Abstract:
Floral nectar chemical composition of conventional and transgenic sweet orange trees expressing the antibacterial peptide sarcotoxin IA (Stx IA), which has been shown to efficiently inhibit in vitro growth of the bacteria responsible for citrus canker (Xanthomonas axonopodis pv. citri), is reported. The nectar contents of primary metabolites (sugars, amino acids, proteins, triacylglycerides) and of the secondary metabolites (total purine alkaloids, phenolic compounds and phytosteroids) were determined by spectrophotometric analysis. The results showed small differences in the nectar primary and secondary metabolites composition. The biochemical and biological significance and the possible effects of these variations on key citrus pollinators are discussed.
