Recognition responses following transient, Agrobacterium tumefaciens-based expression of Avr-vnt1 in S. okadae. Accessions resistant to P. infestans genotype 13-A2, 7129, 7625, and 7629, yield a visible response whereas susceptible accessions 3761 and 7775 yield no specific response if compared to empty vector control. (A) Graph representing phenotypic response at the Avr-vnt1 infiltration sites from at least three independent replicates. Plants were scored at 5 dpi. A score of zero represent no HR and a score of one indicates that at least half the infiltrated leaf area responded with a cell death response. (B) Pictures of the infiltration sites of the empty vector control and Avr-vnt1 visualized under white light at 5 dpi. Transient expressions were performed by infiltration of A. tumefaciens strain Agl1, at an OD600 of 0.2.
