“…A similar process might have occurred in this experiment. Auxin is known to be involved in many biological processes in plants, such as in signaling, transport, and root development ( Teale et al., 2006 ; Overvoorde et al., 2010 ), and phosphorus is a highly important nutrient affecting soybean culture yield ( Vieira et al., 2023 ) involved in processes such as nodulation and nitrogen fixation in soybean. The synthesis of these two components by the yeast might improve soybean nutrition and root development which may lead to an up-regulation of abiotic stress resistance and cell wall and carbohydrates synthesis pathways and a down-regulation of glycolysis and protein degradation and modification pathways.…”

Nowadays, many products are available in the plant biostimulants market. Among them, living yeast-based biostimulants are also commercialized. Given the living aspect of these last products, the reproducibility of their effects should be investigated to ensure end-users’ confidence. Therefore, this study aimed to compare the effects of a living yeast-based biostimulant between two different soybean cultures. These two cultures named C1 and C2 were conducted on the same variety and soil but in different locations and dates until the VC developmental stage (unifoliate leaves unrolled), with Bradyrhizobium japonicum (control and Bs condition) and with and without biostimulant coating seed treatment. The foliar transcriptomic analysis done first showed a high gene expression difference between the two cultures. Despite this first result, a secondary analysis seemed to show that this biostimulant led to a similar pathway enhancement in plants and with common genes even if the expressed genes were different between the two cultures. The pathways which seem to be reproducibly impacted by this living yeast-based biostimulant are abiotic stress tolerance and cell wall/carbohydrate synthesis. Impacting these pathways may protect the plant from abiotic stresses and maintain a higher level of sugars in plant.
