J Adv Plant Sci 1: 201 Article history: Received: 26 May 2018, Accepted: 30 July 2018, Published: 02 August 2018 Abstract District Kachchh, despite having arid climate and long coastline, can be considered as biologically rich region. For the present study the floristic surveys of both inland and coastal plants were carried out during July 2011 to October 2012, which resulted in record of total of 203 angiosperm taxa. They fall under 145 genera and 57 families. Out of that 102 halophytic species were recorded during rapid survey that belongs to 53 genera and 37 families. The dominant families were Poaceae (16 taxa), Asteraceae, Cyperaceae, and Chenopodiaceae present with seven taxa. Kachchh represents mainly one worst invasive exotic species namely Prosopis jullflora, which may pose survival threat to the indigenous flora. Out of these, 74 species distributed predominantly among xerohalophytic communities naturally and 28 hydrohalophytic have been listed by present survey with special reference to their life form and main localities of their distribution. Keywords: Vegetation; Flora; Halophyte; Kachchh; Coastal Introduction Halophytes are defined as plants that naturally inhabit saline environments and benefit from having substantial amounts of salt in the growth media. -

S. M. El Naggar & N. Sawady Pollen Morphology of Malvaceae and its taxonomic significance in Yemen Abstract El Naggar, S. M. & Sawady N.: Pollen Morphology of Malvaceae and its taxonomic signifi- cance in Yemen. — Fl. Medit. 18: 431-439. 2008. — ISSN 1120-4052. The pollen morphology of 20 species of Malvaceae growing in Yemen was investigated by light (LM) and scanning electron microscope (SEM). The studied taxa belong to 9 genera and three different tribes. These taxa are: Abelmoschus esculentus, Hibiscus trionum, H. micranthus, H. deflersii, H. palmatus, H. vitifolius, H. rosa-sinensis, H. ovalifolius, Gossypium hirsutum, Thespesia populnea (L.) Solander ex Correa and Senra incana (Cav.) DC. (Hibiscieae); Malva parviflora and Alcea rosea (Malveae); Abutilon fruticosum, A. figarianum, A. bidentatum, A. pannosum, Sida acuta, S. alba and S. ovata (Abutileae). Pollen shape, size, aperture, exine structure and sculpturing as well as the spine characters proved that they are of high taxonom- ic value. Pollen characters with some other morphological characters are discussed in the light of the recent classification of the family in Yemen. Key words: Malvaceae, Morphology, Yemen. Introduction Malvaceae Juss. (s. str.) is a large family of herbs, shrubs and trees; comprising about 110 genera and 2000 species. It is a globally distributed family with primary concentrations of genera in the tropical and subtropical regions (Hutchinson 1967; Fryxell 1975, 1988 & 1998; Heywood 1993; La Duke & Doeby 1995; Mabberley 1997). Due to the high economic value of many taxa of Malvaceae (Gossypium, Hibiscus, Abelmoschus and Malva), several studies of different perspective have been carried out, such as those are: Edlin (1935), Bates and Blanchard (1970), Krebs (1994a, 1994b), Ray (1995 & 1998), Hosni and Araffa (1999), El Naggar (1996, 2001 & 2004), Pefell & al. -

It is a predominantly flat land with several shallow depressions, which act as seasonal wetlands after monsoon and during winter its converts into sedge mixed grassland, an ideal dual ecosystem. An attempt was made to document ecology, biomass and community based assessment of grasses in Banni, we surveyed systematically and recorded a total of 49 herbaceous plant species, being used as fodder by livestock. In which, the maximum numbers of species (21 Nos.) were recorded in Echinocloa and Cressa habitat; followed by Sporobolus and Elussine habitat (20 species); and Desmostechia-Aeluropus and Cressa habiat (19 species). A total of 21 highest palatable species were recorded in Echinocloa-Cressa communities followed by Sporobolus-Elussine–Desmostechia (20 species and 18 palatable species) and Aeluropus–Cressa (19 species and 17 palatable species). For long-term conservation of Banni grassland, we also suggest a participatory co-management plan.

The University of British Columbia Vancouver, Canada http://www.library.ubc.ca/spcoll/thesauth.html ABSTRACT Dioecy, the breeding system with male and female function on separate individuals, may affect the ability of a lineage to avoid extinction or speciate. Dioecy is a rare breeding system among the angiosperms (approximately 6% of all flowering plants) while hermaphroditism (having male and female function present within each flower) is predominant. Dioecious angiosperms may be rare because the transitions to dioecy have been recent or because dioecious angiosperms experience decreased diversification rates (speciation minus extinction) compared to plants with other breeding systems. -

“Behavior of Sarcocornia Fruticosa Under Salt Stress.”
Universidad de Almería Escuela Superior de Ingeniería Máster en Producción Vegetal en Cultivos Protegidos Trabajo Fin de Máster “Behavior of Sarcocornia fruticosa under salt stress.” “Tendencias de la distribución de nutrientes en Sarcocornia fruticosa bajo un gradiente salino” Autora: Maria Dolmatova Tutora: Mª Teresa Lao Arenas Behavior of Sarcocornia fruticosa under salt stress. Autora: María Dolmatova Tutora: Mª Teresa Lao Arenas Trabajo Fin de máster: diciembre 2012 1. Abstract Soil salinity, one of the major abiotic stresses reducing agricultural productivity, affects large terrestrial areas of the world; the need to produce salt-tolerant crops is evident. Most crops in agricultural production are sensitive to salt stress. Consequently, salinity is an ever-present threat to agriculture, especially in areas where secondary salinisation has developed through irrigation or deforestation. In turn, the research on salt-tolerant plants (known as halophytes plants) may provide the solution to this problem. Halophytes have evolved to grow in saline soils, developing a wide range of adaptations. In the present work we study the behavior of Sarcocornia fruticosa under salt stress. Two trials have carried out: Trial 1 with 2 saline treatments (3,51 and 58 mM NaCl) and trial 2 with three treatments (100 mM, 200 mM and 300 mM NaCl). The results indicate that S. fruticosa is capable of tolerating very high and continued exposure to salt, levels of 300 mM of NaCl presents similar biomass related 100 mM of NaCl. Neverhteless, the branches died increase significantly under high level of salinity. 2. Keywords: Salt, NaCl, native plant. 3. Introduction Almost three quarters of the surface of the earth is covered by salt water and so it is not surprising that salts affect a significant proportion of the world’s land surface (Flowers and Flowers, 2005). -

Rethinking Phylogenetics Using Caryophyllales (Angiosperms), Matk Gene and Trnk Intron As Experimental Platform
Rethinking phylogenetics using Caryophyllales (angiosperms), matK gene and trnK intron as experimental platform Sunny Sheliese Crawley Dissertation submitted to the faculty of the Virginia Polytechnic Institute and State University in partial fulfillment of the requirements for the degree of Doctor of Philosophy In Biological Sciences Khidir W. Hilu Eric P. Beers Carla V. Finkielstein Jill C. Sible December 2, 2011 Blacksburg, Virginia Keywords: (phylogeny, missing data, caryophyllids, trnK intron, matK, RNA editing, gnetophytes) Copyright 2011, Sunny Sheliese Crawley Rethinking phylogenetics using Caryophyllales (angiosperms), matK gene and trnK intron as experimental platform Sunny Sheliese Crawley ABSTRACT The recent call to reconstruct a detailed picture of the tree of life for all organisms has forever changed the field of molecular phylogenetics. Sequencing technology has improved to the point that scientists can now routinely sequence complete plastid/mitochondrial genomes and thus, vast amounts of data can be used to reconstruct phylogenies. These data are accumulating in DNA sequence repositories, such as GenBank, where everyone can benefit from the vast growth of information. The trend of generating genomic-region rich datasets has far outpaced the expasion of datasets by sampling a broader array of taxa. We show here that expanding a dataset both by increasing genomic regions and species sampled using GenBank data, despite the inherent missing DNA that comes with GenBank data, can provide a robust phylogeny for the plant order Caryophyllales (angiosperms). We also investigate the utility of trnK intron in phylogeny reconstruction at relativley deep evolutionary history (the caryophyllid order) by comparing it with rapidly evolving matK. We show that trnK intron is comparable to matK in terms of the proportion of variable sites, parsimony informative sites, the distribution of those sites among rate classes, and phylogenetic informativness across the history of the order. -

Pak. J. Bot., 48(6): 2307-2341, 2016. SEED MORPHOLOGY AND ITS TAXONOMIC SIGNIFICANCE IN THE FAMILY MALVACEAE RUBINA ABID*, AFSHEEN ATHER AND M. QAISER Department of Botany, University of Karachi, Karachi-75270, Pakistan *Corresponding author’s email: [email protected] Abstract The seed morphological studies of 75 taxa belonging to 6 sub-families of the family Malvaceae were carried out from Pakistan. In Pakistan the family Malvaceae is represented by 6 sub-families viz., Byttnerioideae, Dombeyoideae, Malvoideae, Bombacoideae, Helicteroideae and Sterculioideae. The seed macro and micro morphological characters are examined, using light (LM) and scanning electron microscopy (SEM). Detailed seed morphological descriptions, micrographs and keys based on seed characters are also provided. A variety in various quantitative and qualitative seed characters was observed. The micro-morphological characters of seeds are quite significant to strengthen the taxonomic decisions within the family Malvaceae at various levels. The data obtained from the seed morphological characters were analyzed numerically to trace out the phylogenetic affinities for the taxa within the family Malvaceae from Pakistan.

Research Paper Physicochemical
Academia Journal of Medicinal Plants 4(8): 001-009, July 2016 DOI: 10.15413/ajmp.2016.0108 ISSN: 2315-7720 ©2016 Academia Publishing Research Paper Physicochemical, Phytochemical and Nutritional values determination of Suaeda fruticosa (Chenopodiaceae) Accepted 20th May, 2016 ABSTRACT A medicinal plant is any plant which, in one or more of its organs, contains substances that can be used for therapeutic purposes or which are precursors for synthesis of useful drugs. Examples of important drugs obtained from plants are digoxin from dried leaves of Digitalis lanata (Family: Scrophulariaceae), quinine and quinidine from the bark of Cinchona species (Family: Rubiaceae). Physicochemical tests on powder and phytochemical tests for determination of secondary metabolites on Suaeda fruticosa dichloromethane extract (SFD) and methanolic extract (SFM) were done. High performance liquid chromatography (HPLC) was used for the quantitative determination of flavonoids using quercetin, myricetin and kaempferol as standards. Different elements were determined by atomic absorption spectrophotometer (AAS) to evaluate the nutritive value of S. fruticosa. Physicochemical tests showed that the values of moisture contents, total ash contents, water insoluble ash, acid insoluble ash, sulphated ash, water soluble extractives and alcohol soluble extractives in S. fruticosa were 2, 74, 34, 9, 20, 46 and 16% respectively. From phytochemical studies, it is estimated that tannins and flavonoids were present in both methanolic and dichloromethane extract of S. fruticosa while saponins and terpenoids were present in methanolic extract and alkaloids and coumarins present in dichloromethane extract. Quantitative determination of flavonoids showed that quercetin, myricetin and Kaempferol present in dichloromethane extract were 19.93, 0.15 and 0.15 mg/ml respectively and in methanolic extract, quercetin and kaempferol was present in quantity of 12.40 and 0.016 mg/ml Seema Abbas, Hammad Saleem, M.
