Answer
Nikolai Vavilov, a prominent botanist and geneticist, fell victim to the influence of Trofim Lysenko, a Soviet biologist who championed the discredited theory of Lysenkoism. Lysenko's dominance in Soviet science during the mid-20th century led to the persecution and suppression of geneticists who disagreed with his views. Tragically, Vavilov faced unjust accusations, imprisonment, and ultimately execution in 1943, a consequence of Lysenko's influence and the prevailing political climate.
