Description
Elise Woodruff and Nate Hardy simulate how plant germs evolve their harmfulness in a 2024 paper. Vector-borne pathogens split their lives between plant hosts and the insects that carry them. Genes that help in one home can hurt in the other, a tug called pleiotropy. Their individual-based simulations, loosely modeled on a bacterium that plagues citrus and grapes, test how that tug steers virulence.
Even when the germ spends most generations inside plants, selection inside the insect can drag plant virulence sideways, sometimes maladaptively. The size of that drift depends on spread rate, time shares, and how load maps to harm in each home. Strong insect-side selection paired with rare insect residence produced the strangest outcomes. The model sharpens intuition about fast virulence shifts in the field.
