英文摘要	The effects of global warming are the environmental and social changes caused directly or indirectly by human emissions of greenhouse gases. Impacts of climate change have already been evidenced by observed glacier retreat, changes in the timing of seasonal events (e.g., earlier flowering of plants) and changes in agricultural productivity. Climate change threatens crop harvests not only by storm-, flooding- and drought-caused physical damage, but also by heat stress-induced changes in physiological processes. In China alone, there are six recorded heat damages in the past 50 years, and in particular, heat stress affected 3 million hectares and reduced grain production by 5 million tons in 2003 [1]. Unlike other biotic and abiotic stresses such as pests and drought, which can be managed to certain extent by agricultural practices, air temperature on an open field is much beyond human’s control. Therefore, developing thermotolerant plants is probably the most effective choice to protect crop production under heat stress, although this issue has largely remained elusive. Fortunately, Li et al. [2] have recently identified a major quantitative trait locus (QTL) conferring heat tolerance and cloned the corresponding gene Thermo-tolerance 1 (TT1) from CG14 (Oryza glaberrima), a rice line long adapted in Africa for high temperature. This work is the first breakthrough in genetic mining of QTLs for crop thermotolerance and is of great significance for the increase in crop security threatened by global warming.
