About event
Brandon Bioscience is focussed on creating crop solutions derived from the marine algae Ascophyllum nodosum (AN) through our PSI® (Plant Signal Induction) proprietary Technology platform. Our next generation of plant biostimulants have proven to provide tolerance to abiotic stress, enhance nutrient use efficiency and crop quality for optimum performance in In multi-seasonal field trials. However, the mechanisms of stimulation are still poorly studied and reported. Recently we have focused on understanding the effect of an Ascophyllum nodosum based biostimulant (PSI-759 - Sealicit) on fruit development and seed dispersal trait in Arabidopsis and oil seed rape (OSR) at genetic and physiological level. The results indicate that Sealicit is affecting the expression of the major regulator of pod shattering, INDEHISCENT, thus, improving pod firmness, reducing seed loss, and increasing harvested crop yield. In parallel, we have focused on gaining more insight into mechanisms related to enhance nitrogen use efficiency (NUE) by biostimulant PSI-362. PSI-362 has been formulated to work with grower’s fertiliser programs (i.e., as a coating in granular fertiliser) and allows for up to 25% reduction in nitrogen application without comprising crop yield and quality, providing an attractive solution for sustainable agriculture. The phenotypical and biochemical analysis supported by evaluation of differential expression of genetic markers involved in nitrate perception and transport (TaNRT1.1/NPF6.3), nitrate and nitrite reduction (TaNR1 and TaNiR1) and assimilation indicated (TaGDH2, TaGoGAT, TaGS1), that PSI-362 improves NUE through a defined mode of action. Finally, a comparative analysis of the PSI® Precision biostimulant PSI-362 and two commercial Ascophyllum nodosum extracts (ANEs) demonstrated that the NUE effect greatly differs depending on the ANE biostimulant used.
