Protein synthesis is a fundamental process for life and, as such, plays a crucial role in the adaptation to energy, developmentaland environmental conditions. For these reasons, and despite the general conservation of the eukaryotic translational machinery, it is not surprising that organisms with different lifestyles have evolved distinct mechanisms of regulation to adapt translation initiation to their intrinsic growth and development. Plants have clear peculiarities compared with other eukaryotes that have also extended to translation control. This review describes the plant-specific mechanisms for regulation of translation initiation, with a focus on those that modulate the eIF4F complexes, central translational regulatory hubs in all eukaryotes, and highlights the latest discoveries on the signaling pathways that regulate their constituents and activity.

蛋白质合成是生命的基本过程，因此在适应能量、发育和环境条件方面起着至关重要的作用。由于这些原因，尽管真核翻译机制普遍受到保护，但具有不同生活方式的生物体已经进化出不同的调节机制以使翻译起始适应其内在的生长和发育也就不足为奇了。与也扩展到翻译控制的其他真核生物相比，植物具有明显的特性。这篇综述描述了调节翻译起始的植物特异性机制，重点是那些调节 eIF4F 复合物的机制，所有真核生物中的中央翻译调节中心，
