Scientists at the NEIKER-Tecnalia Basque Institute for Agricultural Research and Development have studied the genetic structure of Phytophthora infestans —responsible for potato blight—.

Científicos del Instituto Vasco de Investigación y Desarrollo Agrario, NEIKER-Tecnalia han realizado el estudio de la estructura genética de Phytophthora infestans -causante del tizón tardío de la papa- y han identificado por primera vez en España la existencia del genotipo Blue13 (13_A2).
