ABSTRACT
Sugarcane plants were developed that produce the sucrose isomers trehalulose and isomaltulose through expression of a vacuole-targeted trehalulose synthase modified from the gene in 'Pseudomonas mesoacidophila MX-45' and controlled by the maize ubiquitin (Ubi-1) promoter. Trehalulose concentration in juice increased with internode maturity, reaching about 600 mM, with near-complete conversion of sucrose in the most mature internodes. Plants remained vigorous, and trehalulose production in selected lines was retained over multiple vegetative generations under glasshouse and field conditions.
