The PagMBF1C-PagWRKY75 regulatory model improves combined drought-heat stress tolerance in Populus

Key Points

• This research aims to understand how to improve tolerance to combined drought and heat stress in poplar trees.
• Analyzed the molecular mechanisms of drought-heat stress in poplar using TO-GCN and expression pattern analyses.
• Identified PagMBF1C as a key gene involved in regulating response to combined stresses.
• The study found that PagMBF1C positively regulates drought-heat stress tolerance in Populus trees.
• A new regulatory module consisting of PagMBF1C-PagWRKY75 was characterized for its role in stress response.
