Freeze-induced cyanide toxicity does not maintain the cyanogenesis polymorphism in white clover (Trifolium repens).

American journal of botany - 1 Jul 2018

Kooyers Nicholas J, Hartman Bakken Bradley, Ungerer Mark C, Olsen Kenneth M

Abstract excerpt

PREMISE OF THE STUDY: The maintenance of adaptive polymorphisms within species requires fitness trade-offs reflecting selection for each morph. Cyanogenesis, the ability to produce hydrogen cyanide (HCN) after tissue damage, occurs in >3000 plant species and exists as a discrete polymorphism in white clover. This polymorphism is spatially distributed in recurrent clines, with higher frequencies of cyanogenic...
