Inside the plant immune circuit
The active topic is a dense research ledger of plant immunity at molecular scale. The center of gravity is the NLR immune receptor: how it senses danger, how helper and sensor proteins assemble, and how pathogens try to interrupt that assembly.
The selection repeatedly returns to the arms race between pathogen effectors and plant receptors. Papers on molecular mimicry, effector interference, and virulence targets show an editorial eye trained on mechanism rather than broad agricultural headlines.
A structural thread runs through the topic as well. Resistosomes, receptor architecture, EDS1-dependency, and the NRC immune receptor network appear as parts of a larger question: how plants convert recognition into defense with enough precision to stop disease.
