“…The result obtained with AgNO 3 could be attributed to nonexcessive ethylene production in the culture vessels (Chandra et al, 1997) of lentisk. Our results also showed that the addition of PG was not essential for shoot proliferation or multiple shoot formation (Teixeira da Silva et al, 2013) in lentisk. The effects of the highest shoot-promoting concentrations of GA 3 (0.1, or 0.3 mg/L) or NAA (1.0 mg/L) individually combined with AgNO 3 (4.0 mg/L) and 1.0 mg/L BA on shoot multiplication were also assessed.…”

IntroductionPistacia lentiscus L., which is also known as the lentisk or mastic tree, is widespread from Asia Minor to the Canary Islands and throughout the Mediterranean region (Ak and Parlakcı, 2009). It is an evergreen shrub with lovely red berries and dark green foliage and is often used as an ornamental plant (Mascarello et al., 2007). Lentisk can adapt to several climatic and pedological conditions (Zohary, 1952), such as severe drought (Correia and Catarino, 1994) and calcareous soil; it also exhibits regrowth after forest fires or deforestation (Ladd et al., 2005).P. lentiscus is also the source of a unique resin called mastic gum or mastic. It is obtained by wounding the trunk and thick branches of the male trees, since the females produce low levels of mastic (Acar, 1988). The cultivated male trees and mastic production have been exclusively maintained on the Greek island of Chios for a long time. Mastic production is also carried out in the adjacent Çeşme Peninsula of İzmir, Turkey, where ecological conditions are similar to Chios, Greece; however, mastic production in Çeşme is very restricted and does not match the quantity of the production on Chios Island (Baytop, 1968;Isfendiyaroglu, 2000). The agricultural activities and tourist facilities established in Çeşme have resulted in the continuous loss of mastic trees (Dogan et al., 2003). Therefore, the Turkish Foundation for Combating Soil Erosion for Reforestation and the Protection of Natural Habitats has been leading a project to protect the native mastic trees and establish new plantations on the Çeşme Peninsula to revive viable commercial production (www. tema.org.tr). In addition, a forest fire recently occurred on Chios Island and destroyed a total of 12,740 ha, which resulted in massive damage not only to the island's agricultural economy, but also to the world supply of Chios mastic (http://effis.jrc.ec.europa.eu). Mastic gum has a long tradition in folk medicine and has been used by healers for several treatments, such as for hypertension, coughs, sore throats, eczema, stomachaches, kidney stones, and jaundice (Ljubuncic et al., 2005b;Gardeli et al., 2008).The essential oil of mastic contains several secondary metabolites such as myrcene, limonene, terpinen-4-ol, alpha-pinene, beta-pinene, alpha-phellandrene, sabinene, para-cymene, and gamma-terpinene (Castola et al., 2000).

“…Cellular auxin levels depend on the rate of anabolism, catabolism, transport and conjugation at any given time in a tissue (Ljung 2013). Depending on the type and concentrations, phenolic compounds are known to inhibit or promote rooting mediated by their influence on the metabolism and concentration of active forms of auxins in plants (Peer and Murphy 2007;Wu et al 2007;De Klerk et al 2011;Teixeira da Silva et al 2013). Particularly, phenolic inhibitors of IAA oxidase such as PG, chlorogenic acid and rutin have been shown to enhance auxin activities (Gaspar et al 1996).…”

“…1). While PG has been documented to possess numerous applications in micropropagation (Teixeira da Silva et al 2013), eckol is mostly valued for its therapeutic potential (Rengasamy et al 2014). However, recent evidence of potential growth stimulatory activity of these compounds (Rengasamy et al 2015) has aroused our interest to fully elucidate the physiological effects of these phenolics in agricultural productivity, especially in the cultivation of plant species with medicinal and ornamental values.…”

Eckol, a major phenolic compound isolated from brown seaweed significantly enhanced the bulb size and bioactive compounds in greenhouse-grown Eucomis autumnalis. We investigated the effect of eckol and phloroglucinol (PG) (phenolic compounds) isolated from the brown seaweed, Ecklonia maxima (Osbeck) Papenfuss on the growth, phytochemical and auxin content in Eucomis autumnalis (Mill.) Chitt. The model plant is a popular medicinal species with increasing conservation concern. Eckol and PG were tested at 10(-5), 10(-6) and 10(-7) M using soil drench applications. After 4 months, growth parameters, phytochemical and auxin content were recorded. When compared to the control, eckol (10(-6) M) significantly improved bulb size, fresh weight and root production while the application of PG (10(-6) M) significantly increased the bulb numbers. However, both compounds had no significant stimulatory effect on aerial organs. Bioactive phytochemicals such as p-hydroxybenzoic and ferulic acids were significantly increased in eckol (10(-5) M) and PG (10(-6) M) treatments, compared to the control. Aerial (1,357 pmol/g DW) and underground (1,474 pmol/g DW) parts of eckol-treated (10(-5) M) plants yielded the highest concentration of indole-3-acetic acid. Overall, eckol and PG elicited a significant influence on the growth and physiological response in E. autumnalis. Considering the medicinal importance of E. autumnalis and the increasing strains on its wild populations, these compounds are potential tools to enhance their cultivation and growth.

“…More recently, many authors have reported of the successful use of other synthetic auxins such as picloram (4-amino-3,5,6-tricloropiconic acid) and dicamba (3,6-dichloroanisic acid) (Mongomake et al 2015). The application of new generation of growth regulators such as oligosaccharides, jasmonate, polyamines, brassinosteroids (George et al 2008) and phloroglucinol (Teixeira da Silva et al 2013) has also proved to be useful for primary somatic embryos induction in many plant species. Therefore to improve the embryogenic system for mutation induction, the use of synthetic auxins such as picloram or dicamba as well as jasmonates and brassinosteroids is worth investigating particularly in cassava landraces whose embryogenic competence is not known.…”

Somatic embryogenesis, an efficient regeneration system that is being used successfully in genetic transformation, can be coupled with mutation induction to breed for cassava varieties with desired traits. The embryogenesis system requires the initiation of totipotent cells which can be used as targets for mutagenic treatments. However, initiation of these totipotent cells is low, highly genotypic dependent and has low plant conversion rate. Thus, for its successful application in mutation induction, the system needs to be optimised to overcome these drawbacks. To optimise the system, totipotent cells are initiated on embryo initiation medium (EIM) which consisted of Murashige and Skoog (Physiol Plant 15:473-497, 1962) basal salts supplemented with picloram and 2,4-dichlorophenoxy acetic acid (2,4-D) to produce callus. After 21 days, calli produced are cultured for embryo maturation on maturation medium (EMM) or can also be treated with mutagenic agents for mutant induction. The resulting primary embryos are recycled three consecutive times, each by fragmentation of the cotyledons followed by culture on embryo initiation medium to produce more matured embryos. Somatic embryos produced are then successfully converted into plants by abscisic acid pretreatment in embryo maturation medium or by air desiccation under the laminar flow hood. The methodology described offers optimised, reproducible procedures of somatic embryogenesis for its incorporation into mutation breeding programmes in cassava.
