Abiotic stresses and soil nutrient limitations are major environmental conditions that reduce plant growth, productivity and quality. Plants have evolved mechanisms to perceive these environmental challenges, transmit the stress signals within cells as well as between cells and tissues, and make appropriate adjustments in their growth and development in order to survive and reproduce. In recent years, significant progress has been made on many fronts of the stress signaling research, particularly in understanding the downstream signaling events that culminate at the activation of stress- and nutrient limitation-responsive genes, cellular ion homeostasis, and growth adjustment. However, the revelation of the early events of stress signaling, particularly the identification of primary stress sensors, still lags behind. In this review, we summarize recent work on the genetic and molecular mechanisms of plant abiotic stress and nutrient limitation sensing and signaling and discuss new directions for future studies.
非生物胁迫和土壤养分限制是降低植物生长、生产力和品质的主要环境条件。植物已经进化出感知这些环境挑战的机制，在细胞内以及细胞和组织之间传递胁迫信号，并在生长和发育方面做出适当的调整，以生存和繁殖。近年来，在应激信号研究的许多方面都取得了重大进展，特别是在理解应激和养分限制响应基因、细胞离子稳态和生长调节的下游信号事件方面。然而，应激信号早期事件的揭示，特别是主要应激传感器的鉴定，仍然滞后。在这篇综述中，我们总结了植物非生物胁迫和养分限制感知和信号转导的遗传和分子机制的最新研究进展，并讨论了未来研究的新方向。
