Project description:Plant nutrition takes advantage by the simultaneous presence of more N forms in the rhizosphere. In the last decades the interplay between ammonium and nitrate acquisition systems in roots has been deeply investigated. Although widely used as fertilizers, the occurrence of cross connection between urea and ammonium nutrition has been scarcely studied in plants, especially at molecular level. In a recent paper we provided evidence that maize plants fed with urea and ammonium mix showed a better N-uptake efficiency than plants fed with ammonium or urea alone. To elucidate the molecular mechanism underlying this response, transcriptomic and metabolomic changes occurring in maize plants were investigated. Transcriptomic analyses indicated that several transporters and enzymes involved in N-nutrition were found upregulated by all three N-treatments (AMT1.3, NRT1.1, NRT2.1, GS1, GOGAT, GDH), confirming that urea is a direct source of N for plants. Depending on N-form available in nutrient solution a peculiar response at transcriptomic and metabolomic level was observed, especially after 24 hours of treatment. In comparison to one single N-form, urea and ammonium mix induced a prompt assimilation of N, characterized by an overaccumulation of main amino acids in shoots, and an upregulation of ZmAMT1.1. Moreover even a peculiar modulation of aquaporins, carbonic anydrases, glutamine synthetase, amino aspartate, as well as the glycolysis-TCA cycle was induced in roots by urea and ammonium mix. Depending on N-form available in the external media, even changes in phytohormone’s composition were observed in maize (CKs, ABA, JA); in particular, already after 24 hours of treatment, urea induced the accumulation of trans-zeatin in shoots. Through a multiomics approach, we provide for the first time molecular characterization of maize response to urea and ammonium nutrition. This study paves the way to formulate guidelines for the optimization of N fertilization of crops to improve the N use efficiency in plants and therefore limit N losses in the environment.

Project description:In the soil the stability of urea is affected by the presence of urease, a ubiquitous enzyme released in the rhizosphere by microbial population and by decomposition of organic matter. To reduce the impact on farmer economies and environmental pollution, a common agronomical practice consists of applying urease inhibitors which delays the hydrolysis of urea and, in turn, ammonia is slowly release in the soil. General aim of the present work was the description of changes in maize root transcriptome occurring in response to treatment with the urease inhibitor NBPT.

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:The goal of the present project was to investigate the applicability of a triple extraction (”TE”), which yields RNA, DNA and protein in a single procedure, for gel-free mass spectrometry-based proteomics. Proven successful for large-scale transcriptomics and genomics, we examined TE compatibility with mass spectrometry-based proteomics and phospho-proteomics by comparison to a urea standard processing. For whole proteome, peptides were fractionated using SAX; for phosphorylation analysis, modifications were enriched using TiO2 columns. We here demonstrate the efficiency of TE protocol for shotgun proteomics, providing similar results as urea-derived samples both at the qualitative and quantitative levels. The study of phosphorylation events is likewise compatible with TE, which actually results in a higher number of correctly localized sites than urea, while the nature of extracted sites appears somewhat distinct between both techniques. We thus conclude that our protocol is well suited for proteomics and as efficient as other more widely used workflows for mass spectrometry-based analysis.
