Phytohormone based biostimulant combined with plant growth promoting endophytic fungus enhances Ni phytoextraction of Noccaea goesingensis

To improve the efficiency of Ni phytoextraction, metal hyperaccumulator N. goesingensis was subject to treatment with a combination uptake stimulating microorganism and commercially available, IAA- based biostimulating seaweed extract - Kelpak. Additionally, we compared plant growth promoting capabilities two biofertilizers. Treatment Kelpak alone had no significant effect on or accumulation. Inoculation Phomopsis columnaris significantly improved biomass hyperaccumulating yield per several biometric features such as fresh dry weight others related leaf root size. However, treatments yielded best results; plants treated agents 85% more not accumulated 48% plant. verify inoculation fungus generated GFP expressing strain P. visualized in both leaves roots. trace development planta evaluate biostimulant mycelium fungal translational elongation factor 1α (tef1α) DNA quantified qPCR. Upon biofertilizer abundance increased nearly 5-fold. The utilization microorganisms, endophytic fungi particular, can phytoextraction goesingensis.
