Srnitli / ·H IV l ohn Krc:}s,3 and Z 3 THE ZING IBERALES BASED I:'/izabeth A. Zimmer • ON rbeL SEQUENCES' AnSTRAcr Morphological data have bet:n used previously to construct phylogenies of the eight families of the Zingiberales, one of the most wi dely accepted monophyletic groups of nowcring plants. To provide additional suppon for phylogenetic relationships within Ihe order, and placement of the order among monacots. we present a parsimony analysis of DNA sequences from the chloroplast-encoded gene, rbe L. for 21 species of Zingiberales and proposed relatives. Five analyses with equal, and differential weights were performed. All analyses resulted in the salllC most parsimonious tree for taxa within the Zingiberales and the irnmediate outgroup. The closest sister group to the Zingiberales based on these data is a clade containing Commelinaceae/ Haemodoraceae/ Pontederiaceae. The tree topology within the order based on r/)('l sequence data is different from previous morphological analyses. The order can be divided into two sister groups, one containing the Costaceae and Marantaceae, and the other, the remaining six families . All recognized families are monophyletic with the exception of the Musaceae, which is paraphyletic with the Cannaceae. With trees one and two steps longer than the most parsimonious trees, phylogenetic resolution is rapidly lost. suggesting that the phylogenetic utility of rbe l sequence data for the Zingiberales is limited to interordinal and intrafamilial relationships.

Ensete ventricosum is a traditional multipurpose crop mainly used as a staple/co-staple food for over 20 million people in Ethiopia. Despite this, scientific information about the crop is scarce. (ree types of food, viz., Kocho (fermented product from scraped pseudostem and grated corm), Bulla (dehydrated juice), and Amicho (boiled corm) can be prepared from enset. (ese products are particularly rich in carbohydrates, minerals, fibres, and phenolics, but poor in proteins. Such meals are usually served with meat and cheese to supplement proteins. As a food crop, it has useful attributes such as foods can be stored for long time, grows in wide range of environments, produces high yield per unit area, and tolerates drought. It has an irreplaceable role as a feed for animals. Enset starch is found to have higher or comparable quality to potato and maize starch and widely used as a tablet binder and disintegrant and also in pharmaceutical gelling, drug loading, and release processes.

  • Well-Known Plants in Each Angiosperm Order
    Well-known plants in each angiosperm order This list is generally from least evolved (most ancient) to most evolved (most modern). (I’m not sure if this applies for Eudicots; I’m listing them in the same order as APG II.) The first few plants are mostly primitive pond and aquarium plants. Next is Illicium (anise tree) from Austrobaileyales, then the magnoliids (Canellales thru Piperales), then monocots (Acorales through Zingiberales), and finally eudicots (Buxales through Dipsacales). The plants before the eudicots in this list are considered basal angiosperms. This list focuses only on angiosperms and does not look at earlier plants such as mosses, ferns, and conifers. Basal angiosperms – mostly aquatic plants Unplaced in order, placed in Amborellaceae family • Amborella trichopoda – one of the most ancient flowering plants Unplaced in order, placed in Nymphaeaceae family • Water lily • Cabomba (fanwort) • Brasenia (watershield) Ceratophyllales • Hornwort Austrobaileyales • Illicium (anise tree, star anise) Basal angiosperms - magnoliids Canellales • Drimys (winter's bark) • Tasmanian pepper Laurales • Bay laurel • Cinnamon • Avocado • Sassafras • Camphor tree • Calycanthus (sweetshrub, spicebush) • Lindera (spicebush, Benjamin bush) Magnoliales • Custard-apple • Pawpaw • guanábana (soursop) • Sugar-apple or sweetsop • Cherimoya • Magnolia • Tuliptree • Michelia • Nutmeg • Clove Piperales • Black pepper • Kava • Lizard’s tail • Aristolochia (birthwort, pipevine, Dutchman's pipe) • Asarum (wild ginger) Basal angiosperms - monocots Acorales

  • Outline of Angiosperm Phylogeny
    Outline of angiosperm phylogeny: orders, families, and representative genera with emphasis on Oregon native plants Priscilla Spears December 2013 The following listing gives an introduction to the phylogenetic classification of the flowering plants that has emerged in recent decades, and which is based on nucleic acid sequences as well as morphological and developmental data. This listing emphasizes temperate families of the Northern Hemisphere and is meant as an overview with examples of Oregon native plants. It includes many exotic genera that are grown in Oregon as ornamentals plus other plants of interest worldwide. The genera that are Oregon natives are printed in a blue font. Genera that are exotics are shown in black, however genera in blue may also contain non-native species. Names separated by a slash are alternatives or else the nomenclature is in flux. When several genera have the same common name, the names are separated by commas. The order of the family names is from the linear listing of families in the APG III report. For further information, see the references on the last page.

(Strelitziaceae), a native of South Africa, is newly recorded as a sparingly naturalised weed for New South Wales and represents new family, generic and species records for the state. Descriptions, notes and identification key are provided for the family, genus and species. Introduction Strelitzia nicolai Regel & Körn. (Giant White Bird of Paradise or Natal Wild Banana; Strelitziaceae), a native of South Africa, is a common horticultural subject in eastern Australia. Recently a small colony of plants was discovered at Minnie Water (c. 60 km NNE of Coffs Harbour, North Coast, New South Wales). The colony is of note as some plants were 8 m tall (suggesting they had been there for some time) and that they were setting viable seed. Seedlings were found within this population and Milne and Luxton have observed that the species is being found in increasing numbers on council land and in National Parks of the area.

    URL: http://www.iupac.org/symposia/proceedings/phuket97/sirirugsa.html © 1999 IUPAC Thai Zingiberaceae : Species Diversity And Their Uses Puangpen Sirirugsa Department of Biology, Faculty of Science, Prince of Songkla University, Hat Yai, Thailand Abstract: Zingiberaceae is one of the largest families of the plant kingdom. It is important natural resources that provide many useful products for food, spices, medicines, dyes, perfume and aesthetics to man. Zingiber officinale, for example, has been used for many years as spices and in traditional forms of medicine to treat a variety of diseases. Recently, scientific study has sought to reveal the bioactive compounds of the rhizome. It has been found to be effective in the treatment of thrombosis, sea sickness, migraine and rheumatism. GENERAL CHARACTERISTICS OF THE FAMILY ZINGIBERACEAE Perennial rhizomatous herbs. Leaves simple, distichous. Inflorescence terminal on the leafy shoot or on the lateral shoot. Flower delicate, ephemeral and highly modified. All parts of the plant aromatic. Fruit a capsule. HABITATS Species of the Zingiberaceae are the ground plants of the tropical forests. They mostly grow in damp and humid shady places. They are also found infrequently in secondary forest. Some species can fully expose to the sun, and grow on high elevation. DISTRIBUTION Zingiberaceae are distributed mostly in tropical and subtropical areas. The center of distribution is in SE Asia. The greatest concentration of genera and species is in the Malesian region (Indonesia, Malaysia, Singapore, Brunei, the Philippines and Papua New Guinea) *Invited lecture presented at the International Conference on Biodiversity and Bioresources: Conservation and Utilization, 23–27 November 1997, Phuket, Thailand.

  • Full of Beans: a Study on the Alignment of Two Flowering Plants Classification Systems
    Full of beans: a study on the alignment of two flowering plants classification systems Yi-Yun Cheng and Bertram Ludäscher School of Information Sciences, University of Illinois at Urbana-Champaign, USA {yiyunyc2,ludaesch}@illinois.edu Abstract. Advancements in technologies such as DNA analysis have given rise to new ways in organizing organisms in biodiversity classification systems. In this paper, we examine the feasibility of aligning two classification systems for flowering plants using a logic-based, Region Connection Calculus (RCC-5) ap- proach. The older “Cronquist system” (1981) classifies plants using their mor- phological features, while the more recent Angiosperm Phylogeny Group IV (APG IV) (2016) system classifies based on many new methods including ge- nome-level analysis. In our approach, we align pairwise concepts X and Y from two taxonomies using five basic set relations: congruence (X=Y), inclusion (X>Y), inverse inclusion (X<Y), overlap (X><Y), and disjointness (X!Y). With some of the RCC-5 relationships among the Fabaceae family (beans family) and the Sapindaceae family (maple family) uncertain, we anticipate that the merging of the two classification systems will lead to numerous merged solutions, so- called possible worlds. Our research demonstrates how logic-based alignment with ambiguities can lead to multiple merged solutions, which would not have been feasible when aligning taxonomies, classifications, or other knowledge or- ganization systems (KOS) manually. We believe that this work can introduce a novel approach for aligning KOS, where merged possible worlds can serve as a minimum viable product for engaging domain experts in the loop. Keywords: taxonomy alignment, KOS alignment, interoperability 1 Introduction With the advent of large-scale technologies and datasets, it has become increasingly difficult to organize information using a stable unitary classification scheme over time.
