Engineered polyamine accumulation in tomato enhances phytonutrient content, juice quality, and vine life.

Abstract:

Polyamines, ubiquitous organic aliphatic cations, have been implicated in a myriad of physiological and developmental processes in many organisms, but their in vivo functions remain to be determined. We expressed a yeast S-adenosylmethionine decarboxylase gene (ySAMdc; Spe2) fused with a ripening-inducible E8 promoter to specifically increase levels of the polyamines spermidine and spermine in tomato fruit during ripening. Independent transgenic plants and their segregating lines were evaluat...
