BACKGROUND Polyamines are small polycationic molecules found ubiquitously in all organisms and function in a wide variety of biological processes. In the past decade, molecular and genetic studies using mutants and transgenic plants with an altered activity of enzymes involved in polyamine biosynthesis have contributed much to a better understanding of the biological functions of polyamines in plants. POSSIBLE ROLES Spermidine is essential for survival of Arabidopsis embryos. One of the… CONTINUE READING
