It is expected that C3 herbage grass have severe damage in their yield and growth under forecasted climate warming. In this study, interspecific differences in heat stress tolerance among C3 grasses was investigated from the view point of expression of heat shock protein. All C3 grass showed HSP expression shortly after heat exposure. However, interspecific difference in heat tolerance can not be explained by the expression pattern of heat shock protein. A part of this study revealed involvement of oxidative stress as a cause for heat stress damage. This data suggest the future direction of this research.

预计在预测的气候变暖的情况下，C3牧草的产量和生长将受到严重损害。本研究从热休克蛋白表达的角度研究了C3禾本科热应激耐受性的种间差异。所有 C3 草在热暴露后不久都表现出 HSP 表达。然而，热耐受性的种间差异不能用热休克蛋白的表达模式来解释。这项研究的一部分揭示了氧化应激是热应激损伤的一个原因。这些数据表明了这项研究的未来方向。
