The development of genetically modified (GM) crops speeds up the obtainment of novel varieties with improved agronomic characteristics. However, the risk evaluation of the use of GMs is mandatory before their release in the market. In this paper, an untargeted and comprehensive nuclear magnetic resonance-based metabolomic study was carried out on the peel and flesh of a transgenic lemon clone (E23) expressing the chit42 gene and exhibiting an increased tolerance to some pathogenic fungi and on its wild type. Results highlighted a substantial equivalence of the metabolomics profile of the transgenic clone compared to the wild type. In addition, an enhanced response of the E23 clone toward fungal pathogens affecting the postharvest management in lemon was evidenced. These results confirm the potential of genetic engineering for the punctual modification of specific agronomic traits without altering the whole pattern of metabolites and open new perspectives for a more sustainable and effective management of specific postharvest diseases in citrus.
