Abstract:

The RhizoSTIM project aims to develop a multifunctional next-generation plant biostimulant product based on strigolactones mimics. This product will act both as a modulator of the rhizomicrobiome and as a regulator of plant response to stress. Strigolactones (SL) are both in-planta and ex-planta signals. These compounds are plant hormones, endogenous molecules that regulate plant response to stress, ecomones/semiochemicals, and exogenous signals involved in plants communication in the rhizosphere. The project objectives are: (i) to design and to develop new strigolactones mimics acting on rhizosphere microorganisms and on plant internal regulating cascade; (ii) to understand the effect of strigolactones mimics on rhizosphere microorganisms and model plants (iii) to test the strigolactone mimics on model systems. The expected results of the project are: (i) QSAR / SAR analysis of SLs mimics by predicting their biological activity as plant biostimulants, useful to guide the synthesis of the new strigolactone mimics; (ii) new chemically synthesized SL mimics, (iii) selected SL mimics with specific activities on beneficial microorganisms from the rhizosphere, others than AMF fungi, substantiated by (iv) in silico identification of the strigolactones putative receptors from rhizosphere microorganisms; (v) demonstration of strigolactone mimics effects on plant and rhizosphere microorganisms which should substantiate the claims for a (vi) multifunctional next-generation plant biostimulant. The RhizoStim project main novelties are related to: (i) synthesis of SL mimics according to a QSAR / SAR analysis, (putative) fungal receptor identification, and atom economy concept, and (ii) multifunctionality, related to effects on plant internal regulating cascade and to effects on microorganisms from the rhizosphere.

Abstract:

The project addresses mainly the thematic area of Biotechnology, more exactly the key topic Biotechnology for agriculture, aquaculture, forestry and biomass production. The biotechnological solutions which STIM4+ project proposes to develop are intended to compensate the negative effects of the low-input, high-residue sustainable vegetable production systems. These proposed biotechnological solutions are related to the use of the next generation plant biostimulants. Plant biostimulants represent an emerging class of agricultural input, which protect plants against abiotic stress, enhance / benefits nutrients uptake and improve yield quality . The proposed plant biostimulants to be used for an enhanced sustainability of field vegetables grown in a high residue system are including into all classes / subclasses mentioned in the new EU Regulation 1009/2019. The multi-functional Trichoderma strains-based plant biostimulants (a microbial plant biostimulants) will be included into a glycodinameric, chitosan based bioactive (micro)hydrogel formulation. Decoration of microgels with anchor peptides will be used as a (micro)hydrogel tackifier on the plant residues. The bioactive hydrogel is based on an organic plant biostimulants (chitosan), which will be used to generate a biocompatible 3D porous structure, thermo- and pH-responsive and with a hydrophilic – hydrophobic segregation feature. This hydrophilic – hydrophobic segregation (micro)hydrogels will be used for embedding hydrophobic mimetic strigolactones. Propper application technologies of such smart formulated hydrophobic molecules will be developed, to exploit strigolactones both functions, as exo-signals for a better harnessing of beneficial microbiome and as cue for deleterious organisms (e.g. to induce suicidal germination of parasitic plants). The smart formulated bioproducts / agricultural inputs and the agricultural practices intended to exploit their specific features of such bioproducts are an example of biotechnologies for agriculture. The natural strigolactones mimics will be a part of the microbial standardized extract, which we intend to produce from microalgae culture and which is another example of organic plant biostimulant. This microbial standardized extract will include natural strigolactones, polyamines and betaines. Both strigolactones and polyamines are exo- and endo-signals. As exo-signals, both strigolactones and polyamines have been demonstrated to enhance mycorrhizae hyphal branching and root colonization. As endo-signals, both strigolactones and polyamines are involved in plant stress responses. Betaine also supports plant response to stress, especially to drought. Strigolactone mimics used for laboratory screening will be synthetized based on a rational bio-design. The inorganic plant biostimulants are represented by selenium, as zerovalent nano-selenium. A large body of evidence demonstrates that selenium acts as a plant biostimulant. Selenium protects plants against abiotic stress, especially drought, enhances / benefits nutrient uptake and improves edible yield quality. Nanoselenium (zerovalent) particles show a much lower environmental impact and an improved efficiency compared to other selenium species. Application of selenium nanoparticles reduces the risk of accumulation of polyamines in the edible yield. From a food safety point-of-view, accumulation of polyamines in vegetables grown into HV mulch could have some carcinogenic effects, because polyamines were found to support proliferation of various tumor cells.

The project is an interdisciplinary one and address also other key topics as Environmental impact and risk assessment of the modern, new and emerging technologies and products. Safety and environmental impact of the new developed products will be determined by a state-of-art 3R techniques, by Norway partners. The project contributes to the objectives and the priorities of the call. It supports research cooperation between Romania and Norway and consolidate a strategic partnership.

Abstract:

Project TOTAL aims to investigate and integrate abiotic modulation and epigenetic control of Trichoderma strains within the context of Trichoderma interactions with biomass and living matter, for better harnessing of Trichoderma biotechnological potential. The specific objectives of the project are: (i) To establish and optimize the combined effects of light and nutrients on expression of proteins acting on plant cell walls and spore formation by Trichoderma strains; (ii) To optimize the deconstruction of plant cell walls by Trichoderma secreted proteins; (iii) To synergize the plant biostimulants effects of Trichoderma chlamydospores. The current approaches targeted the optimization of Trichoderma utilization either in agriculture or in biorefinery. The optimization of culture conditions have been in general focused either on improving sporulation to be used in biopesticides formulations or on the enzyme production for biomass deconstruction. Secondary products have been usually disregarded and discarded. An integrative technology to benefit from both advantages that Trichoderma offers has not been established. We plan to integrate the investigation of the fundamental aspects of Trichoderma development (light-, nutrient- and stress- mediated chlamydospore formation; cell signaling pathways; epigenetic effects) with its growth optimization for the use in both biomass valorization and plant biostimulant formulations.

Abstract:

BioNanoGum project proposal aims to develop an innovative biogenic nano-system for resolution of dysbiosis oral biofilms and inflammation involved in gingivitis and periodontitis, based on an innovative bacterial nanocellulose - fungal (nano)chitosan stimuli-responsive hydrogel, biogenic selenium nanoparticles (bioSeNPs), and hollow pollen shells filled with biogenic silica nanoparticles (bioSiOxNPs). Gingivitis and periodontitis affect more than 30% of globe population and can lead to teeth loss, but also other complications and severe diseases (Alzheimer, diabetes, autoimmune diseases). SeNPs, silicic acid released from SiOxNPs, and chitosan nano-structures determine (frank) resolution of dysbiosis biofilms and inflammation. However, there are also several drawbacks such as a very narrow physiological window (in the case of Se), or induced inflammation through a MAMPs similar mechanism, mediated by the Toll-like receptors (in the case of SiOxNPs). New formulations are needed in order to reduce risks of negative effects and to optimize the beneficial effects. BioNanoGum will use compounds acting complementary to SeNPs, which will lead to the reduction of Se dose. The pollen shells, obtained by Kombucha fermentation, will be used as encapsulation carriers for SiOxNPs, which allows bearing benefits from the anti-inflammatory, anti-bacterial and wound-healing effects of the silicic acid slowly released from bioSiOxNPs. The biogenic nano-system will deliver different components into a complementary manner and will act both on the resolution of pathogenic biofilms and on that of inflammation. BioNanoGum involves the niche between biotechnology and nanotechnology with health applications. This niche market has a significant growing potential, because it addresses several of the main health problems in the European Union and worldwide, from the beginning of the 21st century : an ageing population, with an increased incidence of non-communicable / chronic disease.

Abstract:

The project inscribes in the general concerns about environmental protection and human health and aims at developing and applying non-polluting agroecosystem practices that minimize the risk of infestation of crops with harmful agents. The technological optimization which will be provided within the project is harmonized with the current concerns in the field of soil functions management, water conservation and desertification control. The strategy proposed within the project support the sustainable agriculture by maximal valorization of the natural resources. The main aim of the project is to increase the productivity potential of agroecosystems affected by the climatic changes in terms of economic and environmental efficiency. The project will lead to realization and validation in real functioning conditions, of an agroecosystem management system based on new methods:(1) increase of soil fertility/ productivity and biodiversity preservation by application of conservative methods based on superior use of natural bio-resources, (2) reducing the plants vulnerability to limitative anthropic and ecological factors for crops, (3) decrease the risk for environment pollution with pesticides, by application of some methods based on analyses/ evaluation of the phytosanitary state of agroecosystems, (4) decrease of phytosanitary risks by application of ecological methods to control harmful agents, (5) preservation of the agroecosystems biodiversity by application of ecotoxicological methods to assess the environmental risks. Field experiments will be performed on soy and tomato crops. These crops were chosen as reference agroecosystems due to:(a) significant impact of the climate changes on these crops, (b) the need to replace the polluting management systems with non-polluting ecological methods. The essential concept of the project proposal is based on original solutions in the project field, patented by CO/ ICDPP (22 patents) and P4/ INMA (2 patent applications).
