Study of Flax Rust Combat Suggests New Strategy for Plant-Disease Control

This article gives insight into flax seed 'rust' control through genetics. Experiments revealed that the tiny entities known as genes within the cells of both the plant and its rust parasite (also a plant) were pitted against each other. So it's gene against gene when rust attacks flax? the genetic virulence of a rust race opposing the genetic resistance of a flax variety. Dependent upon the gene interaction, a characteristic growth, or "pustule is produced on the flax tissue
