| Abstract/Contents: | "Heat stress is a major factor limiting the growth of cool-season grasses in the transitional and warm climatic regions. Heat injury involves changes in protein metabolism. Protein degradation often occurs with increasing temperatures, but certain proteins such as heat shock proteins (HSPs) may be induced or enhanced in their expression under supraoptimal temperatures. One postulated mechanism for the acquisition of thermotolerance is synthesis of HSPs during exposure to high temperature (Park et al., 1996). The objectives of this study were to determine the critical temperatures that cause protein induction or degradation and to compare protein profiles between two Agrostis species contrasting in heat tolerance: heat resistant Agrostis scabra (ectotype 'Ntas') and heat sensetive Agrostis stolonifera (cv. 'Penncross'). Plants of both species were exposed to temperatures of 20, 30, 35, 40, and 45°C for 3,7 and 14 days. Soluble protein content was measured to evaluate general protein changes. Specific changes in protein profiles were imposed by using SDS-PAGE system. Photochemical efficiency and carotenoid content were also measured to evaluate the extent of heat injury. Our results suggested that protein degradation occurred at 35° in A. stolonifera and at 40°C in A. scabra. In addition, changes in leaf photochemical efficiency and carotenoid content with increasing temperatures confirmed that A. scabra was more heat tolerant than A. stolonifera, which could be explained by their differences in protein degradation and induction patterns." |
