Isolated mogroside and mogrol biosynthetic pathway enzyme polypeptides useful in mogroside biosynthesis are provided. Mogroside biosynthetic pathway enzymes of the invention include squalene epoxidase (SE), epoxy hydratase (EH), cytochrome p450 (Cyp), cucurbitadienol synthase (CDS) and udp-glucosyl-transferase (UGT), Also provided are methods of producing a mogroside using the isolated mogroside and mogrol biosynthetic enzyme polypeptides, the methods comprising contacting a mogrol and/or a glycosylated mogrol (mogroside) with at least one UDP glucose glucosyl transferase (UGT) enzyme polypeptide of the invention catalyzing glucosylation of the mogrol and/or the glucosylated mogrol to produce a mogroside with an additional glucosyl moietie(s), thereby producing the mogroside. Alternatively or additionally provided is a method of synthesizing a mogrol, the method comprising contacting a mogrol precursor substrate with one or more mogrol biosynthetic pathway enzyme polypeptides as described herein catalyzing mogrol synthesis from the mogrol precursor substrate, thereby synthesizing the mogrol.

Cells comprising mogroside pathway enzymes and uses thereof

Aplant or a part thereof, the plant bearing more than 12 fruit, the fruit being seedless. Methods of generating same and breeding same are also disclosed.

Melon plants with enhanced fruit yields

Provided are isolated polynucleotides comprising a nucleic acid sequence encoding a polypeptide, wherein the polypeptide modulates acidity of a plant. Also provided are nucleic acid constructs and plant cells comprising same and methods of using same for modulating acidity of a plant.
