E3泛素连接酶RHB1A与转录因子GRF1形成调控模块，协调杨树中光合生长与盐胁迫耐受性的权衡

Key Points

• This research aims to understand how the interaction between GRF1 and RHB1A regulates the balance between growth and salt stress responses in poplar.
• Identified GRF1 and RHB1A in transgenic poplar lines through multi-omics approaches.
• Demonstrated the role of RHB1A in ubiquitinating and degrading GRF1.
• Analyzed the transcriptional activity of GRF1 under different stress conditions.
• GRF1 promotes photosynthesis-related genes under normal conditions.
• Salt stress increases RHB1A levels, leading to reduced GRF1 and altered gene expression.
• Establishment of a GRF1-RHB1A module that regulates the trade-off between growth enhancement and salt tolerance.
