E3 유비퀴틴 라이게이스 RHB1A와 전사인자 GRF1이 포플러에서 광합성 성장과 염 내성 간의 균형을 조절하는 조절 모듈을 형성한다.

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.
