Abstract/Contents: | "Drought stress is a major abiotic stress limiting the growth of cool-season grass species, such as creeping bentgrass (Agrostis stolonifera). Enhanced drought tolerance and turf recovery upon re-watering are valuable traits that deserve further investigation. Inoculation with plant growth promoting rhizobacteria (PGPR) can help reduce the impacts of drought stress in plants by encouraging root growth and reducing endogenous plant ethylene levels. However, the specific mechanisms of interaction between creeping bentgrass plants and their microbial symbionts remain poorly understood. A novel strain of Burkholderia bacteria was used to inoculate the roots of creeping bentgrass (cv. Penncross). The plants were subjected to 35 days of drought stress treatments, followed by a 15 day period of re-watering in growth chamber trials. Turf quality, canopy density, DGCI (dark green color index), and tiller production were quantified during the drought stress and recovery periods, with inoculated plants demonstrating greater drought tolerance and recuperative ability in response to re-watering. Under drought stress, inoculated plants also showed reduced ethylene production, increased soluble sugars in the crowns, and greater root viability than non-inoculated plants. These findings provide insights into the mechanisms that are responsible for conferring enhanced drought tolerance and recovery of creeping bentgrass inoculated with this novel Burkholderia strain." |
