| Abstract/Contents: | "Oxalate oxidase, an enzyme that degrades oxalic acid (OA) to CO2 and H2O2, has been characterized in some plant species, such as barley, and has also been associated with the responses of barley to pathogens. Although dollar spot, caused by S. homoeocarpa, is one of the primary turfgrass diseases in USA, the interaction between bentgrass and S. homoeocarpa is poorly understood. In this work, we observed that S. homoeocarpa produces OA during the infection process. In order to determine if oxalate oxidase is involved in the response of bentgrass to dollar spot, cultivars Crenshaw, Emerald, and L-93 were inoculated with S. homoeocarpa. Oxalate oxidase activity increased from 12 units/g FW at 24 h.a.i. in the most resistant cultivar (L-93), to 35 units/g FW at 48 h.a.i. The same cultivars were also sprayed with potassium oxalate (KOx), methyl jasmonate (MeJA), or acibenzolar Smethyl (ASM). Oxalate oxidase activity was induced by KOx and MeJA. We are investigating if treatment with KOx or MeJA induces resistance in bentgrass to S. homoeocarpa through increases of oxalate oxidase activity." |
