Abstract

Oomycetes are eukaryotic microbes that are pathogenic to plants and animals. Pythiaceae is a family of oomycetes that can infect a variety of hosts causing Pythium Root Rot. Phenotypic differences between isolates of the same species may indicate aggressiveness. These isolates were used in in vitro plate experiments, growth rates, and in oogonia counts. In planta these isolates were used to infect maize from line B73.

Hypotheses:

• There is phenotypic diversity across different isolates of oomycetes within the same species when grown on different media.
• Some phenotypes are correlated with increased disease severity or aggressiveness in maize.
