NANOCROPTECTIVE nanotechnology with seed bio-stimulant microbial molecules to potentiate crop growth and immunization for techtransfer

Seed germination is the first step of a sequence of events that promote the transit of seeds from dormancy to vegetative growth. Therefore, it is a tightly regulated program that ensures further plant growth and survival in a supportive environment. The emergency provoked by continuous deterioration of the environment due to non-respectful crop management strategies and potentiated with climate change has increased the focus on this primordial stage of the plant growth as a primary target of strategies that help mitigating unsustainable issues. Beneficial microbes live in association with all plants, and we know how to take advantage of this benefit for the wealth of adult plants; however, little is known on their contribution to seed resilience and adaptation to a changing environment. This lack of knowledge may lead to unfeasible and weak bio-stimulant results undermining their credibility and entry into the market.

In this scenario, researchers at the BacBio Group, affiliated with Universidad de Málaga in Spain, are developing Nanocroptective, a nanotechnology-based seed bio-stimulant aimed at enhancing crop growth and resilience in changing environments.

The technology developed by the researchers is based on the use of the bacterium Bacillus subtilis to stimulate seed germination and promote plant growth.
Two specific components of the extracellular matrix of this bacterium modify lipid metabolism and the accumulation of glutathione-related molecules in seeds, thus affecting their development and plant resistance to pathogens such as the fungus Botrytis cinerea.
Additionally, these molecules will be integrated into an enhanced nanotechnology platform to improve and increase the mobilization of nutrients from the oil bodies contained within the seeds. These nanoparticles are carbon-based and environmentally inert.

Benefits:

  • Stimulates seed germination and promotes plant growth, potentially leading to enhanced productivity.
  • Improves plant resistance to pathogens, such as the Botrytis cinerea fungus, thus reducing the need for pesticides and fungicides.
  • Utilizes carbon-based nanoparticles, which are environmentally neutral, thereby mitigating negative impacts on ecosystems and human health.

The represented institution is looking for a collaboration that leads to a commercial exploitation of the presented invention and subsequently the potential transfer of the technology.
