The Effect Of Some Plant Growth Regulators And Their Combination With Methyl Jasmonate On Anthocyanin Formation In Roots Of Kalanchoe Blossfeldiana

Abstract

In this study, we investigated the effect of plant growth regulators (PGRs) -auxins, gibberellin, cytokinin, abscisic acid, brassinosteroid, ethylene and their interaction with methyl jasmonate (JA-Me) applied to roots of the whole plants Kalanchoe blossfeldiana on the accumulation of anthocyanins in roots. The highest stimulation of anthocyanins synthesis was stated with application of JA-Me alone. In response to treatments with the other tested PGRs, the content of anthocyanins in roots of a whole plant was different depending on the concentration of the PGR when being applied alone or together with JA-Me. Auxin, indole-3-acetic acid (IAA) at a concentration of 50 mg·L -1 , indole-3-butyric acid (IBA) at 5 mg·L -1 and abscisic acid (ABA) at 10 mg·L -1 induced anthocyanin accumulation with approximately 60-115% compared to the control while 24-epibrassinolid (epiBL), gibberellic acid (GA3) and 6-benzylaminopurine (BAP) had no effect on the anthocyanin accumulation. The simultaneous administration of the PGRs with JA-Me usually resulted in the accumulation of anthocyanins in roots in a manner similar to that caused by JA-Me. PGRs applied to isolated roots did not stimulate anthocyanin accumulation, except for the combination of JA-Me with 50 mg·L -1 IAA. The results indicate that in K. blossfeldiana, the aboveground parts of the plant play an important role in the biosynthesis of anthocyanins in roots.

Improvement Yield and Quality of Dahlia Flowers by Exogenous Application of Gibberellic Acid and Salicylic Acid under Sandy soil Conditions

“…Positive impact on the biosynthesis of anthocyanin has been established for plant hormones, such as gibberellins (Goraj et al, 2014). Gibberellins (GA 3 ) have been found to enhance a number of desirable factors including anthocyanin contents; Ohlsson and Berglund (2001) reported that application of GA 3 increased anthocyanin content in Catharanthus roseus.…”

“…At the same time increased the quantum ef ciency of energy trapping in PSII and ef ciency index was accompanied by decrease in energy dissipation suggesting more effective energy usage. Methyl jasmonate (JA-Me) is an elicitor that causes the formation of anthocyanins in roots of Kalanchoe blossfeldiana (Góraj et al, 2014;Góraj-Koniarska et al, 2015). The anthocyanins are accumulated in roots of intact plants, but not in excised roots.…”

Coordinated Regulation of Anthocyanin Biosynthesis Genes Confers Varied Phenotypic and Spatial-Temporal Anthocyanin Accumulation in Radish (Raphanus sativus L.)

“…The color of the taproots varies from white to red, to purple-pink, to green, to bicolor, due to its accumulation of large amounts of anthocyanins (Chen et al, 2016). Studies on anthocyanin and the underlying molecular mechanism in radish dwell on single-tissue analysis and mostly at maturity stage (Park et al, 2011; Bae et al, 2012; Chen et al, 2016). A growing body of research provides evidence that as growth advances, anthocyanin accumulation is not localized in the plant but rather, discriminatively accumulates in specific clusters of cells located in different plant tissues (Zuluaga et al, 2008; Zhang et al, 2014).…”
