“…For instance, changes in free polyamine (putrescine, spermidine, and spermine) metabolism have been correlated with cell division (reviewed in 10 and 13), responses to stress (36), responses to hormones (7), with rhizogenesis (4, 5), and with floral development (14,24). In tobacco the aromatic amides are implicated in development (24,25).…”

Floral induction in plants is a paradigm for signal perception, transduction, and physiological response. The introduction of root-inducing, left-hand transferred DNA (Ri T-DNA) into the genomes of several plants results in modifications of flowering (D Tepfer [1984] Cell 47: 959-967), including a delay in flowering in tobacco (Nicotiana tabacum). Conjugated polyamines are markers for flowering in numerous species of plants. In tobacco their accumulation is correlated with the onset of flowering (F Cabanne et al. [1981] Physiol Plant 53: 399-404). Using tobacco, we have explored the possibility of a correlation between the expression of Ri TL-DNA and changes in polyamine metabolism. We made use of two levels of phenotypic change, designated T and T', that retard flowering by 5 to 10 and 15 to 20 days, respectively. We show that delay in flowering is correlated with a reduction in polyamine accumulation and with a delay in appearance of conjugated polyamines, and we propose that genes carried by the Ri TL-DNA intervene either directly in polyamine metabolism or that polyamine metabolism is closely linked to direct effects of Ri T-DNA expression.

“…High concentrations of PAs and their conjugates in sex organs also have been reported in other cases. In Nicotiana, Put was the major amine, and the stamens and gynoecium contained high levels of Put and Spd (22). In Phaseolus vulgaris also, the pistils contained the highest PA levels and enzyme activities among the various organs (21).…”

Polyamines and Flower Development in the Male Sterile Stamenless-2 Mutant of Tomato (Lycopersicon esculentum Mill.)

The levels of free putrescine, spermidine, and spermine, and the activities of ornithine decarboxylase and s-adenosylmethionine decarboxylase were determined in the floral organs of the normal and a male sterile stamenless-2 (sl-2/sl-2) mutant of tomato (Lycopersicon esculentum Mill.). Under the intermediate temperature regime, all mutant floral organs possessed significantly higher levels of polyamines and enzyme activities than their normal counterparts. In the low temperature-reverted mutant stamens, the polyamine levels and the activity of PA biosynthetic enzymes were not significantly different from the normal. It is suggested that the abnormal stamen development in the sl-2/sI-2 mutant is, in part, related to elevated levels of endogenous PAs.The diamine putrescine and the PAs3 Spd and Spm are probably of ubiquitous occurrence in plants and appear to play an important role in plant growth and development (6,10,29,30). Changes in PA levels and activities of PA biosynthetic enzymes have been implicated in a variety of plant growth processes such as breaking of dormancy (2), seed germination (31), fruit development (5, 28), somatic embryogenesis (7), pollen embryogenesis (13), adventitious root formation (9), delay of senescence (1), and adaptation to stress (10).The PAs also appear to be involved in the flowering processes of plants, i.e. the induction of flowering (4,12)

“…Plus particulièrement, la présence de certaines polyamines chez le tabac semble être liée à l'état floral, et cela juste après l'induction florale (Cabanne et al, 1977(Cabanne et al, , 1981.

(Pseudotsuga menziesii) after the transition from vegetative development to sexual development. After methanolic extraction and dansylation, polyamines (putrescina, spermidine, spermine) of shoots and buds of Douglas fir (Pseudotsuga menziesii) were separated using reverse phase high performance liquid chromatography (HPLC). They were quantified by fluorescence detection (fig 1). On plant material collected in fall, free polyamine levels were measured in morphologically distinct vegetative, male and female buds of ramets of one clone (1101) and in shoots (needles, stem, and buds) bearing only vegetative buds or vegetative as well as male and female buds of ramets of two clones (1101 and 1200). The distribution of polyamines was different between sexual and vegetative buds. Putrescine was the dominant polyamine in vegetative buds, while spermidine predominated in floral buds (fig 3). The highest concentration of spermidine was observed in male buds. Furthermore, spermine was only found in the sexual buds (fig 3). All polyamines also increased in the shoots bearing sexual buds (fig 4) compared to shoots with only vegetative buds. In general, the spermidine level was higher in buds than in shoots. Finally, the ratio between putrescine and spermidine in sexual buds as well as in shoots bearing these kinds of buds was much lower than in vegetative organs (tables / and II). The possibility of using these polyamine contents as physiological markers of sexual differentiation is discussed.
