Plant hormone signal transduction pathway after 1 day of waterlogging stress. (A) The number of hormone-signal-related DEGs changes in bananas under waterlogging stress. The DEGs were involved in (B) the ethylene biosynthetic pathway and (C) carbon metabolism. The yellow box highlights the glycolysis pathway, leading to the ethanol fermentation in the purple box, and lastly, the blue box contains genes involved in the tricarboxylic acid (TCA) cycle. The arrows indicate activation of the gene, while the blunt end represents inhibition of the gene. The red cross indicates the inactivity of the EIN3 pathway that leads to the activation of ERF TFs. The numbers in parentheses correspond to the number of upregulated (red) and downregulated genes (blue).
