We are very happy to have contributed essential resources and services to this outstanding story that has been many years in the making. Briefly, the question on the outset was: “Is the overyielding sometimes observed when strains of the same species are grown together genetically tractable (i.e. strain A monoculture = productivity X; strain B monoculture = productivity Y; strains A & B grown together = productivity Z > X or Y)?” Through relentless and rigorous analyses, our colleague Sam Wuest, then at the University of Zurich, now at Agroscope, mapped overyielding in an Arabidopsis pairing to polymorphisms at a single gene locus, the SUC8 gene. This provides proof of concept that the answer is “Yes, it is!”
