摘要 SENSITIVE TO PROTON RHIZOTOXICITY 1 (STOP1) is a master transcription factor (TF) that regulates genes encoding proteins critical for cellular pH homeostasis. STOP1 also causes pleiotropic effects in both roots and shoots associated with various stress tolerances. STOP1-regulated genes in roots synergistically confer tolerance to coexisting stress factors in acid soil, and root-architecture remodeling for superior phosphorus acquisition. Additionally, STOP1 confers salt tolerance to roots under low-potassium conditions. By contrast, STOP1 antagonistically functions in shoots to promote hypoxia tolerance but to suppress drought tolerance. In this review, we discuss how these synergetic- and antagonistic-pleiotropic effects indicate that STOP1 is a central hub of stress regulation and that the harmonization of STOP1-regulated traits is essential for plant adaptation to various environments.
