In this review, we synthesise current knowledge on how carbohydrate dynamics coordinate metabolism, signalling, and structural responses to shape plant resistance against both pathogens and herbivores. We highlight how spatial and temporal regulation of sugar transport, mediated by SWEET, SUT\/SUC, and STP transporters, controls carbon availability at plant\u2010heterotroph interfaces, while sucrose\u2010cleaving enzymes such as invertases and sucrose synthase modulate local sugar composition to support defence metabolism or restrict nutrient access to attackers. Beyond metabolic functions, sugars act as signalling molecules that regulate immune responses through complex sensing and energy\u2010signalling networks. Central to this framework are trehalose\u20106\u2010phosphate and the antagonistic kinases SnRK1 and TOR, which integrate carbon status with growth\u2010defence decisions. These pathways are closely interconnected with phytohormone signalling, forming a bidirectional regulatory network that enables plants to tailor defence responses according to attacker lifestyle, including biotrophic and necrotrophic pathogens as well as sap\u2010sucking and chewing herbivores. In parallel, carbohydrate\u2010based cell wall remodelling reinforces physical barriers and generates damage\u2010associated molecular patterns that activate immune signalling. We further discuss how carbohydrates contribute to immune priming, enhancing resistance while minimising fitness costs. Collectively, this review highlights sugars as central regulators that coordinate carbon allocation with immune activation across multiple biological scales, providing promising opportunities for developing sustainable strategies to enhance crop resistance against pathogens and herbivores.<\/jats:p>","DOI":"10.1111\/pce.70817","type":"journal-article","created":{"date-parts":[[2026,8,19]],"date-time":"2026-08-19T07:26:41Z","timestamp":1787124401000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Sugars
