Transcriptomic analysis reveals the role of the molybdate transporter2 in mediating nitrate stress tolerance in tomato seedlings
The SlMOT2 gene confers nitrate stress tolerance in tomato plants, likely through the following molecular mechanisms: (1) enhancing the biosynthesis of antioxidant compounds to improve reactive oxygen species (ROS)-scavenging capacity and maintain photosynthetic efficiency;(2) activating plant hormone signaling transduction pathways to potentiate stress responses; (3) promoting sulfate uptake to rebalance excess nitrogen in planta, thereby establishing a new nitrogen-sulfur homeostasis. These findings establish a theoretical framework for improving nitrate stress resistance during tomato cultivation.
