Transcription profiling of Arabidopsis seedlings treated with oligogalacturonides to assess how recognition of these compounds may contribute to defense against fungal pathogens

ABSTRACT: To assess the contribution to defenses against necrotrophic fungal pathogens that may be mediated by recognition of oligogalacturonides (OGs), cell wall fragments released by the activity of fungal polygalacturonases, we treated seedlings with OGs and assayed transcript levels 1 and 6 hours after addition of OGs to culture medium. For each sample, approximately 30 seedlings were grown in shallow liquid MS medium for 10 days. Plants were then treated with either 200 ug/ml OGs or, for control plants, an equal volume of water. Three replicate samples were assayed for each treatment.
