Abstract/Contents:"A detailed understanding of molecular mechanisms is required for improving heat tolerance in cool-season turfgrasses. The objective of the current study was to identify major lipids and oxygenated fatty acids (oxylipins) and their associated metabolic roles in driving heat tolerance in two hard fescue genotypes with distinct levels of heat tolerance. Harf fescue genotypes '219' and '141' were exposed to control (22/18 °C; day/night) and heat stress (35/30°C; day/night) treatments in growth chambers for 21 days. No differences in turf quality were observed between the two genotypes throughout the control treatment. However, genotype '141' maintained greater turf quality, percent green cover, photochemical efficiency, and non-photochemical quenching compared to '219' at 21 days of heat stress, indicating its superior heat tolerance. The lipidomic analysis identified several differentially regulated lipids and oxylipins in '141' and '219' genotypes in response to 21 days of heat stress. Identified lipids and oxylipins are crucial underlying metabolites associated with heat tolerance in hard fescue and can potentially serve as biomarkers for improving heat tolerance in cool-season turfgrasses."
