N2 - High temperature is a major abiotic stress limiting the growth and productivity of temperate plant species. Approaches to improving the heat tolerance of plants are critically important for maintaining plant growth and productivity, particularly in areas with prolonged periods of high temperatures. Stress priming by exposure of plants to mild drought stress or water deficit has been reported to be a viable method for improving heat tolerance in various plant species. The underlying mechanisms of drought priming-enhanced heat tolerance are multifaceted and complicated. Plant adaptation to multiple stresses incurred sequentially or simultaneously may involve reprogramming at molecular, biochemical, cellular, and physiological levels. Physiological processes, metabolic pathways, and gene networks that potentially contributed to drought priming-induced tolerance to subsequent heat stress will be discussed in this chapter.
