“…Our data are more easily compared to fruits in which the cell division phase is followed by a period of cell extension. A correlation has been shown between a high activity of ornithine and arginine decarboxylase as well as high putrescine levels and rapid cell proliferation in the early stages of fruit growth in tomato by Heimer et al (1979) and Teitel et al (1985), suggesting their direct involvement in cell division. In addition, our data on high polyamine levels a few days after bloom, and their subsequent decrease, are in agreement with their findings as well as those obtained by Slocum and Galston (1985) during tobacco ovary development.…”

The distribution of free and bound polyamines was investigated from blooming until harvest on flower, fruitlets and fruits of Malus domestica Borkh cv. Golden Delicious, Relationships between polyamines and fruit set and growth were also investigated. The level of free polyamines was high only during the first weeks after full bloom and then decreased gradually. The amount of bound trichloroacetic acid‐insoluble polyamines was much higher than free polyamines. Bound spermine in particular showed a high value for almost 40 days after full bloom, while spermidine and putrescine were no longer detectable even a few days after full bloom. In relation to fruit set, it was possible to observe that abscission peaks took place when free polyamine levels were low or decreasing. Insofar as fruit growth is concerned, the most substantial variations in polyamine levels occurred very early in the season when fruit dry weight and protein amount were also changing rapidly and fruit diameter was almost impossible to measure.

“…The importance of polyamines in flowering and fruit ripening has been described (Kakkar and Rai 1993), and the changes in free polyamine levels during the fruit growth and ripening have been investigated in a wide variety of plants such as tomato (Teitel et al 1985; Saftner and Baldi 1990), pepper (Serrano et al 1995), pear (Toumadje and Richardson 1988) and eggplant (Rodriguez et al 1999). Most of these studies report fundamentally a similar observation with cucumber fruit in the present study, that is, a decrease in polyamine content during the process of fruit development and ripening (Fig.…”

Polyamine compositions of various organs from hydroponically cultivated cucumber plants (Cucumis sativus L. cv. Sharp-1) and factors affecting the leaf polyamine content were examined. Diamine putrescine was found most abundantly in the root, while a relatively large amount of spermine was detected in the reproductive organs such as the immature fruit and the calyx (+stamen). Spermidine was present at the highest level in rapidly growing tissues such as newly expanded leaf and fruit at an early developing stage, implying the possible involvement of spermidine in the growth and development of these young tissues. Polyamine content of cucumber leaves changed during the day. Especially, the putrescine content of upper leaves showed a striking decrease from the morning to the night. Alterations of leaf Ca or Mg content did not significantly affect leaf polyamine composition. On the other hand, abnormal cucumber leaves showed altered polyamine composition. Yellowing of the leaf intervein resulted in a striking decrease in spermidine content without a significant change in putrescine and spermine content. By contrast, the leaves infected with the phytopathogen, powdery mildew, showed decreased putrescine and increased spermine content in response to the degree of fungi infection. The possible usefulness of polyamines as a diagnostic marker of plant development and physiological disorder is discussed.

“…Several papers from the Mizrahi group in Beersheba (Israel) (Heimer et al. 1979;Teitel et al. 1985) and PAS are both derived from SAM and tend to have opposite effects on fruit ripening, it is natural to think of the fate of SAM as determining the future of the fruit.…”

Plant Polyamines in Reproductive Activity and Response to Abiotic Stress*

et al. 1997

Abstmct:In this review we will focus on two areas in which the accumulated evidence for a critical physiological role of polyamines is becoming compelling, i.e. reproductive activity and response to abiotic stress. Regarding reproductive behavior, it seems clear that polyamines are members of the array of internal compounds required for flower initiation, normal floral organ morphogenesis. fruit growth and fruit ripening in particular plant species. Abiotic stresses such as osmotic stress can "turn on" arginine decarboxylase (ADC) genes, resulting in a rapid increase in their mRNA levels. Localization of ADC enzyme in the chloroplast suggests a role of PAS in the maintenance of photosynthetic activity during senescence responses induced by osmotic stress. We envisage that the use of transgenic plants and improved molecular probes will resolve in the near future the physiological significance of stress-induced changes in PA metabolism as well as the role of these compounds in reproductive activity.
