Plants, as sessile organisms, have evolved an exquisitely tuned response network to survive environmental perturbations. Organelles-to-nucleus signaling, termed retrograde signaling, plays a key role in stress responses by communicating subcellular perturbations to the nucleus, thereby coordinating expression of stress specific nuclear genes essential for adaptive responses to hostile environment. Recently, several stress specific retrograde signals have been identified; most notable amongst them are reactive oxygen species, tetrapyrroles, 2-C-methyl-d-erythritol 2,4-cyclodiphosphate (MEcPP), unsaturated fatty acids, nitric oxide (NO), 3'-phosphoadenosine 5'-phosphate (PAP), and β-cyclocitral (β-CC). It is expected that this trend will continue to provide fundamental insight into the integrative network of sensory systems central to the adaptive responses of plants to the prevailing environment. This review focuses on the recent advancements in the field.
植物作为固着生物，已经进化出一套精细的响应网络来适应环境变化。细胞器到细胞核的信号传递，即逆行信号传递，通过将亚细胞扰动传递到细胞核来在应激反应中发挥关键作用，从而协调表达应激特异性核基因，这些基因对于适应恶劣环境的反应至关重要。最近，已经确定了几种应激特异性逆行信号，其中最值得注意的是活性氧、四吡咯、2-C-甲基-D-赤藓醇 2,4-环二磷酸（MEcPP）、不饱和脂肪酸、一氧化氮（NO）、3'-磷酸腺苷 5'-磷酸（PAP）和β-环柠檬醛（β-CC）。预计这种趋势将继续为植物适应环境的感知系统的综合网络提供基础见解。本综述重点介绍了该领域的最新进展。
