NtMYB78 enhances salt tolerance in tobacco by coordinating stress responsive transcription and lignin deposition.

NtMYB78 boosts salt tolerance in tobacco by activating stress responses and increasing lignin deposition, with overexpression lines showing improved survival under salinity.

• Why it matters: Soil salinization severely hampers plant growth and crop yields, highlighting the need for genetic strategies to enhance salt tolerance in crops.
• What they did: Researchers used overexpression and knockout tobacco lines to analyze NtMYB78's role, revealing its induction by salt stress and its regulation of genes related to stress defense, photosynthesis, and lignin biosynthesis.
• The result: NtMYB78 enhances salt tolerance by coordinating transcriptional reprogramming and physiological protection, making it a valuable target for developing salt-resistant crops.
