A few years ago, one of us (Ian) was lucky enough to be invited to visit the N.I. Vavilov Institute of Plant Industry in St Petersburg, Russia. Every plant breeder or geneticist knows of Nikolai Vavilov and his ceaseless energy in collecting important food crop varieties from all over the globe, and his application of genetics to plant improvement.

Vavilov championed the idea that there were Centres of Origin (or Diversity) for all plant species, and that the greatest variation was to be found in the place where the species evolved: wheat from the Middle East; coffee from Ethiopia; maize from Central America, and so on.

Hence the Centres of Origin (commonly known as the Vavilov Centres) are where you should start looking to find genotypes the set of genes responsible for a particular trait with disease resistance, stress tolerance or any other trait you are looking for. This notion applies to any species, which is why you can find more human genetic variation in some African countries than in the rest of the world combined.

By the late 1920s, as director of the Lenin All-Union Academy of Agricultural Sciences, Vavilov soon amassed the largest seed collection on the planet. He worked hard, he enjoyed himself, and drove other eager young scientists to work just as hard to make more food for the people of the Soviet Union.

However, things did not go well for Vavilov politically. How did this visionary geneticist, who aimed to find the means for food security, end up starving to death in a Soviet gulag in 1943?

Heroic science?

Enter the villain, Trofim Lysenko, ironically a protg of Vavilovs. The notorious Vavilov-Lysenko antagonism became one of the saddest textbook examples of a futile effort to resolve scientific debate using a political approach.

Lysenkos theories went against the latest science, but prevailed due to politics. Wikimedia

Lysenkos name leapt from the pages of history and into the news when Australias Chief Scientist, Alan Finkel, mentioned him during a speech at a meeting of chief scientists in Canberra this week.
