Plant-Derived Smoke Affects Biochemical Mechanism on Plant Growth and Seed Germination.

ABSTRACT: The role of plant-derived smoke, which is changed in mineral-nutrient status, in enhancing germination and post-germination was effectively established. The majority of plant species positively respond to plant-derived smoke in the enhancement of seed germination and plant growth. The stimulatory effect of plant-derived smoke on normally growing and stressed plants may help to reduce economic and human resources, which validates its candidature as a biostimulant. Plant-derived smoke potentially facilitates the early harvest and increases crop productivity. Karrikins and cyanohydrin are the active compound in plant-derived smoke. In this review, data from the latest research explaining the effect of plant-derived smoke on morphological, physiological, biochemical, and molecular responses of plants are presented. The pathway for reception and interaction of compounds of plant-derived smoke at the cellular and molecular level of plant is described and discussed.

Project description:Non-thermal plasma holds great potentials as an efficient, economical, and eco-friendly seed pretreatment method for improving the seed germination and seedling growth, but the mechanisms are still unclear. Therefore, a plant model organism Arabidopsis thaliana was used to investigate the physio-biochemical responses of seeds to non-thermal plasma at different treatment times by measuring the plant growth parameters, redox-related parameters, calcium (Ca2+) level and physicochemical modification of seed surface. The results showed that short-time plasma treatment (0.5, 1, and 3 min) promoted seed germination and seedling growth, whereas long-time plasma treatment (5 and 10 min) exhibited inhibitory effects. The level of superoxide anion (O2 •-) and nitric oxide (NO) and the intensity of infrared absorption of the hydroxyl group were significantly higher in short-time plasma treated Arabidopsis seeds, and the level of hydrogen peroxide (H2O2) was remarkably increased in long-time plasma treated seeds, indicating that O2 •-, ·OH, and NO induced by plasma may contribute to breaking seed dormancy and advancing seed germination in Arabidopsis, while plasma-induced H2O2 may inhibit the seed germination. The intensity of hydroxyl group and the contents of H2O2, malondialdehyde, and Ca2+ in Arabidopsis seedlings were obviously increased with the plasma treatment time. Catalase, superoxide dismutase, and peroxidase activities as well as proline level in short-time treated seedlings were apparently higher than in control. The etching effects of plasma on seed surface were dose-dependent, spanning from slight shrinkages to detached epidermis, which also significantly increased the oxidation degree of seed surface. Therefore, the improved activities of antioxidant systems, moderate ·OH, H2O2, and Ca2+ accumulation and seed surface modification induced by plasma all contribute to the enhanced seedling growth of Arabidopsis after short-time plasma treatment.

Project description:Sensing environmental cues is essential for plants in order to respond properly to, adapt to and survive changes in the environment and disturbances. Smoke-derived germination active compounds are important cues which provide a strong chemical signal to seeds in the soil seed bank about the available germination niche created by the passage of fire. The germination stimulatory activity can largely be attributed to the presence of the butenolide, 3-methyl-2H-furo[2,3-c]pyran-2-one (karrikinolide; KAR1). More recently, a related fire-borne butenolide, 3,4,5-trimethylfuran-2(5H)-one (inhibenolide A; InhA), was shown to have an inhibitory effect on germination. The aim of this study was to extensively characterize the interaction of these potent smoke-derived compounds in the highly KAR1-sensitive Lactuca sativa cv. M-bM-^@M-^XGrand RapidsM-bM-^@M-^Y achenes. A time course microarray analysis of KAR1- and InhA-treated achenes was performed using custom-made Agilent microarrays. Early time points for sampling the transcriptome were chosen by taking into account the fact that treatment with KAR1 is irreversible (by leaching with water) after 2 h, and that the KAR1-treated achenes enter an InhA-insensitive stage after 9 h. Therefore, samples were harvested after 2 and 10 h of initial exposure to 0.1 M-BM-5M KAR1 or 10 M-BM-5M InhA, and after 24 h, when germinated and non-germinating achenes could be distinguished visually. To assess the divergence between the expression patterns induced by the two compounds, a sample of achenes treated with 0.1 M-BM-5M KAR1 and 10 M-BM-5M InhA simultaneously, was harvested after 2 h. At 24 h, samples were collected from germinating and non-germinating achenes separately, and equal amounts of mRNA were pooled. Although this design implies that there is a small chance of losing data, our primary aim at 24 h was to screen for differences between the KAR1- and InhA-induced transcriptome. Achenes germinated in distilled water served as controls and were compared to the experimental samples treated as described above.

Project description:Multicomponent materials, where nanosized selenium (Se) is dispersed in polymer matrices, present as polymer nanocomposites (NCs), namely, selenium polymer nanocomposites (SeNCs). Selenium as an inorganic nanofiller in NCs has been extensively studied for its biological activity. More ecologically safe and beneficial approaches to obtain Se-based products are the current challenge. Biopolymers have attained great attention with perspective multifunctional and high-performance NCs exhibiting low environmental impact with unique properties, being abundantly available, renewable, and eco-friendly. Composites based on polysaccharides, including beta-glucans from edible and medicinal mushrooms, are bioactive, biocompatible, biodegradable, and have exhibited innovative potential. We synthesized SeNCs on the basis of the extracellular polysaccharides of several medicinal mushrooms. The influence of bio-composites from mushrooms on potato plant growth and tuber germination were studied in two potato cultivars: Lukyanovsky and Lugovskoi. Bio-composites based on Grifola umbellata demonstrated the strongest positive effect on the number of leaves and plant height in both cultivars, without negative effect on biomass of the vegetative part. Treatment of the potato tubers with SeNC from Gr. umbellata also significantly increased germ length. Potato plants exposed to Se-bio-composite from Ganoderma lucidum SIE1303 experienced an increase in the potato vegetative biomass by up to 55% versus the control. We found earlier that this bio-composite was the most efficient against biofilm formation by the potato ring rot causative agent Clavibacter sepedonicus (Cms). Bio-composites based on Pleurotus ostreatus promoted increase in the potato root biomass in the Lugovskoi cultivar by up to 79% versus the control. The phytostimulating ability of mushroom-based Se-containing bio-composites, together with their anti-phytopathogenic activity, testifies in favor of the bifunctional mode of action of these Se-biopreparations. The application of stimulatory green SeNCs for growth enhancement could be used to increase crop yield. Thus, by combining myco-nanotechnology with the intrinsic biological activity of selenium, an unexpectedly efficient tool for possible applications of SeNCs could be identified.
