Abstract Detail
Poster Session Imboden, Lori [1], Afton, Drew [1], Trail, Frances [1]. Fusarium graminearum ingress of the barley palea via phytoliths. Phytoliths are silica-filled cells that accumulate in plant tissue and are present in varying concentrations and morphologies based on plant species and environmental conditions. Grasses in particular are rich with phytoliths even in soil with low silicon content. While silica is generally associated with plant defense against pathogens and insects, we have observed a bias towards ingress by the phytopathogen Fusarium graminearum at phytoliths on the palea of inoculated excised barley florets. We have an ongoing characterization of fungal ingress at phytoliths on barley varieties with varying morphotypes. The kinetics of the fungal interaction with plant phytoliths and surface penetration in the context of fungal resistance/susceptibility will be discussed.
