A precise and versatile nanotechnology with seed bio-stimulant microbial molecules to potentiate crop growth and immunization

Introduction

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.

Environmental Challenges

The emergency provoked by continuous deterioration of the environment due to non-respectful crop management strategies, potentiated by climate change, has increased the focus on this primordial stage of plant growth. It has become a primary target for strategies that help mitigate unsustainable issues.

Role of Beneficial Microbes

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 about 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.

Proposed Solution

Supported by findings from our deep investigation on the mutualistic interaction between microbes and seeds, we propose a proof of concept for a precise and customizable strategy based on the use of fengycin. This molecule is produced by Bacillus cells in interaction with seeds, and we will employ a fine-tuned nanotechnology platform to improve and increase the mobilization of nutrients from oil bodies containing seeds.

Expected Outcomes

We expect the following outcomes from our approach:

1. Better adaptation of plantlets to the environment.
2. Major adult plant growth.
3. Immunization against microbial pathogens.
4. An average 50% reduction in the use of fertilizers and pesticides.

Conclusion

Altogether, our methodology should serve to improve the credibility of biological solutions as potent bio-stimulants for seed growth. Thus, it will enhance their inclusion in sustainable programs of crop production and protection.
