Barley leaf discs maintained in dark accumulated a massive amount of putrescine (Put), lost chlorophyll and senescenced rapidly. At the same time RNase activity increased significantly. Exogenous spermidine (Spd) inhibited RNase activity, the loss of chlorophyll and degradation of the proteins from thylakoid membranes. Using SDS-PAGE and immunoblot analysis it was shown that spermidine was effective in the retardation of the loss of LHCPII observed in water-treated detached leaves. Analysis of PSII particles isolated from leaf fragments floated in water in the dark revealed the presence of Put, Spd and Spm. In spermidine treated leaves the level of this polyamine in photosystem II was above 5-fold higher than in control. The experimental findings obtained in this study provide evidence that applied spermidine interacts directly with thylakoid membranes so that they become more stable to degradation during senescence.

The present paper discusses the effects of α-aminooxyacetic acid (AOA) on contents of polyamines, anthocyanins, photosynthetic pigments and phenylalanine ammonia-lyase activity in seedlings of common buckwheat (Fagopyrum esculentum Moench). AOA clearly decreased light-induced formation of anthocyanins and inhibited PAL activity in buckwheat hypocotyls, although a slight stimulatory effect on anthocyanins content in buckwheat cotyledons was observed. AOA declined the contents of chlorophylls a and b, and total carotenoids in buckwheat cotyledons. The results show that AOA inhibits phenylpropanoids biosynthesis in buckwheat hypocotyls, and suppress photosynthesis in cotyledons. Moreover, the experiments show that AOA enhances the level of free putrescine in hypocotyls and the level of spermidine in buckwheat cotyledons. AOA also diminished the content of putrescine in cotyledons, but did not affect its level in buckwheat hypocotyls. AOA also substantially declined the level of cadaverine in buckwheat cotyledons, and did not affect its content in hypocotyls. Differences in effect of AOA on anthocyanins and polyamines accumulation indicate various physiological roles of the compounds in buckwheat hypocotyls and cotyledons.

Barley (Hordeum vulgare) seedlings were treated with spermidine prior to water deficit to determine whether this polyamine is able to affect the activity of superoxide dismutase - SOD (EC 1.15.1.1) responsible for hydrogen peroxide and superoxide radical level. Short-term dehydration (24h) resulted in decrease of the SOD specific activity and a distinct increase in the superoxide anion and hydrogen peroxide contents. Polyamine treatment caused a substantial reduction in the contents of these two stress-raised reactive oxygen species and there by lowered the oxidative stress in plant cells. Antioxidant system as an important component of the water-stress-protective mechanism can be changed by polyamines, able to moderate the radical scavenging system and to lessen in this way the oxidative stress

This study concerns on the influence of diamines (agmatine, putrescine) and polyamines (spermine, spermidine) upon the growth and the content of chlorophyll a and b, monosaccharides and proteins in the cells of alga Chlorella vulgaris Beijerinck (Chlorophyceae). In the experiments agmatine, putrescine, spermine and spermidine in the range of concentrations 10-6-10-3 M were used. At the concentration 10-3 M and the 1st day of cultivation, they have a toxic effect on growth of the algae. It was found that di- and polyamines used within the range of concentration 10-6-10-4 M stimulate the growth and the contents of analysed biochemical parameters in the cells of C. vulgaris. The most stimulating influence on metabolism of the alga was demonstrated by spermidine and putrescine at concentration of 10-4 M. Agmatine and spermine were characterised by a lower biological activity than spermidine and putrescine demonstrated the most stimulating influence.

A differential expression pattern of spermidine/spermine N1-acetyltransferase (SSAT), the enzyme critical to proper homeostasis of cellular polyamines, is reported in mouse kidney undergoing hyperplasia and hypertrophy. We have shown that SSAT activity and SSAT mRNA are significantly induced by antifolate CB 3717 and folate that evoke a drug-injury-dependent hyperplasia. In contrast, SSAT activity is down-regulated in the testosterone-induced hypertrophic kidney, while SSAT mRNA is positively controlled by this androgen. Catecholamine depletion evoked by reser- pine drastically decreases the folate-induced activity of «S-adenosylmethionine decar- boxylase (AdoMetDC), which limits polyamine biosynthesis, but has no effect on SSAT activity augmented by CB 3717. Our results document that the increased SSAT expression solely accompanies the proliferative response of mouse kidney, and sug­gest the importance of post-transcriptional regulation to the control of SSAT activity in both hyperplastic and hypertrophic experimental models.
