Diagram of a wheat plant cell cross-section. On the left side of the cell, the TaMAKK2-TaMAPK6 kinase cascade phosphorylates the core immune regulator TaSGT1 and promotes its nuclear entry, contributing to resistance to stripe rust; on the right, an effector from the fungal pathogen that causes stripe rust targets and blocks this process.

Transcription factor bHLH25 plays a dual role in #plant defense.
Oxidized, it boosts #lignin production to strengthen #cell walls against #pathogens.
Non-oxidized, it activates #phytoalexins to inhibit pathogen growth.
Together, these functions may help us create disease-resistant #crops without yield loss.
