Abstract

Plants alter their metabolism in order to coordinate the communication between aerial and underground parts to achieve the best allocation of resources and sustain plant growth and productivity. Moreover, the plant nutritional status and external availability of nutrients will modulate the three-dimensional arrangement of root development, its growth, and, therefore, the entire plant metabolome. In this sense, phosphorus (P) appears as one of the essential nutrients for survival of all plant species and its deficiency responses are already broadly characterized for different crops, such as soybean. In recent years, the utilization of protein biostimulants is gaining more attention in agriculture field due to its environmental friendly approach and good results on plant productivity. However, the mechanisms of how those biostimulants works on plants still must be more deeply understood. Our ongoing Post-Doctoral project (FAPESP Project number: 2017/15939-1) has selected a good biostimulant candidate based on yeast protein extracts. This biostimulant promotes an increase of root and shoot growth in soybean plants growing in P deficient soils. Therefore, the aim of the present purpose is now to evaluate how this yeast biostimulant affects aerial and underground soybean metabolisms and understand the way in which those changes may contribute to the better performance observed under P deficiency stress.
