“…Compared with traditional methods, in vitro techniques have many advantages, such as independence of seasonal variation for massal propagation, identifi cation and production of clones with the desired characteristics, and the ability to manipulate the microenvironment to increase production of the metabolite of interest (EL-TARRAS et al, 2012). The use of elicitors in in vitro culture has been one of the most effective strategies to increase the formation of secondary metabolites, including the application of certain hormones associated with stress in plants (JALLEL et al, 2009;PEROTTI et al, 2010).…”

“…Inside the cell, copper is required at several locations, such as the cytosol, endoplasmic reticulum, mitochondria, chloroplasts, and apoplasts (Yruela, 2009). Copper also plays a variety of roles in plant metabolic processes including photosynthesis, respiration, antioxidant activity, the biosynthesis of cell wall components, lignification, ethylene detection, and the production of secondary metabolites (Pilon et al, 2006;Burkhead et al, 2009;Lequeux et al, 2010;Perotti et al, 2010).…”

This study evaluates the chlorophyll index and fluorescence parameters of chlorophyll a in Alternanthera tenella grown in different concentrations of copper (Cu). The A. tenella plants were hydroponically grown in a complete nutrient solution for 3 days and were then transferred to the same solution containing different copper concentrations [0.041, 0.082 (control), 0.164, 0.246, and 0.328 mM]. The plants were maintained in these solutions for 13 days. The nutrient solutions were replaced every 3 days, and the plants were evaluated at 6 days and 13 days after the start of the treatment. An increase in the chlorophyll index was observed at copper concentrations of 0.164, 0.246, and 0.328 mM on days 6 and 13. These concentrations of copper also affected the fluorescence parameters and caused a reduction in the pool of the final photosystem I (PSI) electron acceptors, a decrease in the total number of electron carriers per reaction centre, a decrease in the parameters related to the flow, yield, and efficiency for the reduction of the final PSI acceptor, and a decline of the total photosynthetic performance index. Therefore, high doses of copper affect the functionality of the PSI, decreasing the reduction flow of the final PSI electron acceptors.

“…This value was much higher compared with previous studies that used elicitors to increase this pigment in species of the Alternanthera genus, in which the maximum concentrations obtained were approximately 40 mg of amaranthine in 100 g of fresh mass (Perotti et al, 2010;Reis et al, 2015).…”

ABSTRACT. Among the compounds produced by plants, pigments such as betalains have received attention from both food and pharmaceuticals industries. The Alternanthera sessilis species produces these pigments, though in small quantities, and so it is necessary to increase production. Thus, many studies use elicitors that are capable of triggering physiological or morphological responses in plants. The objective was to establish callus production in A. sessilis grown under different combinations of growth regulators and light qualities and to assess whether these factors can increase betalain and flavonoid production. Leaf and internodal explants in MS medium with different growth regulators were used to obtain calli, which were subsequently transferred to a betacyanin induction medium remaining for 40 days under different light qualities (white, blue, red, and dark). The most suitable treatment for callus formation and subsequent betalain and flavonoid induction was to combine a medium containing 6.7 μmol L Produção de pigmentos em calos de Alternanthera sessilis mediados por reguladores de crescimento e luz RESUMO. Dentre os compostos produzidos pelas plantas, os pigmentos, como as betalaínas, vêm recebendo destaque tanto pela indústria alimentícia como farmacêutica. A espécie Alternanthera sessilis produz esses pigmentos, porém em pequenas quantidades, sendo necessário incrementar a produção. Para isso, muitos estudos utilizam elicitores que são capazes de desencadear respostas fisiológicas ou morfológicas nas plantas. O objetivo do trabalho foi estabelecer a produção de calos de A. sessilis crescidos quando submetidos a diferentes combinações de reguladores de crescimento e qualidades de luz, e avaliar se esses fatores são capazes de incrementar a produção de betalaínas e flavonoides. Foram utilizados explantes foliares e internodais em meio MS com diferentes reguladores de crescimento para obtenção dos calos que, posteriormente, foram transferidos para meio de indução de betacianina, onde permaneceram por 30 dias sob diferentes qualidades de luz (branca, azul, vermelha e escuro). O tratamento mais propício para formação de calos e consequente indução de betalaínas e flavonoides foi a combinação do meio contendo 6,7 μmol L -1 2,4-D e 9,0 μmol L -1 BAP e a luz azul. Conclui-se que a elicitação física pela luz em conjunto com a concentração adequada de reguladores de crescimento em calos é capaz de incrementar a produção de metabólitos de interesse comercial.Palavras-chave: betalaína, flavonoides, metabólitos secundários, plantas medicinais.
