Micropropagation of Selected Agave Species
Micropropagation of selected Agave species Dariusz KULUS∗ Keywords: CAM; in vitro regeneration; plant tissue culture Abstract: Agaves are a very important group of plants. They are popular ornamentals but they are also used in the production of drugs, cosmetics, drinks, food and fodder. Unfortunately, due to the growing influence of anthropopressure, some of them are threaten with extinction. Therefore, in order to always be able to meet the growing demands of the market, novel biotechnolog- ical tools need to be applied in the production of these species. Micropropagation, i.e. vegetative multiplication of plants under aseptic, strictly controlled conditions and with the use of syn- thetic media, is the most commonly applied aspect of plant tissue cultures. The technique reduces time, space and costs required for the production of plants. Over time, several micropropaga- tion techniques have been developed also with agaves. The aim of the present review is to present the current achievements and problems associated with micropropagation of the most impor- tant agave species. 1. Introduction: origin and uses The genus Agave contains 155 species (and over 200 varieties) of the Agavaceae family, 75 % of which are native to Mexico. They are found from South America northwards to Mexico, and beyond to the southern States of America, as well as up to the coast of California, and in the Caribbean Islands. The genus was established by Linnaeus in 1753 (Debnath et al., 2010). Agave has been a renewable source for food, beverages (tequila), fibers (sisal), silage for livestock, drugs (saponins, sterols, steroidal alkaloids, alkaloidalamines), ornamental plants (due to their distinctive leaf form and color) and other useful products. -
Origin of the Cyathium-Bearing Euphorbieae (Euphorbiaceae): Phylogenetic Study Based on Morphological Characters
ParkBot. Bull.and Backlund Acad. Sin. — (2002) Origin 43: of 57-62 the cyathium-bearing Euphorbieae 57 Origin of the cyathium-bearing Euphorbieae (Euphorbiaceae): phylogenetic study based on morphological characters Ki-Ryong Park1,* and Anders Backlund2 1Department of Biology, Kyung-Nam University, Masan 631-701, Korea 2Division of Pharmacognosy, Department of Pharmacy, Uppsala University, BMC-Biomedical center, S-751 23 Uppsala, Sweden (Received October 6, 2000; Accepted August 24, 2001) Abstract. A cladistic analysis of the subfamily Euphorbioideae was undertaken to elucidate the origin of the cyathium- bearing Euphorbieae and to provide hypotheses about evolutionary relationships within the subfamily. Twenty-one species representing most of the genera within the study group and three outgroup taxa from the subfamilies Acalyphoideae and Crotonoideae were selected for parsimony analysis. An unweighted parsimony analysis of 24 morphological characters resulted in five equally parsimonious trees with consistency indices of 0.67 and tree lengths of 39 steps. The strict consensus tree supported monophyly of the cyathium-bearing Euphorbieae. The sister group relationships of cyathium bearing Euphorbieae with Maprounea (subtribe Hippomaninae) were supported weakly, and the origin of cyathium is possibly in Hippomaneae, or in the common ancestor of Euphorbieae and remaining taxa of Euphorbioideae plus Acalyphoideae. Within the tribe Euphorbieae, both subtribes Euphorbiinae and Neoguilauminiinae are monophyletic, but the African endemic subtribe Anthosteminae is unresolved. The resulting trees support the monophyly of the tribe Stomatocalyceae while the tribe Hippomaneae does not consistently form a clade. Keywords: Cyathium; Euphorbieae; Phylogeny.

Address for correspondence: Nicolás García, [email protected] DOI https://doi.org/10.1002/tax.12062 Abstract A robust generic classification for Amaryllidaceae has remained elusive mainly due to the lack of unequivocal diagnostic characters, a consequence of highly canalized variation and a deeply reticulated evolutionary history. A consensus classification is pro- posed here, based on recent molecular phylogenetic studies, morphological and cytogenetic variation, and accounting for secondary criteria of classification, such as nomenclatural stability. Using the latest sutribal classification of Hippeastreae (Hippeastrinae and Traubiinae) as a foundation, we propose the recognition of six genera, namely Eremolirion gen. nov., Hippeastrum, Phycella s.l., Rhodolirium s.str., Traubia, and Zephyranthes s.l. A subgeneric classification is suggested for Hippeastrum and Zephyranthes to denote putative subclades. -
Biochemical Assessment of the Effect of Aqueous Leaf Extract of Euphorbia Heterophylla Linn on Hepatocytes of Rats

Volume 3, Issue 5 (Mar. - Apr. 2013), PP 37-41 www.Iosrjournals.Org Biochemical Assessment of the Effect of Aqueous Leaf Extract Of Euphorbia Heterophylla Linn on Hepatocytes of Rats Apiamu Augustine1, Evuen Uduenevwo Francis 2, Ajaja Uche Ivy3 1, 2 & 3( Department of Biochemistry, College of Natural and Applied Sciences, Western Delta University, Nigeria) Abstract: In recent years, the search for biologically active compounds from Euphorbia heterophylla in the treatment of different diseases has always been of great interest to researchers. In this present study, we investigated the effect of the aqueous leaf extract of the plant on hepatocytes using animal models. A total of twenty (20) wistar albino rats (150-240g) were used for the study. The rats were randomly divided into four experimental groups (A, B, C & D) comprising five rats per group. The control group was administered deionised water while the treatment groups were orally administered doses of the aqueous leaf extract of the plant( 100mg/kg, 200mg/kg and 300mg/kg body weights) by means of a gavage for two weeks. Total protein, albumin, urea nitrogen, alanine aminotransferase(ALT), aspartate aminotransferase(AST) and alkaline phosphatase(ALP) were the biochemical parameters assessed in this study. The results showed no significant difference(p>0.05 in the levels of the aforementioned parameters. The aqueous leaf extract of the plant indicated the presence of carbohydrates, saponins, tannins, flavonoids, alkaloids, terpenoids and steroids, but anthracene derivatives were absent. The results obtained in this study, therefore, justify the traditional use of the plant for food and medicinal purposes respectively. -

Author for correspondence: Paul E. Berry, [email protected] Abstract Euphorbia subg. Chamaesyce contains around 600 species and includes the largest New World radiation within the Old World-centered genus Euphorbia. It is one of the few plant lineages to include members with C3, C4 and CAM photosyn- thesis, showing multiple adaptations to warm and dry habitats. The subgenus includes North American-centered groups that were previously treated at various taxonomic ranks under the names of “Agaloma ”, “Poinsettia ”, and “Chamaesyce ”. Here we provide a well-resolved phylogeny of Euphorbia subg. Chamaesyce using nuclear ribosomal ITS and chloroplast ndhF sequences, with substantially increased taxon sampling compared to previous studies. Based on the phylogeny, we discuss the Old World origin of the subgenus, the evolution of cyathial morphology and growth forms, and then provide a formal sectional classification, with descriptions and species lists for each section or subsection we recognize. -

IAWA Journal, Vol. 26 (1), 2005: 1-68 WOOD ANATOMY OF THE SUBFAMILY EUPHORBIOIDEAE A comparison with subfamilies Crotonoideae and Acalyphoideae and the implications for the circumscription of the Euphorbiaceae Alberta M. W. Mennega Nationaal Herbarium Nederland, Utrecht University branch, Heidelberglaan 2, 3584 es Utrecht, The Netherlands SUMMARY The wood anatomy was studied of 82 species from 34 out of 54 genera in the subfamily Euphorbioideae, covering all five tribes recognized in this subfamily. In general the woods show a great deal of similarity. They are charac terized by a relative paucity of vessels, often arranged in short to long, dumbbell-shaped or twin, radial multiples, and by medium-sized to large intervessel pits; fibres often have gelatinous walls; parenchyma apotracheal in short, wavy, narrow bands and diffuse-in-aggregates; mostly uni- or only locally biseriate rays, strongly heterocellular (except Hippomane, Hura and Pachystroma). Cell contents, either silica or crystals, or both together, are nearly always present and often useful in distinguishing between genera. Radiallaticifers were noticed in most genera, though they are scarce and difficult to trace. The laticifers are generally not surrounded by special cells, except in some genera of the subtribe Euphorbiinae where radiallaticifers are comparatively frequent and conspicuous. Three ofthe five tribes show a great deal of conformity in their anatomy. Stomatocalyceae, however, stand apart from the rest by the combination of the scarcity of vessels, and mostly biseriate, vertically fused and very tall rays. Within Euphorbieae the subtribe Euphorbiinae shows a greater vari ation than average, notably in vessel pitting, the frequent presence of two celled parenchyma strands, and in size and frequency of the laticifers. -

An increasing number is escaping and naturalising, also in natural habitats in the Canary Islands (Spain). However, a detailed treatment of variously naturalised and invasive species found in the wild in the Canary Islands is not available and, as a result, species identification is often problematic.
