PLANT KINGDOM Amongst plants nearly 15,000 species belong to Mosses and Liverworts, 12,700 Ferns and their allies, 1,079 Gymnosperms and 295,383 Angiosperms (belonging to about 485 families and 13,372 genera), considered to be the most recent and vigorous group of plants that have occurred on earth. Angiosperms occupy the majority of the terrestrial space on earth, and are the major components of the world‘s vegetation. Brazil (First) and Colombia (second), both located in the tropics considered to be countries with the most diverse angiosperms floras China (Third) even though the main part of her land is not located in the tropics, the number of angiosperms still occupies the third place in the world. In INDIA there are about 18042 species of flowering plants approximately 320 families, 40 genera and 30,000 species. IUCN Red list Categories: EX –Extinct; EW- Extinct in the Wild-Threatened; CR -Critically Endangered; VU- Vulnerable Angiosperm (Flowering Plants) SPECIES RICHNESS AROUND THE WORLD PLANT CLASSIFICATION Historia Plantarum - the earliest surviving treatise on plants in which Theophrastus listed the names of over 500 plant species. Artificial system of Classification Theophrastus attempted common groupings of folklore combined with growth form such as ( Tree Shrub; Undershrub); or Herb. Or (Annual and Biennials plants) or (Cyme and Raceme inflorescences) or (Archichlamydeae and Meta chlamydeae) or (Upper or Lower ovarian ).

  • White Lead Tree (Leucaena Leucocephala)
    UF/IFAS Extension Hernando County Fact Sheet 2015-03 White Lead Tree (Leucaena leucocephala) Dr. William Lester, Extension Agent II • Email: [email protected] Lead tree is the common name for all members of the Leucaena genus. White lead tree refers to this particular tree’s whitish blossoms. The lead tree is native to Mexico and Central America, but it is cultivated throughout the tropics, and it has widely escaped and naturalized. In the United States, it has been reported as an adventive from Arizona, California, Florida, Hawaii, Puerto Rico, Texas and the Virgin Islands. In Hernando County the tree is mostly located along the coast, but has been found growing in alkaline soils further inland. White lead tree grows best in full sunlight and can reach heights of up to 60 feet. The leaves are alternately arranged, bipinnately compound, and typically 10 inches in length. Each leaflet is ½ inch long and spear-shaped. The bark is lightly textured and grayish-brown in color when mature. Flowers are white and grow in globe-shaped clusters at the ends of the branches, with each cluster being less than 1 inch wide. Fruits are 4- to 6-inch-long, flat pods that are 1–2 inches wide. Pods have raised edges, turn from green to brown with maturity, and contain 10–30 oval-shaped, brown seeds. In Florida, white leadtree is considered a category II invasive species, and has the potential to displace native plant communities because it is an aggressive competitor for resources. As a result, the Division of Plant Industry strictly prohibits possessing (including collecting), transporting (including importing), and cultivating this species.

Page 1 of 51 P.PSH.1055 – Desmanthus and methane emissions Abstract Methane is a greenhouse gas produced as a by-product of fermentation of feedstuffs in ruminants. Desmanthus is a tropical legume adapted to parts of northern Australia. Laboratory studies have demonstrated that Desmanthus can reduce the production of methane when incubated with rumen fluid. The objective of this project was to determine if methane production could be reduced by feeding Desmanthus to cattle and to provide data to support a methodology allowing the avoided emissions to be traded in the carbon market. Several cultivars developed by JCU and Agrimix Pastures Pty Ltd were tested in three cattle feeding trials.

  • Genome of Rhizobium Leucaenae Strains CFN 299T and CPAO 29.8
    Ormeño-Orrillo et al. BMC Genomics (2016) 17:534 DOI 10.1186/s12864-016-2859-z RESEARCHARTICLE Open Access Genome of Rhizobium leucaenae strains CFN 299T and CPAO 29.8: searching for genes related to a successful symbiotic performance under stressful conditions Ernesto Ormeño-Orrillo1†, Douglas Fabiano Gomes2,3†, Pablo del Cerro4, Ana Tereza Ribeiro Vasconcelos5, Carlos Canchaya6, Luiz Gonzaga Paula Almeida5, Fabio Martins Mercante7, Francisco Javier Ollero4, Manuel Megías4 and Mariangela Hungria2* Abstract Background: Common bean (Phaseolus vulgaris L.) is the most important legume cropped worldwide for food production and its agronomic performance can be greatly improved if the benefits from symbiotic nitrogen fixation are maximized. The legume is known for its high promiscuity in nodulating with several Rhizobium species, but those belonging to the Rhizobium tropici “group” are the most successful and efficient in fixing nitrogen in tropical acid soils. Rhizobium leucaenae belongs to this group, which is abundant in the Brazilian “Cerrados” soils and frequently submitted to several environmental stresses. Here we present the first high-quality genome drafts of R. leucaenae, including the type strain CFN 299T and the very efficient strain CPAO 29.8. Our main objective was to identify features that explain the successful capacity of R. leucaenae in nodulating common bean under stressful environmental conditions. Results: The genomes of R. leucaenae strains CFN 299T and CPAO 29.8 were estimated at 6.7–6.8 Mbp; 7015 and 6899 coding sequences (CDS) were predicted, respectively, 6264 of which are common to both strains. The genomes of both strains present a large number of CDS that may confer tolerance of high temperatures, acid soils, salinity and water deficiency.

(2012). Leucaena leucocephala (Lam.) de Wit es una de las especies más utilizadas en los sistemas silvopastoriles tropicales, por su rápido crecimiento, su capacidad de mejoras el suelo y el gran contenido proteico. Es a su vez una de las especies invasoras más agresivas a nivel mundial (Lowe & al., 2004), formando matorrales monoespecíficos difíciles de eliminar, por su gran producción de semillas y capacidad de regeneración. Esta especie en Cuba invade terrenos de cultivo abandonados, áreas abiertas de vegetación secundaria, totalmente deforestadas o seminaturales, donde forma densos bosques, dificulta la reutilización de estas áreas en otras labores agrícolas, ganaderas o el establecimiento de la vegetación nativa (Fuentes & González, 2011 ). Este documento persigue el objetivo de establecer un protocolo para el monitoreo de la especie en Cuba, con el objetivo de evaluar la efectividad de las acciones de manejo sobre la misma. CARACTERIZACIÓN DE LA ESPECIE Nombre científico: Leucaena leucocephala (Lam.) de Wit Clasificacación taxonómica superior de la especie: Género: Leucaena, Familia: Fabaceae (Leguminosae), Orden: Fabales, División: Magnoliophyta.

  • Leucaena Leucocephala (Lam.) De
    Leucaena leucocephala (Lam.) De wit Leucaena leucocephala The fast-growing, nitrogen-fixing tree/shrub is cultivated as a fodder plant, for green manure, as a windbreak, for reforestation, as a biofuel crop etc. Leucaena has been widely introduced due to its beneficial qualities; it has become an aggressive invader in disturbed areas in many tropical and sub-tropical locations and is listed as one of the ‘100 of the World’s Worst Invasive Alien Species’. Leucaena is a prolific bearer of seeds (up-to 1700 pods per tree with each pod containing 20 seeds with 2-3 cycles per year); seeds are dispersed by rodents, birds and naturally. It forms dense monotypic stands in disturbed areas that it invades preventing the establishment of native plant species. It also excludes plant growth in its vicinity by an allelopathic effect caused by a chemical Ek Balam it produces called mimosine. Young leaves and mature seeds have Photo Credit: Wikimedia commons (User: ) a high mimosine content. Leucaena was introduced to the Bonin Ogasawara Islands in 1862 Leucaena is one of several invasive alien plants that are a threat and has had negative impacts on the native plant communities; to the highly threatened sclerophyll forests in New Caledonia, in disturbed areas it invades early in succession preventing dominating open and secondary forests.

  • Synoptic Overview of Exotic Acacia, Senegalia and Vachellia (Caesalpinioideae, Mimosoid Clade, Fabaceae) in Egypt
    plants Article Synoptic Overview of Exotic Acacia, Senegalia and Vachellia (Caesalpinioideae, Mimosoid Clade, Fabaceae) in Egypt Rania A. Hassan * and Rim S. Hamdy Botany and Microbiology Department, Faculty of Science, Cairo University, Giza 12613, Egypt; [email protected] * Correspondence: [email protected] Abstract: For the first time, an updated checklist of Acacia, Senegalia and Vachellia species in Egypt is provided, focusing on the exotic species. Taking into consideration the retypification of genus Acacia ratified at the Melbourne International Botanical Congress (IBC, 2011), a process of reclassification has taken place worldwide in recent years. The review of Acacia and its segregates in Egypt became necessary in light of the available information cited in classical works during the last century. In Egypt, various taxa formerly placed in Acacia s.l., have been transferred to Acacia s.s., Acaciella, Senegalia, Parasenegalia and Vachellia. The present study is a contribution towards clarifying the nomenclatural status of all recorded species of Acacia and its segregate genera. This study recorded 144 taxa (125 species and 19 infraspecific taxa). Only 14 taxa (four species and 10 infraspecific taxa) are indigenous to Egypt (included now under Senegalia and Vachellia). The other 130 taxa had been introduced to Egypt during the last century. Out of the 130 taxa, 79 taxa have been recorded in literature. The focus of this study is the remaining 51 exotic taxa that have been traced as living species in Egyptian gardens or as herbarium specimens in Egyptian herbaria. The studied exotic taxa are accommodated under Acacia s.s. (24 taxa), Senegalia (14 taxa) and Vachellia (13 taxa).
