“…The hydroxycinnamoyl substituants of spermidine can be coumaroyl, caffeoyl, feruloyl, hydroxyferuloyl, or sinapoyl acyl groups, and mono-, di-, and trisubstituted hydroxycinnamoyl spermidine conjugates have been reported from many plant species (Bienz et al, 2005). They have been identified from flowers and pollen of a wide range of plants, including species in the Acanthaceae (Werner et al, 1995), Asteraceae (Aribaud and Martin-Tanguy, 1994), Brassicaceae (Havelange et al, 1996), Betulaceae, Fagaceae, Juglandaceae (Meurer et al, 1986;Meurer et al, 1988;Bokern et al, 1995), Rosaceae (Strack et al, 1990;Tarenghi and Martin-Tanguy, 1995), and Solanaceae (Leubnermetzger and Amrhein, 1993;Kang and Back, 2006). Among cereals, 4-coumaroyltryptamine and feruloyltryptamine have been identified in maize (Zea mays), while avenanthramides (substituted N-cinnamoylanthranilates) have been isolated from oat (Avena sativa) (Collins, 1989).…”

Hydroxycinnamic acid amides are a class of secondary metabolites distributed widely in plants. We have identified two sinapoyl spermidine derivatives, N-((4′-O-glycosyl)-sinapoyl),N′-sinapoylspermidine and N,N′-disinapoylspermidine, which comprise the two major polyamine conjugates that accumulate in Arabidopsis thaliana seed. Using metabolic profiling of knockout mutants to elucidate the functions of members of the BAHD acyltransferase family in Arabidopsis, we have also identified two genes encoding spermidine disinapoyl transferase (SDT) and spermidine dicoumaroyl transferase (SCT) activities. At2g23510, which is expressed mainly in seeds, encodes a spermidine sinapoyl CoA acyltransferase (SDT) that is required for the production of disinapoyl spermidine and its glucoside in Arabidopsis seed. The structurally related BAHD enzyme encoded by At2g25150 is expressed specifically in roots and has spermidine coumaroyl CoA acyltransferase (SCT) activity both in vitro and in vivo.

“…It has been shown in some work that different polyamine concentrations were found in the sterile and fertile organs. Correlation between polyamine and male sterility/fertility has been established in some plants, the sterile lines containing less polyamine than the fertile lines or the corresponding maintainer line, as is revealed in chrysanthemum 3 , stem mustard 29 , tobacco 42 , maize 46,47 , Araceae species 63 , and tomato 65,66 . Therefore, exogenously applied polyamine can partially restore the fertility of the sterile line, whereas fertility of the maintaining line can be decreased by the inhibitor.…”

“…Secondly, utilization of polyamine biosynthetic enzyme inhibitors prevented flowering, which was resumed when the inhibitors were absent or when polyamines were added exogenously. Much work has been carried out using inhibitors in order to probe the relationship between polyamines and floral development 2,3,20,34,77,82 . For instance, methylglyoxal bis(guanylhydrazone) (MGBG), an inhibitor of SAMDC, caused strong inhibition of flowering in Spirodela punctata, whereas the inhibitory effect was abolished by applying Spd exogenously 20 .…”

Polyamines, including putrescine (Put), spermidine (Spd) and spermine (Spm), are polycationic compounds of low molecular weight that are widely distributed in living organisms. They are implicated in a variety of plant processes, such as floral and fruit development. In addition, correlation between polyamines and flower gender or fertility is reported in some plant species. Since polyamines, especially Spd and Spm share a common precursor, S-adenosylmethionine (SAM), with ethylene, they demonstrated competitive effects on functions in fruit development and ripening in many plants. Exogenous polyamines have been employed to regulate floral and fruit development and ripening in a lot of plants. Besides, polyamines have shown their potential for postharvest fruit management. Therefore, in this review, we focused on the involvement of polyamines in floral and fruit development along with perspectives of polyamine research.

“…The recent discovery that the silencing of the S-adenosylmethionine decarboxylase (SAMDC), which is involved in the PA biosynthetic pathway in the tapetal tissue of tomato flowers, results in male sterility [ 94 ], underlines the importance of SAMDC and PAs in pollen development as well. A role for polyamines in male flower sterility/fertility was also hypothesized in different plant species, as sterile lines contain lower PA levels compared to fertile lines [ 95 , 96 , 97 ]. Furthermore, quantitative and qualitative changes in the PA content occur during floral development [ 91 ].…”

The identification and characterization of transcripts involved in flower organ development, plant reproduction and metabolism represent key steps in plant phenotypic and physiological pathways, and may generate high-quality transcript variants useful for the development of functional markers. This study was aimed at obtaining an extensive characterization of the olive flower transcripts, by providing sound information on the candidate MADS-box genes related to the ABC model of flower development and on the putative genetic and molecular determinants of ovary abortion and pollen-pistil interaction. The overall sequence data, obtained by pyrosequencing of four cDNA libraries from flowers at different developmental stages of three olive varieties with distinct reproductive features (Leccino, Frantoio and Dolce Agogia), included approximately 465,000 ESTs, which gave rise to more than 14,600 contigs and approximately 92,000 singletons. As many as 56,700 unigenes were successfully annotated and provided gene ontology insights into the structural organization and putative molecular function of sequenced transcripts and deduced proteins in the context of their corresponding biological processes. Differentially expressed genes with potential regulatory roles in biosynthetic pathways and metabolic networks during flower development were identified. The gene expression studies allowed us to select the candidate genes that play well-known molecular functions in a number of biosynthetic pathways and specific biological processes that affect olive reproduction. A sound understanding of gene functions and regulatory networks that characterize the olive flower is provided.
