Various strategies evolved in plants to adjust the position of organs relative to the prevailing temperature condition, which allows optimal plant growth and performance. Such responses are classically separated into nastic and tropic responses. During plant thermotropic responses, organs move towards (engage) or away (avoid) from a directional temperature cue. Despite thermotropism being a classic botanical concept, the underlying ecological function and molecular and biophysical mechanisms remain poorly understood to this day. This contrasts to the relatively well-studied thermonastic movements (hyponasty) of e.g., rosette leaves. In this review, we provide an update on the current knowledge on plant thermotropisms and propose directions for future research and application.
植物进化出了各种策略来调整器官相对于当前温度条件的位置，以实现植物的最佳生长和性能。这类反应传统上分为感性运动和向性运动。在植物的热向性反应中，器官会朝着（趋向）或远离（避开）定向温度信号移动。尽管热向性是一个经典的植物学概念，但至今其潜在的生态功能以及分子和生物物理机制仍知之甚少。这与例如莲座叶相对研究较多的热感性运动（偏上性）形成了对比。在本综述中，我们更新了关于植物热向性的当前知识，并提出了未来研究和应用的方向。
