Outline of Final Research Achievements

Phosphorus is an essential agricultural fertilizer. Ensuring long-term availability and accessibility of phosphorus resources is critical to the future of humanity. A large amount of phosphite (oxidation state of +3) is produced as a waste in chemical and automotive industry. Direct utilization of phosphite (Pt) as a fertilizer would be very beneficial for the recycling of the Pt waste. However, phosphate (Pi) is the only chemical form of phosphorus that can be assimilated by plants. Pt dehydrogenase (PtxD), catalyzing oxidation of Pt to Pi, is a key enzyme for the efficient utilization of industrial Pt waste. An Arabidopsis thaliana recombinant carrying ptxD could grow on a medium containing Pt as a phosphorus source, while the wild type was unable to assimilate Pt.
