A major part of the human diet is made up by seeds such as wheat, rice and maize; both as staple crops and as raw material for livestock feed. The yield of these crops is highly dependent on successful flower development, pollination and proper timing of seed set. However, significant yield loss is caused by stress factors such as excessive heat and drought, which are being exacerbated by ongoing climate change (Zhao et al. 2017). Pollen development, in particular, is highly sensitive to heat stress (Mesihovic et al. 2016) and in an effort to enhance our understanding of plant responses to heat stress, with the view of aiding breeding efforts, Bheemanahalli et al. (2020) used metabolic and hormonal profiling to investigate the regulation of heat stress tolerance in two wheat genotypes.

太热了，热应激对作物产量的不利影响

人类饮食的主要部分是由小麦、水稻和玉米等种子构成的。既可作为主要作物，也可作为牲畜饲料的原料。这些作物的产量高度依赖于成功的花朵发育、授粉和种子结实的适当时机。然而，高温和干旱等压力因素会导致显着的产量损失，而持续的气候变化正在加剧这些因素（Zhao et al. 2017）。特别是花粉发育对热应激高度敏感（Mesihovic 等人，2016 年），为了帮助育种工作，Bheemanahalli 等人努力提高我们对植物对热应激反应的理解。(2020) 使用代谢和激素分析来研究两种小麦基因型热应激耐受性的调节。
