Abstract
Plant intracellular nucleotide-binding domain leucine-rich repeat (NLR) receptors play crucial roles in immune responses against pathogens. How diverse NLRs recognize different pathogen effectors remains a significant question. A recent study published in Nature uncovered how pepper NLR Tsw detects phytohormone receptors' interference caused by tomato spotted wilt virus (TSWV) effector, triggering a robust immune response, showcasing a new manner of NLR guarding.
