier subpopulations were able germinate higher stress, meaning their was more tolerant. Our results highlight importance Variation appears be important even at small scales, suggesting an previously unknown future conditions. Read free Plain Language Summary this article Journal blog.

Societal Impact Statement Biodiversity is essential to food security and nutrition locally globally. By reviewing the global state of edible plants highlighting key neglected underutilized species (NUS), we attempt unlock plant resources explore role fungi, which along with wealth traditional knowledge about their uses practices, could help support sustainable agriculture while ensuring better protection environment continued delivery its ecosystem services. This work will inform a wide range user communities, including scientists, conservation development organizations, policymakers, public importance biodiversity beyond mainstream crops. Summary As world's population increasing, humanity facing both shortages (hunger) excesses (obesity) calorie nutrient intakes. fundamental addressing this double challenge, involves far understanding resources. Current estimates suggest that there are at least 7,039 species, in broad taxonomic sense, includes 7,014 vascular plants. striking contrast small handful crops provide majority humanity's intake. Most these have additional uses, most common being medicines (70%), materials (59%), environmental (40%). Species major display centers diversity, as previously proposed, rest follow latitudinal distribution patterns similarly total higher richness lower latitudes. The International Union for Conservation Nature Red List assessments 30% plants, ca. 86% them conserved ex situ. However, 11% those recorded threatened. We highlight multipurpose NUS from different regions world, be more resilient, sustainable, biodiverse, community participation‐driven new “green revolution.” Furthermore, how fungi diversify increase nutritional value our diets.

Summary Assumptions about the germination ecology of alpine plants are presently based on individual species and local studies. A current challenge is to synthesise, at global level, seed ecological spectrum. We performed a meta‐analysis primary data from laboratory experiments conducted across four continents (excluding tropics) 661 species, estimate influence six environmental cues proportion, mean time synchrony; accounting for morphology (mass, embryo : ratio) phylogeny. Most show physiological dormancy, strong need cold stratification, warm‐cued positive responses light alternating temperatures. Species restricted belt have higher preference warm temperatures stronger response stratification than whose distribution extends also below treeline. Seed mass, size phylogeny constraining effects environment. Globally, overwintering key drivers in habitats. The interplay between physiology morphological traits further reflects pressures avoid frost or drought stress. Our results indicate convergence, patterns species.

Plants are not just passive living beings that exist in nature. They complex and highly adaptable species react sensitively to environmental forces/stimuli with movement, morphological changes through the communication via volatile molecules. In a way, plants mimic some traits of animal human behaviour; they compete for limited resources by gaining more area sunlight spread their roots underground. Furthermore, order survive thrive, evolve 'learn' control various stress factors increase yield flowering, fertilization germination processes. The concept associating behaviour, such as intelligence, is still debatable topic among researchers worldwide. Recent studies have shown able discriminate between positive negative experiences from them. Some botanists interpreted these behavioural data form primitive cognitive Others evaluated responses biological automatisms determined adaptation environment absence intelligence. This review aims explore adaptive aspects plant distributed different ecosystems emphasizing complexity survival instincts.

Societal Impact Statement 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 maternal plants and seed traits, we can attempt estimation variation identify gaps in enabling better prioritisation species conservation efforts. These advancements inform policy targets like those Kunming‐Montreal Global Biodiversity Framework, promoting more effective strategies. Digitisation emerging machine‐learning technologies offer scalable, cost‐efficient solutions enhance knowledge, ensuring resilience future generations. Summary Seedbank collections hold significant untapped advancing science practice, (i.e. within species) stored worldwide largely unknown, hindering use seeds both informing implementing situ interventions. As producing is time‐consuming expensive, other greatly our when unavailable. Information location sites, estimated population size mother from which were collected facilitate captured collections.
