Figure 4: Expression patterns of osmotic, cold, and salt tolerance genes involved in ABA-dependent and ABA-independent signaling network.

(A) Generalized model of the ABA-dependent and ABA-independent signaling network. Osmotic (B), cold (C), and salt (D) tolerance genes associated with ABA signaling network were identified from the DE genes. Log2 based RPKM value was used to create the heat map. The scale represents the relative signal intensity of RPKM values. PYL, Abscisic acid receptor; PP2C, Protein phosphatase 2 C; SnRK2, Osmotic stress/abscisic acid-activated protein kinase; ABF, ABRE binding factors; MYB, Myb transcription factor; MYC, Myc transcription factor; NAC, Nac transcription factor; DREB, Dehydration-responsive element-binding protein.
