DOI: 10.1111/jeb.13896
Abstract: Abstract The COVID‐19 pandemic has led to a resurgence of the debate on whether host–parasite interactions should evolve towards avirulence. In this review, we first show that SARS‐CoV‐2 virulence is evolving, before explaining why some… read more here.

DOI: 10.1111/mpp.12898
Abstract: Abstract The soybean–Phytophthora sojae interaction operates on a gene‐for‐gene relationship, where the product of a resistance gene (Rps) in the host recognizes that of an avirulence gene (Avr) in the pathogen to generate an incompatible… read more here.

DOI: 10.1111/ppa.12935
Abstract: Magnaporthe oryzae avirulence (AVR) genes are predicted to be involved in pathogen invasion and their virulence functions are restricted by the presence of the cognate resistance (R) genes. In this study, the distribution and variation… read more here.
