Phenolic compounds and somatic embryogenesis in cotton (Gossypium hirsutum L.)

Abstract

Studies of phenolic compounds were performed during cell suspension cultures in relation with the induction of embryogenic structures in two cultivars of cotton. Coker 312 produced embryogenic structures, unlike R405-2000 which was found to be a non-embryogenic cultivar. Embryogenesis induction in Coker 312 was strongly linked to a higher content of caffeic, ferulic and salicylic acids and to the appearance of p-coumaric acid, benzoic acid, transresveratrol, catechin and naringenin.

Effects of different light quality on growth, photosynthetic characteristic and chloroplast ultrastructure of upland cotton (Gossypium hirsutum L.) seedlings

“…Plant leaves were the main organ of photosynthesis, and structure and function of chloroplasts are important for the growth of plants and influence physiological and ecological responses (Peng and Zhou, 2009). Upland cotton was the primary species of cotton cultivated for fibers to be used in textile industry (Kouakou et al, 2007). Seedling culture and transplantation was major system for Chinese cotton production.…”

Pre-procambial cells are niches for pluripotent and totipotent stem-like cells for organogenesis and somatic embryogenesis in the peach palm: a histological study

“…Histochemical monitoring was used to determine the essential factors involved in the acquisition of embryogenic competence in cells and/or tissues (Kouakou et al 2007;Pinto et al 2011;Rocha et al 2011) and the distinction of embryogenic competence from organogenetic events. The establishment of in vitro plant regeneration, through direct organogenesis or somatic embryogenesis in the peach palm, has been described (Almeida and Kerbauy 1996;Almeida and Almeida 2006;Graner 2009).…”

Polyphenol levels in two cotton (Gossypium hirsutumL.) callus cultures

“…Thus, qualitative and even quantitative changes in phenolic composition occur during callogenesis and considerable differences can be observed between embryogenic and non-embryogenic cultivars. We also showed in cell suspensions that differences exist between two cultivars: Coker 312 and R405-2000 (Kouakou et al, 2006(Kouakou et al, , 2007. To our knowledge, however, there has been no report on the nature and/or concentrations of phenolic compounds in calli of cotton cultivars.…”

“…The chromatographic conditions used in this study were those we described previously (Kouakou et al, 2006(Kouakou et al, , 2007. HPLC analysis was performed on a Varian apparatus equipped with an autosampler model 410, a Prostar pump model 210, a Prostar diode array detector model 335, and using Star software.…”
