General volatile anesthetic diethyl ether blocks sensation and responsive behavior not only in animals but also plants. Here, using a combination of RNA-seq proteomic LC-MS/MS analyses, we investigated the effect on gene expression downstream consequences plant Arabidopsis thaliana. Differential analyses revealed reprogramming under anesthesia: 6,168 genes were upregulated, 6,310 downregulated, while 9,914 affected comparison with control On protein level, out 5,150 proteins identified, 393 significantly upregulated 227 downregulated. Among highest downregulated processes etherized plants chlorophyll/tetrapyrrole biosynthesis photosynthesis. However, measurements chlorophyll fluorescence did show inhibition electron transport through photosystem II. The most process was response to heat stress (mainly shock proteins, HSPs). Using transgenic A. thaliana expressing APOAEQUORIN, showed transient increase cytoplasmic calcium level [Ca2+]cyt application. In addition, cell membrane permeability for ions increased anesthesia. pre-treated ether, thus induced HSPs, had tolerance II subsequent known as cross-tolerance or priming. All these data indicate that anesthesia may partially mimic plasma membrane.

Salt stress severely limits the productivity of crop plants worldwide and its detrimental effects are aggravated by climate change. Due to a significant world population growth, agriculture has expanded marginal salinized regions, which usually render low yield. In this context, finding methods strategies improve plant tolerance against salt is utmost importance fulfill food security challenges under scenario ever-increasing human population. Plant priming, at different stages development, such as seed or seedling, gained attention for marked implication in salt-stress management. It promising field relying on applications specific chemical agents could effectively tolerance. Currently, variety chemicals, both inorganic organic, can efficiently promote growth yield available market.

Climate change-induced extreme weather events (heat, cold, drought, and flooding) will severely affect crop production. Increasing the resilience of crops to fluctuating environmental conditions is critically important. Here, we report that nanomaterials (NMs) with reactive oxygen species (ROS)-generating properties can be used as seed priming agents simultaneously enhance tolerance maize seeds seedlings diverse even multiple stresses. Maize primed 40 mg/L silver nanoparticles (AgNPs) exhibited accelerated germination an increased rate, greater seedling vigor, better growth under drought (10% 20% PEG), saline (50 100 mM NaCl), cold (15 °C) stress conditions, indicating enhanced Importantly, resistance simultaneous stresses (drought salt, salt cold) was markedly enhanced. Under significantly boosted root hair density length (17.3–82.7%), which enabled water deficiency. RNA-seq analysis reveals AgNPs induced a transcriptomic shift in seeds. Plant hormone signal transduction MAPK signaling pathways were activated upon priming. low-cost environmentally friendly ROS-generating Fe-based NMs (Fe2O3 Fe3O4 NPs) also demonstrated These findings demonstrate simple strategy climate through modulated ROS homeostasis this approach could powerful nanoenabled tool for addressing worsening food insecurity.

Abstract The plant genome exhibits a significant amount of transcriptional activity, with most the resulting transcripts lacking protein-coding potential. Non-coding RNAs play pivotal role in development and regulatory processes plants. Long non-coding (lncRNAs), which exceed 200 nucleotides, may enhancing resilience to various abiotic stresses, such as excessive heat, drought, cold, salinity. In addition, exogenous application chemicals, abscisic acid salicylic acid, can augment defense responses against stress. While how lncRNAs stress tolerance is relatively well-studied model plants, this review provides comprehensive overview current understanding function horticultural crop It also delves into potential chemical priming plants order acquire tolerance, although many limitations exist proving lncRNA functionality under conditions.

Abstract For survival in the natural environment, plants have evolved a ‘bet-hedging’ strategy where individual variation is high and range of phenotypes produced. When faced with unpredictable environmental conditions, fluctuation seed behaviour beneficial trait that allows plant species to survive, particularly if seedlings from early-germinated seeds die. However, this not desired an agricultural perspective, set uniformly growing required. Whilst variability unavoidable, over centuries humans attempted select minimum for use. In model Arabidopsis, even non-stratified same silique germinate variably, it remains elusive how manifested genes physiological outcome what molecular mechanisms bet-hedging facilitate diversity. Will re-introduction valuable wild alleles into domesticated crops contribute between by promoting bet-hedging? Recent advances shed light on possible pathways germination are affected at level single cells. Here, we review hormonal, molecular, cellular might affect genetically identical seeds.
