C perennial bioenergy grasses are an economically and ecologically important group whose responses to climate change will be important to the future bioeconomy. These grasses are highly productive and frequently possess large geographic ranges and broad environmental tolerances, which may contribute to the evolution of ecotypes that differ in physiological acclimation capacity and the evolution of distinct functional strategies. C perennial bioenergy grasses are predicted to thrive under climate change-C photosynthesis likely evolved to enhance photosynthetic efficiency under stressful conditions of low [CO], high temperature, and drought-although few studies have examined how these species will respond to combined stresses or to extremes of temperature and precipitation. Important targets for C perennial bioenergy production in a changing world, such as sustainability and resilience, can benefit from combining knowledge of C physiology with recent advances in crop improvement, especially genomic selection.
多年生生物能源草是一个具有重要经济和生态意义的群体，它们对气候变化的反应对未来的生物经济将非常重要。这些草具有很高的生产力，通常具有较大的地理范围和广泛的环境耐受性，这可能有助于形成在生理适应能力上存在差异的生态型，并形成不同的功能策略。多年生生物能源草预计将在气候变化下茁壮成长——C4 光合作用可能是为了在低[CO2]、高温和干旱等胁迫条件下提高光合作用效率而进化的——尽管很少有研究探讨这些物种将如何应对综合胁迫或温度和降水的极端情况。在不断变化的世界中，可持续性和弹性等是多年生生物能源生产的重要目标，将 C 生理学知识与作物改良的最新进展（特别是基因组选择）相结合，可以从中受益。
