Project description:Phosphorus (P) limitation will play a key role in the productivity of agriculture in the coming decades. Struvite is an ammonium magnesium phosphate mineral that can be recovered from wastewater-treatment plants and can be considered as an alternative source of P. However, the impact of struvite on the plant yield and, particularly, on the soil microbial community is barely known. Here, we tested the impacts of struvite, sewage sludge, and their combination on the barley yield, soil macro and micronutrients, and biochemical and microbiological soil properties. Amendment with struvite alone and its combination with sludge increased the availability of P in soil, the plant uptake of P and Mg, and the barley yield. The analysis of phospholipid fatty acids (PLFAs) and metaproteomics approaches revealed significant effects of struvite on the biomass of Gram-positive bacteria and, particularly, on actinobacterial populations in soil.

Project description:The use of biofertilizers is becoming an economical and environmentally friendly alternative to promote sustainable agriculture. Biochar from microalgae can be applied to enhance the productivity of food crops through soil improvement, slow nutrient absorption and release, increased water uptake, and long-term mitigation of greenhouse gas sequestration. Therefore, the aim of this study was to evaluate the stimulatory effects of biochar produced from Spirulina platensis biomass on the development and seed production of rice plants. Biochar was produced by slow pyrolysis at 300°C, and characterization was performed through microscopy, chemical, and structural composition analyses. Molecular and physiological analyses were performed in rice plants submitted to different biochar concentrations (0.02, 0.1, and 0.5 mg mL-1) to assess growth and productivity parameters. Morphological and physicochemical characterization revealed a heterogeneous morphology and the presence of K and Mg minerals in the biochar composition. Chemical modification of compounds post-pyrolysis and a highly porous structure with micropores were observed. Rice plants submitted to 0.5 mg mL-1 of biochar presented a decrease in root length, followed by an increase in root dry weight. The same concentration influenced seed production, with an increase of 44% in the number of seeds per plant, 17% in the percentage of full seeds per plant, 12% in the weight of 1,000 full seeds, 53% in the seed weight per plant, and 12% in grain area. Differential proteomic analyses in shoots and roots of rice plants submitted to 0.5 mg mL-1 of biochar for 20 days revealed a fine-tuning of resource allocation towards seed production. These results suggest that biochar derived from Spirulina platensis biomass can stimulate rice seed production.

Project description:Composts are the products obtained after the aerobic degradation of different types of organic matter wastes and can be used as substrates or substrate/soil amendments. There are a small but increasing number of reports that suggest that foliar diseases may be reduced when using compost as growing medium compared to standard substrates. The purpose of this study was to unravel the gene expression alteration produced by the compost to gain knowledge about the mechanisms involved in the compost-induced systemic resistance. A compost from olive marc and olive tree leaves was able to induce resistance against Botrytis cinerea in Arabidopsis compared to the standard substrate perlite. Microarray analyses revealed that 178 genes were differently expressed with a fold change cut off of 1 from which 155 were upregulated and 23 were down regulated in compost-grown compared to perlite-grown plants. Functional enrichment study of up regulated genes revealed that 38 Gene Ontology terms were significantly enriched. Response to stress, biotic stimulus, other organism, bacterium, fungus, chemical and abiotic stimulus, SA and ABA stimulus, oxidative stress, water, temperature and cold were significantly enriched terms as well as immune and defense responses, systemic acquired resistance, secondary metabolic process and oxireductase activity. Interestingly, PR1 expression, which was equally enhanced by growing the plants in compost and by B. cinerea inoculation, was further boosted in compost-grown pathogen-inoculated plants. Compost triggered a plant response that shares similarities with both systemic acquired resistance and ABA dependent/independent abiotic stress responses.

Project description:In this work, we used a functional gene microarray approach (GeoChip) to assess the soil microbial community functional potential related to the different wine quality. In order to minimize the soil variability, this work was conducted at a “within-vineyard” scale, comparing two similar soils (BRO11 and BRO12) previously identified with respect to pedological and hydrological properties within a single vineyard in Central Tuscany and that yielded highly contrasting wine quality upon cultivation of the same Sangiovese cultivar

Project description:There is inadequate understanding of the environmental fate and effects of engineered nanoparticles, including nanoceria. Also, knowledge about the influence of environmental factors on the bioavailability of these particles and resulting impacts on the nutritional quality of crops is limited. Alterations in mineral and macromolecular composition of some grains and fruits under nanoceria exposure have been reported recently; however, the cellular mechanisms associated with the effects are unknown. Here, we show that the impact of nanoceria at 62.5 to 500 mg/kg soil on kidney bean (Phaseolus vulgaris) productivity and seed quality are influenced by soil organic matter content. Seeds obtained from plants exposed to nanoceria at 125 mg/kg showed unique and contrasting response in terms of nutritional quality under varying soil organic matter content. Additionally, quantitative proteomic analysis provides evidence for dose-dependent down-regulation of some major proteins associated with nutrient storage and carbohydrate metabolism, including phaseolin and lectins in the exposed seeds. This study suggests that nCeO2 exposure negatively impacts the nutritional quality of kidney beans. This altered seed quality may have significant implications for food production and human health.

Project description:rs11-07_opine2 - septante soil - Transcriptomic changes induced by opine production in Arabidopsis thaliana grown in natural soil - Arabidopsis thalian Col- line was transformed in order to obtain transgenic lines that produce opine compound (octopine and mannopine). Transgenic lines producing respectively octopine and mannopine and the WT line were grown in greenhouse under long-day condition in pots containing half commercial compost and half soil of la Mérantaise and watered with water. Whole plant aged of one month were harvested and frozen in liquid nitrogen. The plants were ground with a mortar an pestls and RNA extraction was performed with the RNeasy extraction kit (QIAGEN) with cristal of PVP. The RNA concentration was measured on a NANODrop spectrophotometer.
