Transgenic potato plants overexpressing the pathogenesis-related STH-2 gene show unaltered susceptibility to Phytophthora infestans and potato virus X.

Abstract excerpt

The STH-2 gene is rapidly activated in potato leaves and tubers following elicitation or infection by Phytophthora infestans. However, its biochemical function remains unknown. In order to ascertain if STH-2 protein is directly involved in the defense of potato against pathogens, the STH-2 coding sequence under the control of the CaMV 35S promoter was introduced into potato plants. Transgenic plants expressing...
