Infection genetics: gene-for-gene versus matching-alleles models and all points in between

摘要: Here we address the controversy between plant pathologists and invertebrate zoologists as to genetic basis of infection. We show that alternative models proposed by these groups represent two ends a continuum. Specifically, gene-for-gene (GFG) model represents one end continuum, where very broad host range is expected occur in pathogen genotype. The matching alleles (MA) model, favoured zoologists, opposite same an exact match required for Since it known matching-alleles give highly dynamical behaviour selection recombination if parasites exert strongly negative effects on fitness, were especially interested determining nature any such interior regions MA–GFG found aspects observed across most would increase geometric mean fitness over about half
