Abstract: Edible fruit, seed and vegetables of transgenic plants modified to produce a sweetening protein such as monellin or thaumatin are useful in preparing food compositions which have enhanced sweetness improved flavor. Expression systems for the genes encoding sweetening proteins compatible with plant systems and designed to enhance the production of these proteins in the edible portions of plants, and methods for producing sweetened fruit, seeds and vegetables are described.

Abstract: Single-chain analogs of the naturally occurring two-chain peptide monellin retain the sweetening properties of the natural protein and are stable under conditions which would otherwise destabilize the native peptide. A covalent linkage joins peptides corresponding to portions of the A and B chains of the naturally occurring protein.
