Recent methodological advances have uncovered tremendous microbial diversity
cohabiting in the same host plant, and many of these microbes cause disease. In this review …

Highlights•Pathogen virulence and plant resistance genes are among the most variable
genes.•Selection on resistance alleles tends to be diversifying or balancing.•It is unclear …

Existing paradigms for plant microevolution rarely acknowledge the potential impacts of
diverse microbiomes on evolutionary processes. Many plant-associated microorganisms …

The field of plant pathology has revealed many of the mechanisms underlying the arms race,
providing crucial knowledge and genetic resources for improving plant health. Although the …

Studies of plant–pathogen interactions have historically focused on simple models of
infection involving single host-single disease systems. However, plant infections often …

The community structure in the plant-associated microbiome depends collectively on host–
microbe, microbe–microbe and host–microbe–microbe interactions. The ensemble of …

The co-evolutionary relationship between plants and microbes has led to complex
mechanisms of offense and defense, primarily centering on the innate immune system of …

Understanding the symbiosis between plants and pathogenic microbes is at the core of
effective disease management for crops and managed forests. At the same time, plant …

Microbe–host interactions can be categorised as pathogenic, parasitic or mutualistic, but in
practice few examples exactly fit these descriptions. New molecular methods are providing …
