Regulatory network of cold (A), heat (B), salt (C) and drought (D) stresses in potatoes. A The upregulated ICE1 and ADC1 promote transcriptional activity of StCBFs under cold stress. MAPKs kinase activities are activated to promote StCBFs and SLD2 expression. B Under heat stress, induced SES and StTOC1 downregulate StSP6A. Heat suppresses the transcriptions of DOG1 and SLP while promotes that of StHsps. C Under salt stress, ABA plays a crucial role by upregulating DREBs. BRs, StDWF4 and StBBX24 promotes salt stress-related genes and enhances resistance to salt. D Under drought, ABA and MAPKs are induced and ABA activates SnRKs kinase activity. Transcription factors (e.g., NF-Ys and MYBs), StPIP1, StDRO1, and StCIPKs are also involved in drought response
