植物发育和发育事件的时间（物候）与植物适合度密切相关。各种内部和外部因素决定了这些生活史转变的时间和健康后果。微生物在植物的整个生活史中与植物相互作用，并影响宿主的物候。本文综述了当前围绕微生物驱动的植物物候变化的机制和理论知识。总的来说，有微生物影响每一个物候转变的例子。虽然大多数研究都集中在开花时间，微生物的影响仍然是重要的主机生存和健身在所有物候期。微生物介导的营养获取和植物激素信号传导的变化可以将植物从胁迫条件下释放出来，并改变植物的胁迫反应，诱导发育事件的转变。物候效应的频率和方向似乎部分取决于生活方式和植物-微生物相互作用的基本性质（即，共生或致病），除了微生物的分类组（真菌与细菌）。最后，我们强调偏见，知识差距和未来的方向。这种植物适应性可塑性的生物来源将在维持植物生物多样性和在气候变化压力下管理农业方面发挥重要作用。
Plant development and the timing of developmental events (phenology) are tightly coupled with plant fitness. A variety of internal and external factors determine the timing and fitness consequences of these life‐history transitions. Microbes interact with plants throughout their life history and impact host phenology. This review summarizes current mechanistic and theoretical knowledge surrounding microbe‐driven changes in plant phenology. Overall, there are examples of microbes impacting every phenological transition. While most studies have focused on flowering time, microbial effects remain important for host survival and fitness across all phenological phases. Microbe‐mediated changes in nutrient acquisition and phytohormone signaling can release plants from stressful conditions and alter plant stress responses inducing shifts in developmental events. The frequency and direction of phenological effects appear to be partly determined by the lifestyle and the underlying nature of a plant–microbe interaction (i.e., mutualistic or pathogenic), in addition to the taxonomic group of the microbe (fungi vs. bacteria). Finally, we highlight biases, gaps in knowledge, and future directions. This biotic source of plasticity for plant adaptation will serve an important role in sustaining plant biodiversity and managing agriculture under the pressures of climate change.
