Models Illustrating the Potential Link between Association of AVR2 Family Members with BSL1 and R2-Mediated Recognition and Resistance.
Activation of R2 by AVR2 could be mediated by an AVR2-modifed BSL1, BSL1-modified AVR2, or AVR2-BSL1 complex (left to right). Circles, corresponding effectors; yellow diamonds, BSL1; green rectangles, R2. Potential modifications are indicated by red highlighting.
