The GARP (Golden2, ARR-B, Psr1) family proteins with a conserved DNA-binding domain, called the B-motif, are plant-specific transcription factors involved in the regulation of various physiological processes. The GARP family proteins are divided into members that function as monomeric transcription factors, and members that function as transcription factors in the dimeric form, owing to the presence of a coiled-coil dimerization domain. Recent studies revealed that the dimer-forming GARP family members, which are further divided into the PHR1 and NIGT1 subfamilies, play critical roles in the regulation of phosphorus (P) and nitrogen (N) acquisition. In this review, we present a general overview of the GARP family proteins and discuss how several members of the PHR1 and NIGT1 subfamilies are involved in the coordinated acquisition of P and N in response to changes in environmental nutrient conditions, while mainly focusing on the recent findings that enhance our knowledge of the roles of PHR1 and NIGT1 in phosphate starvation signaling and nitrate signaling.

GARP（Golden2、ARR-B、Psr1）家族蛋白具有保守的 DNA 结合域（称为 B 基序），是参与多种生理过程调节的植物特异性转录因子。由于存在卷曲螺旋二聚化结构域，GARP 家族蛋白分为充当单体转录因子的成员和充当二聚体形式转录因子的成员。最近的研究表明，形成二聚体的 GARP 家族成员进一步分为 PHR1 和 NIGT1 亚家族，在磷 (P) 和氮 (N) 获取的调节中发挥着关键作用。在这篇综述中，我们对 GARP 家族蛋白进行了总体概述，并讨论了 PHR1 和 NIGT1 亚家族的几个成员如何参与协调获取 P 和 N 以响应环境营养条件的变化，同时主要关注最近的研究进展。这些发现增强了我们对 PHR1 和 NIGT1 在磷酸盐饥饿信号传导和硝酸盐信号传导中作用的了解。
