overexpression of yeast spermidine synthase impacts ripening, senescence and decay symptoms in tomato. Constitutive expression of ySpdSyn enhances intracellular levels of Spd in the leaf, and transiently during fruit development, whereas E8-ySpdSyn expression leads to Spd accumulation early and transiently during fruit ripening. The ySpdSyn transgenic fruits have a longer shelf life, reduced shriveling and delayed decay symptom development in comparison with the wild-type fruits, crop maturity is delayed in a CaMV35S-ySpdSyn genotype, with fruits accumulating higher levels of the antioxidant lycopene. Notably, whole-plant senescence in the transgenic plants is also delayed compared with wild-type plants, phenotypes, overview |

| 2.5.1.16 | physiological function |
in vitro shoots of a transgenic European pear overexpressing apple spermidine synthase (MdSPDS1) and the wild-type are subjected to long-term stress for 0.03 mM AlCl3. SPDS expression level and spermidine titer of the transgenic line are substantially higher than those of wild-type when subjected to long-term Al stress. Transgenic line show showed higher tolerance to Al stress, and its ameliorated performance is closely correlated to polyamine accumulation, especially, to a higher spermidine titer chiefly via alleviating oxidative status as well as by affecting mineral element balance |

in zebrafish spermidine, but not spermine, is essential for early development, organogenesis and colour pattern formation |

| 2.5.1.16 | physiological function |
PgSPD expression is slightly induced by mannitol and CuSO4. Salt, chilling, abscisic acid and jasmonic acid trigger a significant induction of PgSPD expression within 12-24 h post-treatment, especially PgSPD is prominently induced by salt (41.5fold) |

| 2.5.1.16 | physiological function |
spermidine synthase catalyses the formation of spermidine, which is an essential polyamine, spermidine is also a precursor to further polyamines, such as spermine and thermospermine, most of which contribute to tolerance against drought and salinity in plants. Thermospermine is indispensible for vascular tissue growth |

| 2.5.1.16 | physiological function |
spermidine synthhase is responsible for spermdine synthesis from putrescine, the polyamines putrescine, spermidine and spermine are cationic molecules that are found in all eukaryotic cells and are clearly essential to growth and development |
