“…In higher plants, PAs are involved in a variety of developmental processes, such as floral and fruit development (Liu et al 2006a). Early work showed that exogenous application of PAs during fruit set or early fruit development increased the number and the size of the fruits that set (Evans and Malmberg 1989).…”

Polyamines (PAs) are required for cell growth and cell division in eukaryotic and prokaryotic organisms. The present study is aimed at understanding the developmental regulation of PA biosynthesis and catabolism during flower opening and early fruit development in relation to fruit size and shape. Two full-length cDNA clones coding for S-adenosyl methionine decarboxylase (SAMDC) and spermidine synthase (SPDS) homologs, key steps in the PA biosynthesis pathway, in the stone-fruit of olive (Olea europaea L.) were identified and the spatial and temporal organization of these genes were described. In olive flowers, OeSAMDC gene transcripts were highly expressed in ovary wall, placenta and ovules, while OeSPDS transcript was confined to the ovules of ovary at anthesis stage. A correlation was detected between the SAMDC enzyme activity/accumulation transcript and spermidine (Spd) and spermine (Spm) levels during flower opening, implying that the synthesis of decarboxylated SAM might be a rate-limiting step in Spd and Spm biosynthesis. OeSAMDC and OeSPDS transcripts were co-expressed in fruit mesocarp and exocarp at all developmental stages analyzed as well as in nucellus, integuments and inner epidermis tissues of fertilized ovules. In contrast, the OeSAMDC and OeSPDS genes had different expression patterns during early fruit development. The results provide novel data about localization of PA biosynthesis gene transcripts, indicating that transcript levels of PA biosynthesis genes are all highly regulated in a developmental and tissue-specific manner. The differences between the two olive cultivars in the fruit size in relation to the differences in the accumulation patterns of PAs are discussed.

“…On the 28 th day, while the highest TA content of peaches was detected in Put+ultrasound-treated fruits (0.65%), the lowest TA content was determined in ultrasound-treated fruits (0.56%). Liu et al (2006) reported that the reasons remain unclear why PAs modify soluble solutions and titratable acids. Cao et al (2010a) and Yang et al (2011) also informed that ultrasound treatment had no significant effect on TA.…”

Peach (Prunus persica [L.] Batsch) is a perishable product and its storage period may be extended by using different postharvest methods. For this purpose, peaches harvested at the commercial ripening stage were treated with individual and combined effects of putrescine (1 mM) and ultrasonic treatment (32 kHz for 10 min); postharvest storage quality of peach fruit was evaluated during storage at 0-1 °C for 28 d. Quality characteristics such as weight loss, fruit firmness, respiration rate, total sugar, total soluble solid content, titratable acidity, chilling injury, and decay rate were determined at the beginning and during the storage period at 1-wk intervals. The result showed that individual and combined effects of putrescine and ultrasonic treatment, when compared to control fruits, could increase peach fruit postharvest life by inducing resistance to different diseases and chilling injury with no noticeable effect on fruit quality attributes such as weight loss, total soluble solids, and total sugar. At the same time, a combined putrescine and ultrasound treatment was found to be more effective than other treatments in decreasing respiration rate and maintaining firmness and acidity. Peach storability could be extended with a combined putrescine and ultrasound treatment because it delays the ripening processes.

“…Polyamines have long been known to play an important role in the regulation of various plant developmental phenomena including flowering and fruiting in a number of plant species (Alcázar et al, 2005;Kakkar and Rai, 1993;Kaur-Sawhney et al, 2003;Liu et al, 2006;Wang and Kao, 2006;Yamasaki and Cohen, 2006;Ziosi et al, 2006). In olive cultivars, spray application of putrescine was reported to increase fruit set and yield (Iannotta et al, 1996;Rugini and Mencuccini, 1985).…”

Different Flower-Inducing Conditions Elicit Different Responses for Free Polyamine Levels in Olive (<i>Olea europaea</i>) Leaves

In various plant species, polyamines have been implicated in regulating developmental phenomena as well as responses to environmental stimuli. The role of polyamines in regulating developmental phenomena in olive trees, such as flowering, is poorly understood, although seasonal changes and temperature effects on polyamine levels in olive trees have been reported. In this study, levels of free polyamines (putrescine, spermine, and spermidine) in the leaves of trees kept under non-inducing conditions were compared with polyamine levels in trees that were induced to flower under chilling and non-chilling conditions. Putrescine and spermine levels were much higher in leaves kept under inductive chilling conditions compared to control trees kept vegetative, but such increased levels of polyamines did not occur in trees that were induced to flower under non-chilling conditions. These results clearly differentiated between the effects of temperature versus the effect of developmental change on free polyamine levels in olive leaves. The results show that changes in free polyamine levels in leaves have little relevance to flowering in olives. Free polyamine levels within auxiliary buds increased when vegetative buds transformed into flowering buds and then declined when buds developed into flowers. Compared to floral buds, immature and mature fruits contained much smaller amounts of polyamines.
