Abstract/Contents:"Tall fescue infected with a fungal endophyte (Neotyphodium coenophialum) has increased survival under heat and drought conditions compared to non-infected tall fescue. However, the mechanism for endophyte-enhanced drought tolerance is unclear. Trehalose, a disaccharide, is a known osmoprotectant in desiccation tolerant organisms. To determine whether trehalose is a factor in desiccation tolerance of endophyte cultures and endophyte-infected plants, carbohydrate analysis using gas chromatography was conducted. Endophyte cultures subjected to stress conditions on osmotically adjusted growth media exhibited growth differences and changes in carbohydrate profiles. A field drought study comparing growth and carbohydrate responses of well-watered and water-stressed grasses will be discussed."
