Fig. 1.

Diagram of experimental design and sampling points. 0-6 h was the first dehydration treatment (FD), 6 h-12 h was the first rehydration treatment (FR), 12 h-18 h was the second dehydration treatment (SD), 18 h-24 h was the second rehydration treatment (SR). All periods of dehydration stress are marked in red, while submerged (rehydration) periods are marked in green. The blue circles represent sampling time points, the orange dotted line represents the presumed expression pattern of dehydration-related genes
