The low molecular weight hydrocarbons produced by plants form a uniquely exciting group of compounds. Produced by a common biosynthetic route, they play multiple and complex roles in organismal, ecological, and atmospheric processes. While some of these compounds have clearly identified functions within plants, others are made for reasons not yet fully understood. Here, both light-dependent and light-independent emissions are reviewed, together with regulation of production and possible functions of light-dependent volatile organic carbon (VOC). In addition to issues regarding the phylogenetic origins of VOC emissions, the origins of the pivotal enzymes that give rise to the observed emission phenotypes are discussed. Studies on the evolution and regulation of their production and emission provide an amazing opportunity for scientists working from the molecular to the tropospheric scales to interact.

植物产生的低分子量碳氢化合物构成了一类独特而令人兴奋的化合物。它们通过共同的生物合成途径产生，在生物体、生态和大气过程中发挥着多重且复杂的作用。虽然其中一些化合物在植物体内的功能已被明确确定，但其他一些化合物产生的原因尚未完全明了。在此，我们对光依赖型和非光依赖型排放进行综述，同时探讨光依赖型挥发性有机碳（VOC）的产生调控及可能的功能。除了VOC排放的系统发育起源问题外，还讨论了导致观察到的排放表型的关键酶的起源。对其产生和排放的进化及调控的研究为从分子尺度到对流层尺度开展工作的科学家提供了一个绝佳的互动机会。内容摘要199 一、引言199 二、非光依赖型排放200 三、光依赖型排放201 四、产生调控202 五、光依赖型VOC的可能功能204 六、植物源VOC的进化方面206 致谢206 参考文献209
