| Abstract: | Background Oomycetes attack a huge variety of economically and ecologically important plants. These pathogens release, detect and respond
to signal molecules to coordinate their communal behaviors including the infection process. When signal molecules are present
at or above threshold level, single zoospores can infect plants. However, at the beginning of a growing season population
densities of individual species are likely below those required to reach a quorum and produce threshold levels of signal molecules
to trigger infection. It is unclear whether these molecules are shared among related species and what their chemistries are. |
