Using diversity indices (Shannon-Wiener), plant knowledge is compared among communities (urban- rural population), and between sex (male-female) and age (older or younger than 40 years) categories within each community. Among our informants, we found quantitative differences concerning the knowledge of medicinal plants between sex and age categories. Some individuals play a key role relating to medicinal plant knowledge, and steps should be taken in order to include them in management and conservation plans. Key words: ethnobotany, diversity indices, plant knowledge and use, Rio Negro, Brazilian Amazon.

  • The Evolutionary Fate of Rpl32 and Rps16 Losses in the Euphorbia Schimperi (Euphorbiaceae) Plastome Aldanah A
    www.nature.com/scientificreports OPEN The evolutionary fate of rpl32 and rps16 losses in the Euphorbia schimperi (Euphorbiaceae) plastome Aldanah A. Alqahtani1,2* & Robert K. Jansen1,3 Gene transfers from mitochondria and plastids to the nucleus are an important process in the evolution of the eukaryotic cell. Plastid (pt) gene losses have been documented in multiple angiosperm lineages and are often associated with functional transfers to the nucleus or substitutions by duplicated nuclear genes targeted to both the plastid and mitochondrion. The plastid genome sequence of Euphorbia schimperi was assembled and three major genomic changes were detected, the complete loss of rpl32 and pseudogenization of rps16 and infA. The nuclear transcriptome of E. schimperi was sequenced to investigate the transfer/substitution of the rpl32 and rps16 genes to the nucleus. Transfer of plastid-encoded rpl32 to the nucleus was identifed previously in three families of Malpighiales, Rhizophoraceae, Salicaceae and Passiforaceae. An E. schimperi transcript of pt SOD-1- RPL32 confrmed that the transfer in Euphorbiaceae is similar to other Malpighiales indicating that it occurred early in the divergence of the order. Ribosomal protein S16 (rps16) is encoded in the plastome in most angiosperms but not in Salicaceae and Passiforaceae. Substitution of the E. schimperi pt rps16 was likely due to a duplication of nuclear-encoded mitochondrial-targeted rps16 resulting in copies dually targeted to the mitochondrion and plastid. Sequences of RPS16-1 and RPS16-2 in the three families of Malpighiales (Salicaceae, Passiforaceae and Euphorbiaceae) have high sequence identity suggesting that the substitution event dates to the early divergence within Malpighiales.

INTRODUCTION 1. Context The overall aim of ARCAD (Agropolis Resource Centre for Crop Conservation, Adaptation and Diversity) is to set up an open multi-function platform devoted to the assessment and improved use of plant agrobiodiversity in Mediterranean and tropical regions. It is being jointly implemented by CIRAD, INRA, IRD and Montpellier SupAgro and is supported by Agropolis Fondation and the Languedoc-Roussillon Region. The ARCAD concept was developed in 2007-2008, but it is rooted in a much older overall ambition of research and higher education institutions (mainly INRA, CIRAD, IRD and Montpellier SupAgro) to give Montpellier-Languedoc Roussillon Region world-wide visibility in the field of agrobiodiversity, plant genetics and genomics.

  • Revision of Annesijoa, Elateriospermum and the Introduced Species of Hevea in Malesia (Euphorbiaceae)
    BLUMEA 49: 425– 440 Published on 10 December 2004 doi: 10.3767/000651904X484351 REVISION OF ANNESIJOA, ELATERIOSPERMUM AND THE INTRODUCED SPECIES OF HEVEA IN MALESIA (EUPHORBIACEAE) HOANG VAN SAM1 & PETER C. vaN WELZEN2 SUMMARY Annesijoa is an endemic monotypic genus from New Guinea with as single species A. novoguineensis. Elateriospermum is also monotypic (E. tapos) and found in West Malesia. The South American genus Hevea comprises about 10 species. One species (H. brasiliensis) is presently cultivated worldwide in plantations for its rubber and has become one of the major economic products of SE Asia. Two other species, H. guianensis and H. pauciflora are sometimes present in Malesian botanical gardens. Key words: Euphorbiaceae, Annesijoa, Elateriospermum, Hevea, Malesia. INTRODUCTION Three genera are revised for Flora Malesiana, Annesijoa Pax & K. Hoffm., Elaterio­ spermum Blume, and Hevea Aubl. These genera are not very closely related, but they are all part of the subfamily Crotonoideae (Webster, 1994; Radcliffe-Smith, 2001), though classified in different tribes (Jatropheae, Elateriospermeae, and Micrandreae subtribe Heveinae, respectively). Typical for the Micrandreae are colporate pollen with a reticulate sexine, articulate laticifers, absent petals, and plenty of endosperm (oily in the Heveinae). The Jatropheae and Elateriospermeae share inaperculate pollen with a typical ‘crotonoid’ sexine, inarticulate laticifers, petals absent or not, and seeds with or without endosperm. They differ in several characters, the Elateriospermeae lack endosperm and have no petals, while these are present in the Jatropheae. The three genera can easily be distinguished from each other. Hevea and Elaterio­ spermum have white latex, whereas Annesijoa has variable latex ranging from clear to white to red.

In this chapter, we attempt to describe the major types of vegetation cover in this vast region as they occurred in pre- Columbian times and outline the conditions that support them. Examining the large-scale phytogeographic regions characterized by each major cover type (see Fig. I), we provide basic information on geology, geological history, topography, and climate; describe variants of physiognomy (vegetation structure) and geography; discuss transitions; and examine some floristic patterns and affinities within and among these regions.
