Vietnam’s conifer flora has approximately 34 species that are indigenous to the country, making up about 5% of conifers known worldwide. Although conifers represent only less than 0.3% of the total number of higher vascular plant species of Vietnam, they are of great ecological, cultural and economic importance. Most conifer wood is prized for its high value in house construction, furniture making, etc. The decline of conifer populations in Vietnam has caused serious concern among scientists. Threats to conifer species are substantial and varied, ranging from logging (both commercial and subsistence), land clearing for agriculture, and forest fire. Over the past twelve years (1995-2006), Vietnam Botanical Conservation Program (VBCP), a scientific cooperation between the Missouri Botanical Garden in Saint Louis and the Institute of Ecology and Biological Resources in Hanoi, has conducted various studies on this important group of plants in order to gather baseline information necessary to make sound recommendations for their conservation and sustainable use.

Bunzo Hayata and His Contributions to the Flora of Taiwan
TAIWANIA, 54(1): 1-27, 2009 INVITED PAPER Bunzo Hayata and His Contributions to the Flora of Taiwan Hiroyoshi Ohashi Botanical Garden, Tohoku University, Sendai 980-0962, Japan. Email: [email protected] (Manuscript received 10 September 2008; accepted 24 October 2008) ABSTRACT: Bunzo Hayata was the founding father of the study of the flora of Taiwan. From 1900 to 1921 Taiwan’s flora was the focus of his attention. During that time he named about 1600 new taxa of vascular plants from Taiwan. Three topics are presented in this paper: a biography of Bunzo Hayata; Hayata’s contributions to the flora of Taiwan; and the current status of Hayata’s new taxa. The second item includes five subitems: i) floristic studies of Taiwan before Hayata, ii) the first 10 years of Hayata’s study of the flora of Taiwan, iii) Taiwania, iv) the second 10 years, and v) Hayata’s works after the flora of Taiwan. The third item is the first step of the evaluation of Hayata’s contribution to the flora of Taiwan. New taxa in Icones Plantarum Formosanarum vol. 10 and the gymnosperms described by Hayata from Taiwan are exampled in this paper. KEY WORDS: biography, Cupressaceae, flora of Taiwan, gymnosperms, Hayata Bunzo, Icones Plantarum Formosanarum, Taiwania, Taxodiaceae. 1944). Wu (1997) wrote a biography of Hayata in INTRODUCTION Chinese as a botanist who worked in Taiwan during the period of Japanese occupation based biographies and Bunzo Hayata (早田文藏) [1874-1934] (Fig. 1) was memoirs written in Japanese. Although there are many a Japanese botanist who described numerous new taxa in articles on the works of Hayata in Japanese, many of nearly every family of vascular plants of Taiwan.

TAXODIACEAE.Publishe
Flora of China 4: 54–61. 1999. 1 TAXODIACEAE 杉科 shan ke Fu Liguo (傅立国 Fu Li-kuo)1, Yu Yongfu (于永福)2; Robert R. Mill3 Trees evergreen, semievergreen, or deciduous, monoecious; trunk straight; main branches ± whorled. Leaves spirally arranged or scattered (decussate in Metasequoia), monomorphic, dimorphic, or trimorphic on same tree, lanceolate, subulate, scalelike, or linear. Microsporophylls and cone scales spirally arranged (decussate in Metasequoia). Pollen cones borne in panicles, or solitary or clustered at branch apices, or axillary, small; microsporangia with (2 or)3 or 4(–9) pollen sacs; pollen nonsaccate. Seed cones terminal or borne near apex of previous year’s growth, ripening in 1st year, persistent or late deciduous; cone scales developing after ovules originate in bract axils; bracts and cone scales usually spirally aranged (decussate in Metasequoia), sessile, opening when ripe (falling in Taxodium), semiconnate and free only at apex, or completely united; bracts occasionally rudimentary (in Taiwania); ovules 2–9 per bract axil, erect or pendulous; cone scales of mature cones flattened or shield-shaped, woody or leathery, 2–9-seeded on abaxial side. Seeds flat or triangular, wingless (in Taxodium), narrowly winged all round or on 2 sides, or with a long wing on proximal part. Cotyledons 2–9. 2n = 22*. Nine genera and 12 species: Asia, North America, and (Athrotaxis D. Don) Tasmania; eight genera (one endemic, three introduced) and nine species (one endemic, four introduced) in China. A merger of the Taxodiaceae and Cupressaceae is increasingly supported by both morphological and molecular evidence (see note under Cupressaceae). However, the two groups are kept as separate families here for pragmatic reasons.

Silva Received: 16 July 2019; Accepted: 29 July 2019; Published: 21 August 2019 Abstract: The resins bled from stems and in seed cones and leaves of Cryptomeria japonica, Glyptostrobus pensilis, Taxodium distichum, and T. mucronatum were characterized to provide an overview of their major natural product compositions. The total solvent extract solutions were analyzed as the free and derivatized products by gas chromatography-mass spectrometry to identify the compounds, which comprised minor mono- and sesquiterpenoids, and dominant di- and triterpenoids, plus aliphatic lipids (e.g., n-nonacosan-10-ol). Ferruginol, 7α-p- cymenylferruginol, and chamaecydin were the major characteristic markers for the Taxodioideae conifer subfamily. The mass spectrometric data can aid polar compound elucidation in environmental, geological, archeological, forensic and pharmaceutical studies.

Expression and Function of the Chloroplast-Encoded Gene Matk
Expression and Function of the Chloroplast-encoded Gene matK. Michelle Marie Barthet 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 K. W. Hilu, Chair E. Beers G. Gillaspy J. Sible R. A. Walker February 9, 2006 Blacksburg, Virginia Keywords: MatK, chloroplast, maturase, fast-evolving, Orchidaceae Copyright 2006, Michelle Marie Barthet Expression and Function of the chloroplast-encoded gene matK. Michelle Marie Barthet ABSTRACT The chloroplast matK gene has been identified as a rapidly evolving gene at nucleotide and corresponding amino acid levels. The high number of nucleotide substitutions and length mutations in matK has provided a strong phylogenetic signal for resolving plant phylogenies at various taxonomic levels. However, these same features have raised questions as to whether matK produces a functional protein product. matK is the only proposed chloroplast-encoded group II intron maturase. There are 15 genes in the chloroplast that would require a maturase for RNA splicing. Six of these genes have introns that are not excised by a nuclear imported maturase, leaving MatK as the only candidate for processing introns in these genes. Very little research has been conducted concerning the expression and function of this important gene and its protein product. It has become crucial to understand matK expression in light of its significance in RNA processing and plant systematics. In this study, we examined the expression, function and evolution of MatK using a combination of molecular and genetic methods. Our findings indicate that matK RNA and protein is expressed in a variety of plant species, and expression of MatK protein is regulated by development.

Guidance Notes for Application for Registering a Cultivar of Conifer
APPLICATION FORM FOR REGISTERING A CONIFER CULTIVAR NAME NOTES FOR GUIDANCE IN COMPLETING THE FORM NORTH AMERICAN APPLICATIONS ONLY Introduction The Royal Horticultural Society was appointed International Cultivar Registration Authority (ICRA) for Conifers by the International Society for Horticultural Science (ISHS) in 1962. The ICRA system aims to promote stability within the naming of cultivated plants by promoting lists of authenticated names in a number of important groups of plants which are commonly cultivated. The Registration Form is designed to bring together all the information that the ICRA requires so that the Registrar may ensure that a new cultivar name is properly established within the rules as laid down in the International Code of Nomenclature for Cultivated Plants (ICNCP). This Code is issued at periodic intervals under the authority of the International Commission for the Nomenclature of Cultivated Plants, a body which itself lies under the aegis of the International Union of Biological Sciences (IUBS). The Code is available in North America from Balogh Scientific Books, 1911 North Duncan Road, Champaign, Illinois 61821, USA (http://www.balogh.com). E-mail: [email protected], Fax: (217) 355-9413, Telephone: (217) 355-9331 or 355-1704. The term “Conifer” has a number of meanings in different parts of the world, but for the purposes of registration, the following genera are considered to be Conifers under the ICRA scheme: Abies Mill., Acmopyle Pilg., Actinostrobus Miq., Afrocarpus (J. Buchholz & N. E. Gray) C. N. Page, Agathis Salisb., Amentotaxus Pilg., Araucaria Juss., Athrotaxis D. Don, Austrocedrus Florin & Boutelje, Austrotaxus R. H.
