摘要：

Plants must adapt to their environment and require mechanisms for sensing their surroundings and responding appropriately. An expanded family of more than 200 leucine-rich repeat (LRR) receptor kinases (LRR-RKs) transduces fluctuating and often contradictory signals from the environment into changes in nuclear gene expression. Two LRR-RKs, BRASSINOSTEROID INSENSITIVE 1 (BRI1) a steroid receptor, and FLAGELLIN SENSITIVE 2 (FLS2), an innate immune receptor that recognizes bacterial flagellin, act cooperatively to partition necessary growth-defense trade-offs. BRI1 and FLS2 share common signaling components and slightly different activation mechanisms. BRI1 and FLS2 are paradigms for understanding the signaling mechanisms of LRR-containing receptors in plants.
