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.

Implication

Reveals improved drought-heat stress tolerance in Populus, suggesting a novel regulatory model.

Abstract

• We dissected the molecular mechanism of drought-heat stress in poplar. • Integrating TO-GCN and expression pattern analyses, we detected PagMBF1C as a key gene in combined stresses. • A module of PagMBF1C‑PagWRKY75 regulating drought-heat stress is identified in poplar.
