摘要 Plant receptor-like kinases (RLKs) control the initiation, development and maintenance of symbioses with beneficial mycorrhizal fungi and nitrogen-fixing bacteria. Carbohydrate perception activates symbiosis signalling via Lysin-motif (LysM) RLKs and subsequently the common symbiosis signalling pathway. As the receptors activated are often also immune receptors in multiple species, exactly how carbohydrate identities avoid immune activation and drive symbiotic outcome is still not fully understood. This may involve the coincident detection of additional signalling molecules that provide specificity. Because of the metabolic costs of supporting symbionts, the level of symbiosis development is fine-tuned by a range of local and mobile signals that are activated by various RLKs. Beyond early, pre-contact symbiotic signalling, signal exchanges ensue throughout infection, nutrient exchange and turnover of symbiosis. Here, we review the latest understanding on plant symbiosis signalling from the perspective of RLK-mediated pathways.
