Physiological response of sunflower (Helianthus annuus L.) to exogenous arginine and putrescine
treatments under salinity stress.
In Araucaria angustifolia, high levels of putrescine
and spermidine were observed in pre-cotyledonary somatic embryos, with subsequent decrease after the cotyledons formation (Astarita, Handro, & Floh, 2003).
Treatment with different concentration of apigenin resulted in an acceleration of cellular polyamine catabolism in a dose dependent manner, which was manifested in the increase of putrescine
and decrease of spermine and spermidine levels.
Among the five amines investigated, putrescine
was prevalent in all types of wines.
Solutions of putrescine
at 0.0 (with distilled water), 1, 2 and 3 mM were sprayed to run-off (approximately 500 mL per plant), about two weeks before flowers harvest.
Acute and subacute toxicity of tyramine, spermidine, spermine, putrescine
and cadaverine in rats.
More than 93% of all strains did not utilize also i-erythritol, L-rhamnose, D-sorbitol, D-galactonic acid lactone, D-gluconic acid, [gamma]-hydroxybutyric acid, p-hydroxy phenylacetic acid, [alpha]-keto-valeric acid, quinic acid, saccharic acid, L-leucine, L-ornithine, L-phenylalanine, L-pyroglutamic acid, D-serine, thymidine, phenylethylamine, and putrescine
and utilized [alpha]-D-glucose, L-fucose, and sucrose.
SAM is also a precursor for the biosynthesis of polyamines which are involved in response to abiotic stresses ; in particular the polyamine spermine which is synthesized from putrescine
via two steps using SAM was shown to have a protective role against drought stress .
amazonensis indicated modified uptake of spermidine and putrescine
in PMD-resistant parasites.
Metabolic relationships of putrescine

Anchovies are associated with scombroid-poisoning due to biogenic amine contents such as histamine, putrescine
