<i>Hsp101-1</i> Orchestrates Thermotolerance in Rice via Pre-Activated Transcriptional Networks and Modular Cross-Tissue Coordination.

ABSTRACT: Background/Objectives: Rice production faces threats from rising temperatures, demanding thermotolerant varieties. This study characterizes transcriptomic dynamics and identifies Hsp101-1 (heat shock protein 101-1)-associated gene regulatory modules in rice under reproductive-stage heat stress. Methods: Transcriptomics and WGCNA (weighted gene co-expression network analysis) were conducted in flag leaves and spikelets for wild-type (WT) and Hsp101-1-overexpressing (OE) lines under 40 °C stress at six time points (0-24 h) to reveal the change in gene expressions. Results: The number of DEGs (differentially expressed genes) revealed substantial pre-existing differences in WT and OE lines. Pre treatment, OE flag leaves showed 545 upregulated and 676 d
