| Abstract/Contents: | "Drought stress is a major limiting factor for warm-season turfgrass growth during the summer in the U.S. transition zone. Genotypic variation in drought resistance exists among bermudagrasses (Cynodon spp.) but the mechanisms of drought resistance are poorly understood. The objectives were to quantitatively profile membrane lipid molecule species in three bermudagrass cultivars under well-watered condition and drought stress and to identify relationships between specific lipid compositions and drought tolerance. Grasses included a high drought resistance cultivar 'Celebration', low drought resistance cultivar 'Premier', and a new released cultivar 'Latitude 36'. When exposed to drought treatment, the amount of monogalactosyldiacylglycerol (MGDG) lipids decreased by 4% in 'Latitude 36' and 5% in 'Premier'. Under drought treatment, MGDG in 'Premier' was 3% and 7% higher, respectively, than in 'Latitude 36' and 'Celebration'. Monogalactosyldiacylglycerol (MGDG) was more sensitive to degradation than digalactosyldiacylglycerol (DGDG). The unsaturation level of polar lipids decreased in the drought sensitive cultivar 'Premier', whereas it remained unchanged in 'Celebration' and 'Latitude 36'. All classes of phospholipid contents were highest in 'Celebration' under drought stress. 'Premier' showed a higher content of phosphatidylethanolamine (PE) and a lower content of phosphatidylserine (PS) when compared to 'Latitude 36' after exposure to drought stress. These results indicate that lower MGDG and higher phospholipid contents contribute to drought tolerance in bermudagrass." |
