Figure 5.

Clustered heatmaps and dendrograms of the normalized log₂ fold change (FC) visualizing the expression of drought-related DEGs in Icatu and CL153 plants grown under MWD or SWD in comparison with WW plants grown under aCO₂ or eCO₂, at 25/20 °C (day/night). Values were scaled by row using Z-scores. Hot colors represent up-regulated DEGs, and cold colors represent down-regulated DEGs. Column color labels groups comparisons by water treatments (yellow/orange: MWD; light blue/dark blue: SWD; light colors represent aCO₂; dark colors represent eCO₂). An absence of data in CL153 plants under MWD-eCO₂ indicates the absence of significant DEGs.
