Resumo: Plants have adapted a variety of strategies to rapidly messages and mitigate the impact of biotic and abiotic factors from their surroundings. Communication between plants occurs when a plant, naturally or under stress conditions, emits a signal that is perceived by a neighboring receiving plant. The recognition or perception of these signals induces modifications of plant metabolism and physiology, including modulation of the plant defense system. These signals can be transferred between plants via wired- and wireless communications. Wired communications involve direct contact between plants, as signals transfers mediated by mycorrhizal hyphae, parasitic plant stems, or through rhizome and stolon. Wireless communications involve plant volatile emissions and root exudates which enable inter-plant signaling without physical contact. In this seminar, an overview will be approached of the wired- and wireless mechanisms involved in plant–plant interactions and how it can influence the defense modulation against pathogens in neighboring plants.
