We are experimenting with display styles that make it easier to read articles in PMC. Diaz MS, Palacio L, Figueroa AC, Goleniwski ME. Also, mucilages have been reported in the epidermis of senna (Cassia acutifolia Delile), Alexandrian senna (Cassia augustifolia Vahl), Cassia auriculata Linn. A potential plasmid-curing agent, 8-epidiosbulbin E acetate, from. The use of micropropagation techniques for endangered plant genetic resources conservation was recognized late in the 70s[6]. A: Multiple shoots obtained from green house; B: Multiple shoots obtained from underground bulbil. Leaves 9-25 x 8-23 cm, ovate-suborbicular, base deeply cordate, apex acuminate to shortly caudate, membranous, glabrous, basally 9-11-ribbed; petiole to 20 cm long. Biochemical investigations of D. floribunda following gamma irradiations were studied by Gupta et al. Cuticular striated wall has been reported in the epidermal imprint of the lower surface of the leaf of D. bulbifera using non-toxic mucilage[42]. After 3-6 weeks of culturing, cultures were subcultured in fresh basal medium depending on the experiments. A. Osiyemi at the Forest Herbarium Ibadan where the voucher specimen with number “FHI 109529” was deposited. Phytochemistry 28(3):947-949. However, the clinical application has been limited for its hepatotoxicity. Selain itu terdapat pula Dioscorea bulbifera, Dioscorea pentaphylla, dan Dioscorea nummularia. Through the acute toxicity of various extracts including the EtOAc fraction (EF) and the non-EtOAc fraction (Non-EF) from ethanol, and the ethanol itself, we found that the EF contains the toxic ingredients of D. bulbifera rhizome.

He analyzed the Japanese Dioscorea species, three of which did not contain sapogenins. (1981) in rhizomes of the Chinese D. zingiberensis. This is a good paper elucidating the importance of micro characters in the confirmation of the identity of both micro propagated and wild samples of D. bulbifera. Morphology and the ability to form microtuber were also found to be unaltered in cryopreserved embryo-derived plantlets. Mucilages are evenly and widely spread within the epidermal cell of the wild plant than the micropropagated plant. The presence of anisocytic stomata in D. bulbifera together with anomocytic stomata may serve as distinguishing character for its identification from other Dioscorea species. Dioscorea bulbifera is a potent medicinal plant used in both Indian and Chinese traditional medicine owing to its rich phytochemical diversity. The plant was identified by Mr. O. The near endangered status of D. bulbifera makes it imperative to find appropriate means of its conservation. It is important to note that using tissue culture technique the problem of freeing the yams from virus diseases can also be solved. Singh IP, Parthasarathy VA, Handique PJ. However, it is not a legal authority for statutory or regulatory purposes. 1753. Callus, shoot, leaf and root formation from nodal segments of D. bulbifera (parameters of growth scored after 6 weeks). Wadekar J, Sawant R, Honde B.

There is a dearth of published research on its invasive biological attributes including vine growth and biomass production by plants generated from bulbils. The yield of diosgenin in various species of Dioscorea is presented in Table Diosgenin content in selected Dioscorea species. Mr. O. Comparison of diagnostic features of wild and in vitro foliar epidermis of abaxial and adaxial were carried out using independent student t-test. The aerial bulbil serves as the main storage organ rather than underground tubers or bulbils[3]. 2016. ... Observations on the floral morphology of some Dioscorea species (Dioscoreaceae) in Nigeria. The consumption of steroid drugs increases every year. Bulbils occur in the leaf axis of numerous species of Dioscorea and contribute greatly to vegetative propagation. Dioscorea bulbifera L., Sp. Dioscorea bulbifera (air potato): This true yam also produces axillary tubers but these can sometimes weigh several pounds. (1977) found that D. bulbifera has diuretic and anti-inflammatory activity. Healthy vines with active buds were collected from 12 weeks old plants of D. bulbifera raised and maintained in the green house. The stems range from thin (1-milli- Foliar anatomy and histochemistry in seven species of, Bejoy M, Dan M, Anish NP, Anjana RG, Nair BJ, Radhika K, et al. Abstract This biology is the 2nd in a series of Agriculture Handbooks dealing with the major species of yams. A taxonomic study of some species in. Medicinal and Aromatic Plants. Slight variations included closed stomata pore in the wild and open in the in vitro cultivated plants, cuticularization of epidermal walls was observed in the adaxial and abaxial surfaces of the wild whereas it was noticed only on the abaxial surfaces of the in vitro plant. These specific conditions are responsible for the structural changes occurring in micropropagated plants. Naphthalene acetic acid had been reported to inhibit root elongation in a wide range of concentrations from 0.01 µmol/L to 1 µmol/L[32]. Generally, mean length of stomata size, epidermal cell size and trichomes of the abaxial and adaxial surfaces in wild plant were larger than micropropagated D. bulbifera while the average epidermal trichome in abaxial surface was larger compared with the wild. Dioscorea bulbifera is also called Air potato it belongs to yam species. It is therefore imperative to consider conserving this medicinally useful plant genetic resource. Previous workers have reported that phytochemicals including saponins, polyphenols and mucilage are the likely active components of Dioscorea species[35]–[37]. Coursey (1967) mentioned 53 Dioscorea species containing sapogenin, and a high percentage of diosgenin content (more than 2%) was found in 23 species ineluding D. composita, D. deltoidea and D. floribunda. Many results suggest that the high diosgenin content can be obtained by biotransformation, and this method should be developed in the future. Selections from the book: “Medicinal and Aromatic Plants II”, 1989. Essiett UA, Bala DN, Agbakahi JA. Joly et al. It is named by the monk Charles Plumier after the ancient Greek physician and botanist Dioscorides This has led to the near extinction status of this plant in the southeastern part of Nigeria[5]. Earlier workers reported shoot regeneration of 42%-75% in Dioscorea rotundata when cultured in MS medium supplemented with NAA (0.1 µmol/L)+BAP (0.20 µmol/L) and shoot plantlet regeneration of 60%-82% obtained in media made of NAA (0.05 µmol/L)+BAP (0.20 µmol/L) or BAP (0.46 µmol/L)+kinetin (0.50 µmol/L) in Dioscorea alata[29].

Pharmacognostic studies of the leaves and stem of, Yasmiri G, Khan MA, Shaheen N, Hayat MQ. At the moment, in vitro technique has found increasing significance as a complementary means to in situ plant conservation, especially for vegetatively propagated and recalcitrant seed-producing species[7]. New sources for important sapogenins have been indicated. Thin cuticle seems to be a common feature for all in vitro cultivated plant species. They concluded, based on this limited sample, that pollen morphological characters provided useful systematic data within the genus. Leaf anatomy of orchids micrpropagated with different silicon concentrations. NAA, an auxin, can effectively induce shoot emergence when combined with an adenine derivative (BAP). Nodal segments of D. bulbifera with elongated shoots. Other authors found traces of diosgenin in D. bulbifera. Abstract. Comparative qualitative and quantitative features of foliar epidermis of wild and micropropagated D. bulbifera. In all media treatments, 10%-30% callus was generated (Figure 6A). In view of the biological and medicinal importance of D. bulbifera, and the report of its near extinction in southeast region of Nigeria, the present study was designed to compare qualitative and quantitative micro-morphological characteristics of the wild and micropropagated plants which may be employed for correcting crude drug identification. Dioscorea bulbifera is also called Air potato it belongs to yam species. Morphologically, the leaf description of the wild and micropropagated plants were similar in terms of leaf venation which was parallel and vein convergence at the base, leaf shape in both was cordate with long petiole and alternate arrangement, leaf margin was entire with aerial bulbils produced from the node in both wild and micropropagated plants. The techniques utilized in this study were in accordance with methodology previously reported in literature[25]–[27]. In recent years great advances in research on the Dioscorea species have been observed. They were rinsed in distilled water until explants were clean and free from Tween 20. The main determinant factors are high relative air humidity, air composition and culture media content. Asian Pacific Journal of Tropical Biomedicine. Estudio etnobotánico de la papa de aire Other authors have described the biological properties of diosgenin. Later, Marker et al. Therefore, in the case of shifting from in vitro to ex vitro cultures, the cutine is gradually synthesized, with the decrease relative humidity of the medium in which the plant lives. This paper adds new data on the pollen and orbicule morphology of 61 Dioscorea L. (Dioscoreaceae) species to the survey of Schols et al. It comprises ca. Dioscorea bulbifera L. (Chinese: Huangdu, common name: air potato) is a traditional herbal medicine in China, and it is also one of the most widely consumed yam species, especially in West Africa. Bulbifera. Foliar microscopic features of adaxial epidermis of D. bulbifera. Morphology and the ability to form microtuber were also found to be unaltered in cryopreserved embryo-derived plantlets.

Dioscorea bulbifera is a vigorously twining, long-stemmed perennial vine with non-spiny stems to 20 m or more in length, freely branching above; internodes round or slightly angled in cross section and they twine counter-clockwise. Morphological characteristics are used to distinguish between different soils and they are used in classification of soils (Soil Survey Staff, 1998). Another kind of chemical investigation of Dioscorea species is the biotrans-formation of steroidal saponins. Characterization and maintenance of yam (Dioscorea spp.) A: Formation of single bulbil with aerial root; B: Single bulbil at the nodal base. preussii Pax,D. Among the many documented medicinal folk uses, the plant is used to paste produced from the tubers to treat swelling and as a cure for snakebite and scorpion stings in Africa and Asia, and the bulbils are used to cure thyroid diseases and cancer in traditional Chinese medicine[18]–[20]. The tubers are edible and have often been used in Traditional Chinese Medicine (TCM) and Ayurvedic medicine to treat … et al.

Jimenez-Montero M, Aguilar-Martínez A. Food tuber yams include D. alata, D. bulbifera, D. rotundata, D. cayenensis, D. esculenta and D. trifida. Anomocytic stomata type reported in this work agrees with a previous report of anomocytic stomata in the order Dioscorales as in the case of Dioscorea hispida[40]. Phytochemistry 20:1569-1571. available on Dioscorea bulbifera and its management in Florida. Morphology. morphology of the rhizomes and tubers of five different species of Dioscorea, namely D. balcanica, D. bulbifera, D. polystachya, D. rotundata and D. villosa. It is suggested that there are two cotyledons in Dioscorea bulbifera L., D. praehensilis Benth., D. odoratissima Pax., D. hirtiflora Benth., D. preussii Pax., one of which remains in the seed as an absorptive organ. In conclusion, the diagnostic features reported in the wild and micropropagated plants could serve as a basis for proper identification and authentication of D. bulbifera. Bitter Compounds in Tubers of Dioscorea bulbifera L. Journal of Agricultural and Food Chemistry, 22(2): 332-334. Introduction of excised nodal segments from 6 weeks old plant in fresh MS media+BAP (1.0 mg/L)+NAA (0.2 mg/L)+cysteine (2.0 mg/L) resulted in formation of a single bulbil with aerial root after 4 weeks of culturing (Figure 5A). The root tubers are usually absent or insignificant. Copyright © 2020 | First Mag designed by Themes4WP. Some Dioscorea species play an important role in pharmacy. Climate Status The ePub format is best viewed in the iBooks reader. These have been employed in this paper to confirm the identity of the wild and micro propagated samples of D. bulbifera. The purified protein had molecular weight of 21 kDa. In the 1970’s, Pal and Sharma (1979) induced mutations by X-irradiation in D. bulbifera and D. alata with subsequent changes of steroidal sapogenin and alkaloid content in the species. Among the 600 species of the genus Dioscorea, Dioscorea bulbifera has profound therapeutic applications due to its unique phytochemistry. hirtiflora Benth.,D. In Europe D. caucasica and D. pyrenaica are found. A combination of these features had been found useful for taxonomic distinction and recognition in angiosperm families. 1698. Observations on floral morphology of eight species ofDioscorea L., namely,D. Many species have a low rate of flowering and fruit setting and poor seed germination. 9 RAGHUNADAN K, JOLLY C, 1987 Starch from Dioscorea bulbifera. Off A: Nodal segments from green house with elongated shoot and leaves; B: Nodal segments from underground bulbil with elongated shoots and root proliferation. Herein we report the promises of Dioscorea bulbifera and its bioactive principle, diosgenin as novel α-amylase and α-glucosidase inhibitor. The plants are usually climbers, with tubers or rhizomes at the base. Dioscorea bulbifera L., Sp. 7 GUPTA D, SINGH J, 1989 Hydroxy-acetophenone derivatives from Dioscorea bulbifera.

(1943) studied many other wild yams from Central America, such as D. composita, D. testudinatia and D. lobata, with high levels of steroidal sapogenin. Dioscorea bulbifera, Air Potato, Aerial Yam, Potato Yam, Bitter Yam Family. It is commonly called air potato, air yam or bulbil-bearing yam. * Corresponding author.E-mail: anniosuagwu@mail.com. Multiple shoots from subcultured nodal segments. Citation: DIOSCOREA BULBIFERA Linnaeus, Sp. The only exception is D. bulbifera, which, although if has stems twining to the left and globose tuber and forms bulbils, was not found to contain sapogenins. Vegetatively, D. bulbifera is cultivated by planting the whole bulbils, but it is not grown much commercially because of the unpalatable bitter taste[4]. Comparison of mean of parameters of growth using independent student t-test for each column showed no statistical significance at P>0.05. Values are expressed as mean±SEM; 10 replicates per treatment. MS medium was used as the basal medium for shoot and root proliferation. The leaves are shiny green, alternate with a long petiole. Santos L, Thadeo LD, Larema L, Alves RM, Ferreira FA. 1033. Dioscorea bulbifera L. (Family: Dioscoreaceae) commonly known as ‘air potato’ is an important edible medicinal plant use to treat a wide range of diseases. The pH of the medium was adjusted to 5.8 prior to autoclaving. Sarma (1980) studied the influence of diosgenin, isolated from D. prazeri, on chromosomes of Allium cepa. Bulbils and leaves of D. bulbifera were collected in November, 2011 from the field at Alabata village in Moniya, Ibadan, Southwest Nigeria. Morphology and the ability to form microtuber were also found to be unaltered in cryopreserved embryo-derived plantlets. Dioscorea caillei A. Chev. phone: +2348063603103 . Dioscorea belongs to the monocotyledons, family Dioscoreaceae, subfamily Dioscoreoideae. : Aerial yam, Genetic diversity, Morphology, Cluster analyses. Dioscorea bulbifera (Papa aérea): información. Bat. Dioscorea cayenensis has anisocytic stomata, with a percent-age frequency value of 100. In spite of the great medicinal application of D. bulbifera, preference is largely given by local people to the flavor of other yam species. Foundation Project: Supported by University of Ibadan Senate Research Grant (Grant No. From the pharmaceutical point of view, the most important has been the finding that diosgenin production in tissue culture can be at least as high as in intact plants. By using these modern and very accurate methods, it will be possible to apply plant cell cultures to commercial diosgenin production. Mucilages are generally normal products of metabolism formed within the cell (intracellular formation) and or produced without injury to the plant[34]. The species have been the object of numerous studies by botanists, chemists and pharmacists. Better diosgenin production may also be achieved by addition of mycelia of some fungal species to the culture, a technique that seems be very promising. Dioscorea bulbifera is an edible yam species differentiated from every other species by the possession of specialized aerial bulbils, usually produced on the base of petioles (Martin, 1974). 600 species and is divisible into numerous sections according to stem twining, leaf morphology, inflorescences, seed wings, bulbil formation, tuber morphology and chemical content. Suitable pH: acid, neutral and basic (alkaline) soils and can grow in very acid and very alkaline soils. Ivanova T, Gussev C, Bosseva Y, Stoeva T. Soares JD, Pasqual M, De Araujo AG, De Castro EM, Pereira FJ, Braga FT. Stem-Twining to the left, unarmed, often with bulbils in the leaf-axils. Comparative qualitative and quantitative features of foliar epidermis of wild and micropropagated D. bulbifera are presented in Table 3. To study the leaf epidermis of wild and micropropagated Dioscorea bulbifera Linn. Subculturing of nodal segments of D. bulbifera obtained from Figure 3A and ​and3B3B after 6 weeks of growth in the same media resulted in formation of multiple shoots, 3.60±0.87 [mean length (49.20±5.71) mm] within 6 weeks of culturing, which was higher compared to multiple shoots, 2.40±0.40 [mean length of (33.60±7.48) mm] (Table 2) obtained from excised nodal segments from green house (Figure 4A and ​and4B4B). Slides were examined for assessment of the qualitative diagnostic features such as stomata type, cuticular striation on walls, mucilage and shape of epidermal cell with quantitative parameters such as epidermal cell size, stomata and epidermal wall dimension were recorded. The cultures were incubated at (27±1) °C with a photoperiod of 16 h at an intensity of 10-20 µmol m−2s−1. In water saturated flask atmosphere such as the one presented in tissue culture experiments, the accumulation of specific gases (ethylene) in the confined atmosphere causes a dramatic increase in the transpiration rate leading to the failure of stomata to close[46]. (1969) found that D. floribunda leaf homogenate converted the open-chain glycoside of diosgenin to dioscin. Shoot and root proliferation were scored and measured after 6 weeks of culturing. Among petroleum ether, ethyl acetate, methanol and 70% ethanol (v/v) extracts of bulbs of D. bulbifera, ethyl acetate extract showed highest inhibition upto 72.06 ± 0.51% and 82.64 ± 2.32% against α-amylase and α-glucosidase respectively. It is widely cultivated and has become naturalized in many regions (Latin America, the West Indies, the Southeastern United States, and various oceanic islands). Stem-Twining to the left, unarmed, often with bulbils in the leaf-axils. As with many species within the genus Dioscorea, D. bulbifera does not support its own weight to any great height and in order to capture sunlight, this species has evolved to climb by twining on other plants (Florida Exotic Pest Plant Council, 2008). Morphology Dioscorea bulbifera is a vigorously twining, long-stemmed perennial vine with non-spiny stems to 20 m or more in length, freely branching above; internodes round or slightly angled in cross section and they twine counter-clockwise.
