| Abstract/Contents: | "Drought stress results in significant reductions in turf quality of cool season grasses such as creeping bentgrass (Agrostis stolonifera). Investigating strategies to improve drought tolerance and recovery upon re-watering remain important areas of research for turfgrass management. Plant growth promoting rhizobacteria (PGPR) can help to improve abiotic stress tolerance and recovery in cool season grasses by regulating metabolites; however the specific mechanisms involved require further investigation. This study conducted an LC-MS analysis of the metabolic profile of the root tissue of creeping bentgrass (cv. 'Penncross') that was inoculated with a novel strain of Burkholderia bacteria that possesses growth promoting properties. Inoculated plants and non-inoculated controls were subjected to 35 days of drought stress, followed by a 15-day recovery period in which the plants were re-watered. The inoculated plants demonstrated enhanced drought tolerance and post-drought recovery, as indicated by greater root growth and root viability compared to non-inoculated plants. The metabolic profile of the inoculated plants demonstrated increased concentrations of amino acids, osmoregulants, and carbohydrates during drought stress, helping to explain the physiological and morphological responses that resulted in improved stress tolerance. Phytohormone analysis also indicated that inoculation increased c-Zeatin and t-Riboside during the drought stress and recovery periods, while reducing ABA to a greater degree upon re-watering." |
