▶ AI Summary
The study establishes Aeschynomene evenia as a new model for dissecting legume immunity against the soilborne pathogen Aphanomyces euteiches and its interaction with Nod factor‑independent symbiosis. Transcriptomic profiling revealed thousands of differentially expressed genes involved in pathogen perception, signaling, and specialized metabolism, with overlapping signatures between defense and symbiosis pathways, and identified dual‑function kinases whose loss enhances resistance. These findings highlight A. evenia‑A. euteiches as a valuable system for investigating quantitative resistance and its crosstalk with symbiosis.
