Abstract

This article focuses on the role of PsAMT1.2, an ammonium transporter gene from Populus simonii, in enhancing salt tolerance in poplar trees. Overexpression of PsAMT1.2 in transgenic poplars improved growth under salt stress by increasing photosynthetic efficiency, chlorophyll content, antioxidant enzyme activities, and proline accumulation, while reducing membrane lipid peroxidation. The transgenic poplars also maintained a higher potassium-to-sodium (K+/Na+) ratio, contributing to ion homeostasis under salt stress. Transcriptome analysis revealed that PsAMT1.2 regulates genes related to photosynthesis, antioxidant activity, and ion transport, providing molecular insights into its role in salt tolerance.
