Elvin Stakman - (ANSWER)this man worked with trying to understand the stem rust pathogen but
resistance could not be met due to genetic variation
Harold Flor - (ANSWER)this man proposed gene to gene concept, allowed plant to detect presence of
pathogen, controlled death of attacked plant cell, prevents spreading, was only effective against
biotrophic pathogens
Barberry - (ANSWER)what bush was eradicated to prevent stem rust

Late Blight of Potato - (ANSWER)devastated the Irish population, is a fungal-like pathogen, infects potato
and tomatoes, thrives in wet conditions and high humidity, tends to cause symptoms later in season,
wind dispersed, infects leaves and tubers, overwinters in tubers, introduced by ships carrying bird

Antoine Parmentier - (ANSWER)potatoes were not popular when introduced into Europe who promoted
them to the French court in 1760 which then fueled population growth and urbanization
