Abstract:
When dormant seeds of wild oat were challenged in vitro with Fusarium avenaceum isolate ‘F.a.1’, biochemical and molecular seed defense responses were induced and seeds were decayed. However, the ability of this isolate to cause decay in a soil system has not been demonstrated. Therefore, we are exploring the potential of fungi to decay dormant wild oat seeds in soil. Our objectives were to 1) develop a robust and repeatable soil-based method for assessing seed decay following exposure to fungi, and 2) evaluate the effect of variable soil properties on seed decay. Seed decay and seed viability were quantified. The abundance of the Fusarium isolate in soil and in the seeds was determined using RT-qPCR. To assess the effects of soil properties on seed decay, wild oat was sown in a diversity of soils inoculated with Fusarium. Additional progress on this research will be presented.
