MEANING OF PHARMACOGNOSY Pharmacognosy, known initially as materia medica, may be defined as the study of crude drugs obtained from plants, animals and mineral kingdom and their constituents. There is a historical misinformation about who created the term pharmacognosy. According to some sources, it was C. A. Seydler, a medical student at Halle, Germany, in 1815; he wrote his doctoral thesis titled Analectica Pharmacognostica. However, recent historical research has found an earlier usage of this term. The physician J. A. Schmidt (Vienna) used that one in his Lehrbuch der materia medica in 1811, to describe the study of medicinal plants and their properties. The word pharmacognosy is derived from two Latin words pharmakon, ‘a drug,’ and gignoso, ‘to acquire knowledge of’. It means ‘knowledge or science of drugs. Crude drugs are plants or animals, or their parts which after collection are subjected only to drying or making them into transverse or longitudinal slices or peeling them in some cases. Most of the crude drugs used in medicine are obtained from plants, and only a small number comes from animal and mineral kingdoms. -

Prof. D.A. Agboola: BOT221: Seedless Plants/Cryptogamic Botany CRYPTOGAMS - Flowerless or seedless plants - Lower and more primitive plants - 3 main groups i.e. Thallophyte, Bryophyte and Pteridophyte - Thallophytes include: Algae, fungi, Bacteria and lichens - Bryophytes include liverworts, horned liverworts and mosses - Pteridophytes include ferns and their allies. Reproduction - Members may take one or more of 3 methods of reproduction including vegetative, asexual and sexual - Vegetative by cell division or fragmentation - Asexual is through production of various types of spores - Sexual takes place by fusion of two gametes - Degree of sexuality passes through progressive stages including isogamy, anisogany to oogamy - Isogamy takes place in primitive cryptogams where two gametes of similar shape, size and behavior (isogametes) occurs - In anisogamy the two gametes, may be slightly different in size and behavior (Anisogametes) - In advanced cryptogams the two gametes become differentiated into male i.e. microgametes or antherozoids as spermatozoa and the female i.e. megagametes, the egg cell or oosphere or ovum - The egg cell is housed in structures including oogonium - The antherozoids are housed in antheridium - In oogamous cryptogams, the male gamete is usually small, ciliated or flagellated, active and initiative - The egg cell in large, non-motile, non ciliated, passive and receptive - Alternation of generation occurs in higher algae, liverworts, mosses, ferns and related pteridophyte - Here, life history is completed in two alternative stages or generations - These two generations differ in both morphological characteristics and mode of reproduction - One generation i.e. the sporophytic generation or asexual generation reproduces asexually by means of spores - While the other generation, i.e. -
Principles of Plant Taxonomy. Ix.*
PRINCIPLES OF PLANT TAXONOMY. IX.* JOHN H. SCHAFFNER. In the eighth paperf of the present series, a general synopsis of the Thallophyta was given, together with a diagramatic "tree" of relationships of the orders recognized. Since the fungi are of special importance and are thus often studied independently of other groups and since the true fungi evolved a distinctive type of plant body and cell constitution, the following analysis is presented as a partial explanation of the arrangement of the groups in the synopsis. Special attention has been given to the development of correct interpretations of life histories in the light of special studies on the problem of sex in plants in general as well as comparative studies of life cycles. THE FOUR GENERAL TYPES OF FUNGI. If we use the term Fungi to include all Thallophytes without chlorophyll, then these plants fall into at least four distinctive, fundamental groups or great phyla. The various kinds of bacteria, including the slime bacteria (Myxobacteriales), show a very profound segregation from the remaining groups and are closely associated with the blue-green algae in the Schizophyta. The saprophytic slime-molds constitute a very 'distinct phylum of their own, whose nearest relatives are probably to be found among the Rhizopoda of the animal kingdom on the one hand and among the Archemycetae on the other, especially the Plasmodiophorales. But they are, nevertheless, so widely divergent from either of these groups that they are best con- sidered as a distinct phylum which has evolved along its own lines from a very primitive starting point. -

Symbiomonas scintillans Guillou et Chrétiennot-Dinet gen. et sp. nov. was isolated from samples collected both in the equatorial Pacific Ocean and the Mediterranean Sea. This new species possesses ultrastructural features of the bicosoecids, such as the absence of a helix in the flagellar transitional region (found in Cafeteria roenbergensis and in a few bicosoecids), and a flagellar root system very similar to that of C. roenbergensis, Acronema sippewissettensis, and Bicosoeca maris. This new species is characterized by a single flagellum with mastigonemes, the presence of en- dosymbiotic bacteria located close to the nucleus, the absence of a lorica and a R3 root composed of a 6+3+x microtubular structure. Phylogenetical analyses of nuclear-encoded SSU rDNA gene se- quences indicate that this species is close to the bicosoecids C. -

Accepted: February 8, 2016 Data deposition: The newly determined mitogenome sequences were deposited at GenBank with accession numbers KU501220–KU501222. Individual gene or cDNA sequences extracted from unpublished nuclear genome or transcriptome assemblies were deposited at GenBank with accession numbers KU501223–KU501236. Abstract Eustigmatophyceae (Ochrophyta, Stramenopiles) is a small algal group with species of the genus Nannochloropsis being its best studied representatives. Nuclear and organellar genomes have been recently sequenced for several Nannochloropsis spp., but phylogenetically wider genomic studies are missing for eustigmatophytes. We sequenced mitochondrial genomes (mitogenomes) of three species representing most major eustigmatophyte lineages, Monodopsis sp. MarTras21, Vischeria sp. CAUP Q 202 and Trachydiscus minutus, and carried out their comparative analysis in the context of available data from Nannochloropsis and other stramenopiles, revealing a number of noticeable findings. First, mitogenomes of most eustigmatophytes are highly collinear and similar in the gene content, but extensive rearrangements and loss of three otherwise ubiquitous genes happened in the Vischeria lineage; this correlates with an accelerated evolution of mitochondrial gene sequences in this lineage. Second, eustigmatophytes appear to be the only ochrophyte group with the Atp1 protein encoded by the mitogenome. -

EDRS PRICE MF-$0.75 HC-$3.15 PLUS POSTAGE DESCRIPTORS *Biology; Curriculum Design; *Curriculam Guides; *Human Development; *Junior High School Students; Science Education; Secondary School Science IDENTIFIERS South Carolina ABSTRACT This curricular guide focuses on life science and is designed for use with seventh grade students. Life science was chosen as the course of study based on the rationale that, as pupils enter junior high school, they are in early adolescence and .find it difficult to understand themselves so that the study of living things with a thorough explanation of the functions of the human body and its behavior seems appropriate. The guide contains objectives (not stated in behavioral form), a content outline, types of suggested activities, materials required, points to consider when evaluating the attainment of the objectives, a 362-word vocabulary list (arranged in alphabetical order), a bibliography for students and for teachers, and a list of filmstrips available in the prsofessiopal library of the school district (Rock Hill, South Carolina) for which this guide was developed.

J Mol Evol (2006) 62:388–420 DOI: 10.1007/s00239-004-0353-8 Phylogeny and Megasystematics of Phagotrophic Heterokonts (Kingdom Chromista) Thomas Cavalier-Smith, Ema E-Y. Chao Department of Zoology, University of Oxford, South Parks Road, Oxford OX1 3PS, UK Received: 11 December 2004 / Accepted: 21 September 2005 [Reviewing Editor: Patrick J. Keeling] Abstract. Heterokonts are evolutionarily important gyristea cl. nov. of Ochrophyta as once thought. The as the most nutritionally diverse eukaryote supergroup zooflagellate class Bicoecea (perhaps the ancestral and the most species-rich branch of the eukaryotic phenotype of Bigyra) is unexpectedly diverse and a kingdom Chromista. Ancestrally photosynthetic/ major focus of our study. We describe four new bicil- phagotrophic algae (mixotrophs), they include several iate bicoecean genera and five new species: Nerada ecologically important purely heterotrophic lineages, mexicana, Labromonas fenchelii (=Pseudobodo all grossly understudied phylogenetically and of tremulans sensu Fenchel), Boroka karpovii (=P. uncertain relationships. We sequenced 18S rRNA tremulans sensu Karpov), Anoeca atlantica and Cafe- genes from 14 phagotrophic non-photosynthetic het- teria mylnikovii; several cultures were previously mis- erokonts and a probable Ochromonas, performed ph- identified as Pseudobodo tremulans. Nerada and the ylogenetic analysis of 210–430 Heterokonta, and uniciliate Paramonas are related to Siluania and revised higher classification of Heterokonta and its Adriamonas; this clade (Pseudodendromonadales three phyla: the predominantly photosynthetic Och- emend.) is probably sister to Bicosoeca. Genetically rophyta; the non-photosynthetic Pseudofungi; and diverse Caecitellus is probably related to Anoeca, Bigyra (now comprising subphyla Opalozoa, Bicoecia, Symbiomonas and Cafeteria (collectively Anoecales Sagenista). The deepest heterokont divergence is emend.). Boroka is sister to Pseudodendromonadales/ apparently between Bigyra, as revised here, and Och- Bicoecales/Anoecales.
