“…Studying Kolonchoe pinnata, Nascimento et al (2013) observed accentuated increase in flavonoids when exposed to blue light. This increase was also observed by Xu et al (2014), total anthocyanin content of strawberry fruits significantly increased after four days of treatment with blue light (40 μmol m -2 s -1 ) at 5° C compared to the control fruits.…”

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.

“…The positive effects of light-emitting diode (LED) irradiation on anthocyanin accumulation have been reported in strawberries (Fragaria 9 ananassa Duch.) (Xu et al 2014), leaf baby lettuce (Lactuca sativa L.) (Samuolien_ e et al 2012) and grapes (Kondo et al 2014). These findings suggest that interactions exist among light, ABA, sugar and anthocyanin.…”

The effects of red-and blue-light irradiation at night on abscisic acid (ABA) synthesis and anthocyanin and sugar concentrations were examined in grape vines, which were grown in two different seasons. In grapes cultivated with early heating, the ABA concentrations were highest in blue-light-emitting diode (LED)-treated skin; however, those in grapes cultivated in the ordinary growing season were highest in red-LED-treated skin. The expressions of 9-cis-epoxycarotenoid dioxygenase (VvNCED1) and ABA 8 0 -hydroxylase (VvCYP707A1) were high in each treatment at veraison regardless of the growing season. In both seasons, anthocyanin concentrations were highest under the blue-LED treatment, followed by the red-LED treatment. The expressions of VlMYBA1-2, VlMYBA2, and VvUFGT coincided with anthocyanin concentrations. Sugar concentrations were increased by the blue-or red-LED treatment dependent on the growing season. The results suggest that blue-or red-LED irradiation at night may influence the ABA and anthocyanin metabolism including VvNCED1, VlMYBA1-2, and VlMYBA2 and sugar synthesis in grape berries, although the degree of the effects differs with the growing season.

“…Postharvest effects on lignification have been described for bamboo shoots (Luo, Xu, & Yan, ), strawberry (Xu et al, ), muskmelon (Liu et al, ; Wang et al, ; Yuan et al, ), red raspberry (Flores & Castillo, ), walnut (Araji et al, ), asparagus (An, Zhang, & Lu, ), and zucchini fruit (Carvajal, Palma, Jamilena, & Garrido, ). The treatments used to influence lignification included the following: packaging in a modified atmosphere (Shen, Kong, & Wang, ), harpin (Tang et al, ; Wang et al, ), methyl jasmonate treatment (Flores & Castillo, ), blue‐light irradiation (Xu et al, ), acibenzolar‐S‐methyl treatment (Liu et al, ), chlorine dioxide treatment (Yang et al, ), and a hot water dip (Luo et al, ; Yuan et al, ). Most of the studies focusing on lignification or related enzyme activity have proved some effect on preservation during storage.…”

Lignification and changes in the enzymes involved in lignin biosynthesis were investigated in relation to the reduced tenderness occurring during the postharvest storage of fresh waxy corn at 20 °C. The firmness of the corn and its lignin and polyphenol contents increased as storage time increased. The lignin content was significantly correlated (p < .05) with the polyphenol content and firmness. Phenylalanine ammonia‐lyase was not the rate‐limiting enzyme in polyphenol biosynthesis, whereas the cinnamate 4‐hydroxylase activity was significantly correlated (p < .05) with the polyphenol content. The activity of coenzyme A ligase (4CL) had a limited effect on the polyphenol content. Peroxidase was significantly correlated (p < .05) with the lignin content, while no significant (p > .05) effect of polyphenol oxidase or cinnamyl alcohol dehydrogenase (CAD) on the lignin content was observed. Practical applications Tenderness is a main factor in sensory quality of fresh waxy corn. Secondary cell wall lignifications induced by phenylpropanoid pathway is the main reason of tenderness decline for postharvest fresh waxy corn. But little information of lignin accumulation of fresh waxy corn is obtained from the present studies. Analyzing the changes of lignin and related precursor materials, enzyme activities will help to comprehensively understand the regulatory mechanism of postharvest lignification of fresh waxy corn, which can provide suitable methods to delay postharvest lignin accumulation, and maintain the eating quality of fresh waxy corn.
