Representative photographs showing the differential response of roots of cowpea cultivar B301 to infection by two different races of S. gesnerioides. (A) Roots infected with S. gesnerioides race SG3 at 6 days post-inoculation (dpi) showing a hypersensitive response; (B) Roots infected with S. gesnerioides race SG3 at 13 dpi showing a hypersensitive response and parasite death; (C) Roots infected with S. gesnerioides race SG4z at 6 dpi showing early penetration of host; (D) Roots infected with S. gesnerioides race SG4z at 13 dpi showing parasite growth.
