“…These polyphenols might therefore be biochemical inhibitors of the induction of embryogenic structures in cotton callus cultures. This would be in line with other authors who showed that the reduced endogenous pool of cinnamic acids stimulated the formation of somatic embryos (Cvikrova et al, 2003). The phenolic compounds synthesized by both cultivar calli were phenolic acids, except catechin (2) and rutin (6), which belong to the tannin and flavonoid groups respectively.…”

Abstract.-We study the production of polyphenols by callus cultures from two cultivars of cotton (Gossypium hirsutum L.). Coker 312 produces the best calli and has embryogenic potential contrary to that of R405-2000, which is nonembryogenic. There is a relationship between the level of phenolic compounds and the callus cultures. Callogenesis in Coker 312 is highly correlated to a higher content of catechin, caffeic acid, ferulic acid, rutin, o-coumaric acid and salicylic acid. On the other hand, the cinnamic acid derivates (trans-cinnamic, cis and trans-methoxycinnamic acids) found in high amounts in R405-2000 calli could have a negative influence on the induction of cotton callogenesis. Key wordsRésumé.-Nous avons étudié la production en polyphénols de cultures en cal de deux variétés de cotonnier (Gossypium hirsutum L.). La variété Coker 312 produit les meilleurs cals et possède des potentialités embryogènes, contrairement à la variété R405-200 qui est non embryogène. Nous avons mis en évi-dence une relation entre les teneurs en composés polyphénoliques et les cals cultivés. La callogénèse chez Coker 312 est fortement corrélée avec une plus forte teneur en catéchine, acide caféique, acide ferulique, rutine, acide orthocoumarique et acide salicylique. Par contre, les dérivés de l'acide cinnamique (acides trans-cinnamique, cis and trans-methoxycinnamique), présents en grande quantité dans les cals de R405-2000, pourraient avoir une influence négative sur l'induction de la callogénèse chez le cotonnier.

“…Genes encoding enzymes in the phenylpropanoid pathway are up-regulated during barley (Hordeum vulgare) microspore embryogenesis upon stress treatment of the anthers (Jacquard et al, 2009), and alterations in this pathway have been correlated with the developmental potential of sessile oak (Quercus spp.) somatic embryos (Cvikrova et al, 1998(Cvikrova et al, , 2003. "Flavonoid biosynthesis" was one of the pathways overrepresented in superembryogenic Medicago truncatula (line 2HA) explants compared with its comparatively nonembryogenic progenitor Jemalong.…”

“…Conjugated amines accumulate dramatically in response to certain developmental or stress factors. 8,39 Polyamine conjugation seems to be advantageous for the long-term regulation of free PA levels. This mechanism allows to reduce the risk of accumulation of harmful metabolites, produced by oxidative deamination.…”

“…This mechanism allows to reduce the risk of accumulation of harmful metabolites, produced by oxidative deamination. 39 Jasmonates have been shown to induce over-accumulation of methylputrescine and conjugated PAs in Hyoscyamus muticus L. root cultures. 40 Jasmonic acid and its precursor 12-oxophytodienoic acid increased in hop nodules after 45 days of culture.…”
