Integrated transcriptomic and metabolomic analyses uncover the key pathways of Limonium bicolor in response to salt stress.

ABSTRACT: Salinity significantly inhibits plant growth and development. While the recretohalophyte Limonium bicolor can reduce its ion content by secreting salt, the metabolic pathways it employs to adapt to high salt stress remain unclear. This study aims to unravel this enigma through integrated transcriptomic and metabolomic analyses of L. bicolor under salt stress conditions. The results showed that compared to the control (S0), low salt treatment (S1) led to a significant increase in plant growth, photosynthesis efficiency and antioxidant enzyme activity but caused no significant changes in organic soluble substance and ROS contents. However, high salt treatments (S3 and S4) led to a significant decrease in plant growth, photosynthesis efficiency and antioxidant enzyme activity, accompanied by
