StWRKY40 and StMAPK3 positively regulate drought tolerance in potato (Solanum tuberosum L.) via mediating osmotic adjustment, photosynthetic capacity, and antioxidant defense.
Potato (Solanum tuberosum L.) is a vital global food crop whose yield is severely constrained by drought stress. Both WRKY transcription factors (TFs) and the mitogen-activated protein kinase (MAPK) signaling pathway have been established as key components of plant stress response networks. However, the specific molecu...
