Adapting to varying phosphate levels in the environment is vital for plant growth. The PHR1 phosphate starvation response transcription factor family, along with SPX inhibitors, plays a pivotal role in plant phosphate responses. However, this regulatory hub intricately links with diverse biotic and abiotic signaling pathways, as outlined in this review. Understanding these intricate networks is crucial, not only on a fundamental level but also for practical applications, such as enhancing sustainable agriculture and optimizing fertilizer efficiency. This comprehensive review explores the multifaceted connections between phosphate homeostasis and environmental stressors, including various biotic factors, such as symbiotic mycorrhizal associations and beneficial root-colonizing fungi. The complex coordination between phosphate starvation responses and the immune system are explored, and the relationship between phosphate and nitrate regulation in agriculture are discussed. Overall, this review highlights the complex interactions governing phosphate homeostasis in plants, emphasizing its importance for sustainable agriculture and nutrient management to contribute to environmental conservation.
适应环境中变化的磷酸盐水平对植物生长至关重要。PHR1 磷酸盐饥饿响应转录因子家族与 SPX 抑制剂一起，在植物磷酸盐响应中发挥关键作用。然而，正如本文综述所述，这个调控中心与多种生物和非生物信号通路错综复杂地联系在一起。了解这些复杂的网络不仅在基础层面上很重要，而且对于提高可持续农业和优化肥料效率等实际应用也很重要。本综述探讨了磷酸盐稳态与环境胁迫因子之间的多方面联系，包括共生菌根共生体和有益的根定殖真菌等各种生物因素。还探讨了磷酸盐饥饿响应与免疫系统之间的复杂协调关系，以及农业中磷酸盐和硝酸盐调节之间的关系。总的来说，本文综述强调了控制植物磷酸盐稳态的复杂相互作用，突出了其对可持续农业和养分管理的重要性，以有助于环境保护。
