Summary Extreme temperatures surpassing 45°C can cause widespread plant damage and mortality, with severe consequences for ecosystem health, agricultural productivity, urban greenery, thus negatively impacting human well‐being. The global land area experiencing regular heatwaves is increasing, this trend expected to continue the foreseeable future. Despite alarming scenario, molecular mechanisms underlying thermotolerance responses extreme heat‐induced are not fully understood. As cells basic building blocks of plant, studies at cellular level required elucidate fine‐tuned signaling pathways regulating cell death survival under high heat stress, thereby generating knowledge needed better understand temperature whole level. Well‐established model systems that allow accurate measurement quantification stress‐induced programmed have a strong potential enable multifactorial studies, including use regimes informed by natural settings combinatorial stress experiments. gained as result inform development effective mitigation strategies. Studying how cope aligned One Health approach, several United Nations Sustainable Development Goals, is, therefore, research demands urgent attention.

Self-pollination in self-compatible plant species often occurs prior to flower opening. By tracking the temporal progress of pollination Arabidopsis, we observed that pollen predominantly targets lateral region stigma unopened flowers. Notably, approximately 7 h after opening, flowers close, thereby pressing anthers toward central for a second self-pollination. This two-step self-pollination results doubling deposition, which significantly increases ovule-targeting ratio and improves fertility under pollen-limiting conditions, as evident anther-dehiscence-defective mutant myb108 environmental stress conditions. Analysis using gamete-interaction-defective mutants hap2/gcs1 dmp8 dmp9 revealed timely separation both events promotes fertilization recovery efficiency. A similar was two other self-pollinating but not outcrossing Brassicaceae species. mechanism represents reproductive assurance strategy annuals maximize unfavorable

Climate change is a global problem facing all aspects of the agricultural sector. Heat stress due to increasing atmospheric temperature one most common climate impacts on agriculture. has direct effects crop production, along with indirect through associated problems such as drought, salinity, and pathogenic stresses. Approaches reported be effective mitigate heat include nano-management. Nano-agrochemicals nanofertilizers nanopesticides are emerging approaches that have shown promise against stress, particularly biogenic nano-sources. Nanomaterials favorable for production their low toxicity eco-friendly action. This review focuses different stresses production. Nano-management crops under including application nanopesticides, discussed. The potential limitations these nano-agrochemicals reviewed. Potential nanotoxicity need more investigation at local, national, levels, well additional studies into soil, plant, microbial properties processes.

Abstract Local adaptation may facilitate range expansion during invasions, but the mechanisms promoting destructive invasions remain unclear. Cheatgrass ( Bromus tectorum ), native to Eurasia and Africa, has invaded globally, with particularly severe impacts in western North America. We sequenced 307 genotypes conducted controlled experiments. found that diverse lineages America, where long-distance gene flow is common. Ancestry phenotypic clines predicted those range, indicating pre-adapted colonized different regions. Common gardens showed directional selection on flowering time reversed between warm cold sites, potentially maintaining clines. In Great Basin, genomic predictions of strong local identified sites cheatgrass most dominant. Preventing new introductions fuel critical for managing ongoing invasions.

ABSTRACT Pollen development and germination are critical for successful generation of offspring in plants, yet they highly susceptible to heat stress (HS). However, the molecular mechanism underlying this process has not been fully elucidated. In study, we highlight essential roles two mRNA capping enzymes, named Arabidopsis phosphatase (ARCP) 1 2, regulating male female gamete development. The transmission efficiencies gametes carrying arcp1 arcp2 from +/− −/− mutants 30% zero, respectively. These exhibited a significant increase misshaped pollen, with rates approximately half those wild type. ARCP1/2 exhibit RNA triphosphatase guanylyltransferase activities, which required proper pollen Through RNA‐seq analysis, genes involved development/germination HS response were identified as downregulated mutant. Furthermore, ARCP2 protein is degraded under condition, inducing expression can rate elevated temperature. We propose that triggers degradation turn disrupts transcriptome ultimately leads sterility.

ABSTRACT Climate change is leading to more frequent and severe extreme temperature events, negatively impacting agricultural productivity threatening global food security. Plant reproduction, the process fundamental crop yield, highly susceptible heatwaves, which disrupt pollen development ultimately affect seed‐set yields. Recent research has increasingly focused on understanding how grains from various crops react heat stress at molecular cellular levels. This surge in interest over last decade been driven by advances genomic technologies, such as single‐cell RNA sequencing, holds significant potential for revealing underlying regulatory reprogramming triggered throughout stages of development. review focuses affects gene networks, including response, unfolded protein autophagy, discusses impact these changes It highlights selection a key strategy improving tolerance leveraging genetic variability among grains. Additionally, genome‐wide association studies population screenings have shed light underpinnings traits major that respond high temperatures during male reproductive stages. Gene‐editing tools like CRISPR/Cas systems could facilitate precise modifications boost resilience. The information covered this valuable selecting employing approaches develop heat‐tolerant genotypes.

In the intricate world of plant responses to environmental stress, concept thermomemory has emerged as a fascinating and complex phenomenon. Plants, sessile organisms, continually face challenge adapting fluctuating climates, ability “remember” prior heat stress encounters, phenomenon known is testament their remarkable adaptability. Nitric oxide (NO), versatile signaling molecule in physiology, been implicated myriad cellular processes crucial for adaptation. From its involvement stomatal regulation influence on gene expression antioxidant defense mechanisms, NO emerges central orchestrator plant’s response elevated temperatures. Exploration NO-mediated pathways provides insights into how plants not only cope with immediate but also retain memory these encounters. Unraveling molecular intricacies NO’s enhances our understanding sophisticated strategies employed by navigate changing climate, offering potential avenues innovative approaches enhancing crop resilience sustainable agriculture.
