Phytohormones pathways. DEGs involved in the auxin and ABA signaling pathways in both grapevine rootstocks. (A) Auxin synthesis, transport, sensing, and transcription factors pathway, and (B) Abscisic acid synthesis, transport, signaling, and transcription factors pathway. The absolute values of log₂FC ≥ 2 and FDR < 0.05 were used as thresholds to identify statistically significant DEGs. Color of the box indicates up (red) and down (blue)-regulated genes. / - not expressed, NS - not statistically significant, F1:0 - Fercal N1A0 (-Fe vs. + Fe), C1:0–3309 C N1A0 (-Fe vs. + Fe), F1:1 - Fercal N1A1 (-Fe vs. + Fe), C1:1–3309 C N1A1 (-Fe vs. + Fe). The detailed DEGs are listed in supplementary Table S6
