| Abstract/Contents: | "Drought is one of the major abiotic stresses that affect plant growth. To investigate drought tolerance mechanisms in warm-season turfgrass species, a physiological and comparative proteomic analysis was carried out in two bermudagrass (cynodon spp.) cultivars differing in drought tolerance. Two cultivars ('Tifway' and 'C299') of bermudagrass developed gradual water stress over 15 days without watering, while the control treatments were maintained well-watered. Drought stress significantly increased leaf relative electrolyte leakage and decreased leaf chlorophyll fluorescence (Fv/Fm), as well as relative water content. 'Tifway' exhibited better drought tolerance than 'C299'. Total proteins of leaves were extracted from well-watered and drought-stressed plants at 10 days after treatment, separated by two-dimensional gel electrophoresis (2-DE) and stained with colloidal coomassie brilliant blue (CBB). Out of about 750 protein spots reproducibly detected, 32 proteins had increases in abundance and 22 proteins exhibited decreases in abundance, and no changes were detected in the remaining number of proteins. All the drought-responsive proteins were excised from gels and subjected to mass spectrometry analysis, leading to identification of 51 proteins involved in metabolism, energy, cell growth/division, protein synthesis, and disease/defence. The results suggest that the superior drought tolerance in 'Tifway' could be mainly attributed to higher photosynthetic capacity, as indicated by more stable photosynthetic proteins and less degradative energetic proteins and greater levels of antioxidant enzymes related to the control of reactive oxygen species (ROS)." |
