“…While AT3 is a candidate to encode for capsaicinoid synthase, peppers with loss-of-pungency mu- tations in AT3 have been reported to synthesize capsaicinoids when the immediate precursors, vanillylamine and branched-chain fatty acids, are supplied exogenously (Iwai et al, 1977). Another candidate had been reported, Csy1, but that report has since been retracted (Prasad et al, 2006(Prasad et al, , 2007. The final condensation enzyme is still an open question.…”

(M.M.J.) Capsaicinoids are the pungent alkaloids that give hot peppers (Capsicum spp.) their spiciness. While capsaicinoids are relatively simple molecules, much is unknown about their biosynthesis, which spans diverse metabolisms of essential amino acids, phenylpropanoids, benzenoids, and fatty acids. Pepper is not a model organism, but it has access to the resources developed in model plants through comparative approaches. To aid research in this system, we have implemented a comprehensive model of capsaicinoid biosynthesis and made it publicly available within the SolCyc database at the SOL Genomics Network (http://www.sgn.cornell.edu). As a preliminary test of this model, and to build its value as a resource, targeted transcripts were cloned as candidates for nearly all of the structural genes for capsaicinoid biosynthesis. In support of the role of these transcripts in capsaicinoid biosynthesis beyond correct spatial and temporal expression, their predicted subcellular localizations were compared against the biosynthetic model and experimentally determined compartmentalization in Arabidopsis (Arabidopsis thaliana). To enable their use in a positional candidate gene approach in the Solanaceae, these genes were genetically mapped in pepper. These data were integrated into the SOL Genomics Network, a clade-oriented database that incorporates community annotation of genes, enzymes, phenotypes, mutants, and genomic loci. Here, we describe the creation and integration of these resources as a holistic and dynamic model of the characteristic specialized metabolism of pepper.

“…It is also very popular among the people for its medicinal value because the extract of chili is used in different pharmaceutical products. The pungency in chilli is due to the presence of a volatile alkaloid 'Oleoresin capsaicin', a major alkaloid among capsaicinoids produced only in Capsicum fruits [2]. Chilies are highly nutritive and contain a high proportion of digestible proteins, carbohydrates, minerals and vitamins.…”

“…Recently Gururaj et al (2004) attempted in vitro clonal propagation in C. frutescens, wherein a maximum of 1-3 shoots were reported. A highly reproducible regeneration system with greater frequency of multiple shoot production is required to improve this important crop through genetic engineering especially in order to mobilize the desired pungency gene (Prasad et al 2006) for its over expression or suppression for better economic perspective. Silver ions are reported to inhibit ethylene action (Beyer, 1976) whereas cobalt ions inhibit ethylene biosynthesis (Roustan et al 1989).…”

The influence of silver nitrate (AgNO 3 ) and cobalt chloride (CoCl 2 ) on shoot multiplication and in vitro flowering in Capsicum frutescens Mill. was investigated. Exogenous administration of AgNO 3 and CoCl 2 at a concentration of 30 µM resulted in the maximum tissue response in terms of shoot length and number of shoots after 45 days culturing on MS medium. Both silver nitrate (40 µM) and cobalt chloride (30 µM) influenced in vitro flowering after 25 and 45 days respectively. This is the first report on in vitro flowering in C. frutescens. The study also demonstrated successful transformation of pollen obtained from the in vitro flowers. Since capsicum is highly recalcitrant to in vitro plant regeneration, the results of the study may be highly useful in transformation of capsicum using germ free in vitro flowers.
