Inside the plant immune system
The defining thread is the immune receptor as a molecular machine. The feed returns again and again to NLR architecture, helper and sensor relationships, and the structural rules that let plants turn recognition into defense.
Pathogens appear here as active engineers of infection, not as background threats. Effectors block resistosome assembly, suppress immunity, target host trafficking, and reveal the weak points that plant immunity must protect.
The applied horizon is never far away. Papers on barley, wheat, potato, soybean, rice, citrus, and other crops show a steady interest in how mechanistic knowledge can become resistance engineering and disease control.
The topic also watches the cell biology of infection: autophagy, organelle trafficking, extracellular vesicles, plasmodesmata, and RNA-based defenses. That breadth gives the feed the feel of a lab-wide literature radar rather than a narrow bibliography.
