Sugars are involved in many metabolic and signaling pathways in plants. Sugar signals may also contribute to immune responses against pathogens and probably function as priming molecules leading to PAMP-triggered immunity (PTI) and effector-triggered immunity (ETI) in plants. These putative roles also greatly depend on coordinated relationships with hormones and the light status in an intricate network. Although evidences in favor of sugar-mediated plant immunity are accumulating, more in-depth fundamental research is required to unravel the sugar signaling pathways involved. This might pave the way to use biodegradable sugar-(like) compounds to counteract plant diseases, as cheaper and safer alternatives for toxic agrochemicals.
