“…An in vitro propagation system provides plants with uniform genetic identity and can ensure clean planting materials (Shatnawi et al, 2011). It provides complementary conservation options for plant species with limited reproductive capacities including a number of rare and endangered species (Cenkci et al, 2007). Reports have been published on in vitro propagation of Curcuma zedoaria and C. longa using various explants such as rhizome sprout (Loc et al, 2005), bud or shoot-tip (Salvi et al, 2002;, leaf-base (Salvi et al, 2001), and immature inflorescence (Salvi et al, 2000).…”

IntroductionCurcuma aromatica Salisb. (Zingiberaceae), indigenous to South Asia, is a robust zingiber with stout underground rhizomes. This wild, aromatic, and attractive turmeric is probably the most useful among the turmeric members for its unique medicinal values. C. aromatica rhizome is a rich source of volatile oil, which consists of several major anti-tumor ingredients including demethoxycurcumin, β-elemene, curcumol, curdione, etc. (Zhou et al., 1997;Dulak, 2005). C. aromatica could promote blood circulation to remove blood stasis and treat cancers and angiogenesis (Kim et al., 2002). The oil infused via the hepatic artery has proven to exert ideal therapeutic effects in humans with primary liver cancer and rats with transplanted hepatoma (Cheng et al., 1999). Curcumin, the most prevalent active secondary ingredient in C. aromatica, acts as a promising agent in the treatment and/or prevention of Alzheimer's disease (Ringman et al., 2005). In addition, the rhizome is Abstract: A rapid and improved micropropagation protocol was developed for Curcuma aromatica, a threatened aromatic medicinal plant, using rhizome sprout as the explant. Stepwise optimization of different plant growth regulators, carbon sources, and basal media was adopted to establish an efficient micropropagation protocol. When cytokinins, such as benzyl amino purine (BAP) or 6-(α,αdimethylallylamino)-purine (2iP), were used either singly or in combination with naphthalene acetic acid (NAA) for shoot induction and multiplication, a single use of BAP was the most effective. As a carbon source, 3% (w/v) sucrose exhibits the greatest promotive effect on shoot initiation and proliferation compared with other carbon sources used. Among the basal media, full strength Murashige and Skoog (MS) media produced the best results, compared to other media studied. By using the most effective treatment from each category, an average of 13.2 shoots/per explant were produced after 6 weeks of culture. Moreover, 85% survival was achieved when rooted explants acclimatized ex vitro using a mixture of sterile sand, soil, and farmyard manure (1:1:1). In addition, antimicrobial activities of rhizome extracts were evaluated. Petroleum ether and chloroform extracts of field-grown rhizome showed potential antimicrobial properties against several human pathogenic bacteria including Bacillus subtilis, Staphylococcus aureus, Pseudomonas aeruginosa, Shigella sonnei, and Shigella dysenteriae, with a minimum inhibitory concentration (MIC) ranging from 0.03 to 0.5 mg/mL. Thus, the optimized micropropagation protocol may offer large-scale production of plantlets to meet industrial demand for the rhizome. Moreover, our results suggest the rhizome extract of C. aromatica is a promising antimicrobial agent.

Background and Objective: Macrotyloma uniflorum is nutritious and a good source of bioactive substances with high biological processes. The high frequency and efficient in vitro regeneration protocol have developed first time by utilizing embryo and ovary explants in Horsegram, Macrotyloma uniflorum. Materials and Methods: This research was carried out from horse gram paiyur-2 variety seeds derived embryo and ovary explants used by MS medium supplemented with cytokinins and auxins. Results: The phytohormone 0.4 mg LG 1 zeatin induced a maximum of 12 and 9 shoots from an embryo and ovary explants, respectively. The maximum frequency of rooting with about 9 roots was procured from the shoots cultured from embryonic explants using 0.2 mg LG 1 NAA and 7 roots were propagated from shoots derived from ovary explants. Overall studies observed that the embryonic explants show a high percent frequency of shoot and root induction when compared to ovary culture and further plantlets rose using embryonic explants with shoot growth period than the ovary explants. Conclusion: In vitro legume regeneration utilizing embryo and ovary is efficient, dependable and has fewer problems. Embryo explants were used to induce high-frequency plant regeneration, indicating that the ovaries are useful in genetic transformation.

“…Soil samples were collected from different habitats (Figures 2 and 3) of V. turcica, during its flowering season, between April and June 2015 by the associates of Nezahat Gökyiğit Botanical Garden, and evaluated. Cenkci et al (2007) reported that V. turcica has an extent of occurrence (EOO) of c. 40 km 2 as a result of intensive agricultural purposes such as the use of wetlands as agricultural land and groundwater abstraction for irrigation. Since V. turcica has a small EOO, this species has been categorized as Critically Endangered (CR) in the Red Data Books of Turkish plants (criterion B1ab (i, ii, iii)) (Ekim et al, 2000;Özhayat et al, 2005;IUCN, 2014;Kavak, 2014).…”

This study is an overview of the importance of soil nutrients for the maintenance of Vuralia turcica, which is an endemic in Turkey due to its natural habitats. Electrical conductivity, pH, and mineral element content (macroelements: nitrogen, phosphorus, potassium, calcium, magnesium, and sodium, and microelements: boron, cadmium, copper, iron, manganese, nickel, lead, and zinc) were analyzed in 21 soil samples taken at 30-60 m depth at 21 points from 8 different locations where V. turcica was growing to determine nutrient content, which is important for soil fertility and controls the crop yield. According to pH analysis, all samples were strongly alkaline (pH 8.62 to 9.30). Only one sample taken from the Kırca region was saline/alkaline and other samples were saltless. All samples were not toxic in reference to Cd level and were rich in terms of Na, K, Mg, and Ca, whereas Ni and P content were lower than the recommended amount in all samples tested. B, Cd, Cu, and Fe contents were sufficient according to ideal soil nutrient content level in all samples. N level was sufficient in all except for 3 soil samples. All tested soil samples were considered poor in Zn content, which varied from 0.19 to 1.83.
