| USGA Summary Points: | Variability and stability of microbiomes in a nematode-tolerant and nematode-susceptible Bermudagrass cultivar is currently being tested. For this, samples of soil, root- and leaf endosphere have been taken, DNA has been extracted, and the extracts are currently being sequenced. These samples will be compared to samples from 2022 and will provide valuable information that is essential for developing microbial products in turf. 30 additional fungal endophytes were isolated from Bermudagrasses and identified by molecular methods. They were grouped into 7 distinct taxa and were tested for bioactivity against sting nematodes. Four strains showed significant nematicidal activities (Table 1 and Figure 1). Around 30 additional cultures were isolated, but have not yet been identified by molecular methods. Based on previous data, we modified our bioassay and extended it to 7 days. Extracts from the fungal strain Colletotrichum sp. showed strong nematicidal activity. To identify its bioactive compounds, we re-grew the strain and extracted organic compounds. This extract is currently being analyzed by HPLC-MS at the lab of a collaborator. Identifying these compounds provides insides into the mode of action of these bioactive fungi and can provide novel nematicides. |
