Sustaining energy homeostasis is crucial to every living being. To balance energy supply and demand, plants make use of an evolutionarily conserved management system consisting of two counteracting kinases, TOR (TARGET OF RAPAMYCIN) and SnRK1 (Snf1-RELATED PROTEIN KINASE 1). SnRK1 is involved in reorganizing enzymatic and transcriptional responses to survive energy-limiting conditions. Recently, members of the bZIP (basic leucine zipper) transcription factor family have been established as SnRK1 downstream mediators. We review here current knowledge on the functional impact of these group C and S₁ bZIPs, and analyze their regulation by environmental and endogenous cues. Given their specific homo- and heterodimerization, the so-called C/S₁ bZIP network is proposed to act as a signaling hub that coordinates plant development and stress responses.

维持能量稳态对每个生物至关重要。为了平衡能源供需，植物利用了进化上保守的管理系统，该系统由两种抵消激酶组成，即TOR（雷帕霉素的靶标）和SnRK1（Snf1相关蛋白激酶1）。SnRK1参与重组酶和转录反应以生存能量限制条件。最近，bZIP（碱性亮氨酸拉链）转录因子家族的成员已被确定为SnRK1下游介体。我们在这里回顾有关这些C和S ₁ bZIPs功能影响的最新知识，并分析它们对环境和内源性信号的调节作用。鉴于其特定的均二聚和异二聚，所谓的C / S ₁ 建议将bZIP网络用作协调植物发育和胁迫响应的信号枢纽。
