Pest categorisation of Satsuma dwarf virus
The EFSA Panelon Plant Health performed a pest categorisation of Satsuma dwarf virus (SDV) for the EU territory. SDV is a well-known pathogen and the type species of the genus Sadwavirus in the family Secoviridae. SDV is now considered to include several other formerly distinct viruses which are therefore also covered in the present opinion. Citrus species and their relatives represent the main hosts of SDV and efficient diagnostic techniques are available. SDV is listed on some of its known hosts in Annex IIAI of Directive 2000/29/EC. It is transmitted by vegetative propagation of infected hosts and presumably through the soil, but the precise mechanism or vector(s) are still unknown. SDV is present in Asia and is not known to occur in the EU. Therefore, it does not meet this criterion to qualify as a Union regulated non-quarantine pest (RNPQ). Plants for planting represent the main pathway for the entry, but this pathway is closed by existing legislation for the main hosts (Citrus, Fortunella and Poncirus). SDV is, however, able to enter the EU on plants for plants of its unregulated rutaceous or non-rutaceous hosts. Should it be introduced, SDV has the potential to establish and subsequently spread with plants for planting and, possibly, through its poorly characterised natural spread mechanism(s). SDV is able to cause severe symptoms, quality and yield losses on a range of citrus crops. Overall, SDV meets all the criteria evaluated by EFSA to qualify as a Union quarantine pest. The main knowledge gaps and uncertainties concern (1) the potential significance of the unregulated rutaceous and non-rutaceous hosts for virus dissemination and epidemiology, (2) the origin and trade volume of the plants for planting of these host imported in the EU and (3) theefficiency of natural spread of SDV under EU conditions
「いちかわ かぞえうた」プロジェクト活動報告(1)
近年、市川市は、高い人口流動率による地域への関心の薄さ等、首都近郊特有の地域課題を抱えている。そこで市川市内にある保育者養成課程を有する大学に在籍する筆者らは、令和2年(2020)度大学コンソーシアム市川産官学連携プラットフォーム協議会共同研究助成を受け、「いちかわ かぞえうた」プロジェクトを立ち上げた。本プロジェクトは、和洋女子大学と昭和学院短期大学の学生と教員が連携、協働し、市川で育つ子どもが地域に親しみ愛着が持てる遊び歌とそれに付随する「遊びバリエーション」の創作と普及活動を通じ、地域文化遺産の利活用と地域活性化に資する学生の教育、育成の2点を目的としている。 創作した遊び歌を、地域の子どもを通じて家庭や地域コミュニティーに広めることにより、「地域愛」を育むと共に、地域文化遺産の利活用を促す。また、市川で学ぶ学生が「いちかわ」を題材にした遊び歌とそれに付随する児童文化財や身体表現を創作し、保育所、幼稚園、認定こども園や地域で開催されるイベントでの実演を通じ地域の人と関わることで、地域活性化に資する人材の養成、育成を目指している。本稿は、これまでに創作した遊び歌とそれに付随する児童文化財、身体表現の制作、創作活動に焦点を当て報告する
Reactivity of polar organometallic compounds in unconventional reaction media : challenges and opportunities
Developing new green solvents in designing chemical products and processes or successfully employing the already existing ones is one of the key subjects in green chemistry and is especially important in organometallic chemistry, which is an interdisciplinary field. Can we advantageously also use unconventional reaction media in place of current harsh organic solvents for polar organometallic compounds? This microreview critically analyses the state of the art with regard to this topic and showcases recent developments and breakthroughs that are becoming new research directions in this field. Because metals cover a vast swath of the Periodic Table the content is organised into three sections discussing the reactivity of organometallic compounds of s-, p- and d-block elements in unconventional solvents
2021 Taxonomic update of phylum Negarnaviricota (Riboviria: Orthornavirae), including the large orders Bunyavirales and Mononegavirales.
Correction to: 2021 Taxonomic update of phylum Negarnaviricota (Riboviria: Orthornavirae), including the large orders Bunyavirales and Mononegavirales. Archives of Virology (2021) 166:3567–3579. https://doi.org/10.1007/s00705-021-05266-wIn March 2021, following the annual International Committee on Taxonomy of Viruses (ICTV) ratification vote on newly proposed taxa, the phylum Negarnaviricota was amended and emended. The phylum was expanded by four families (Aliusviridae, Crepuscuviridae, Myriaviridae, and Natareviridae), three subfamilies (Alpharhabdovirinae, Betarhabdovirinae, and Gammarhabdovirinae), 42 genera, and 200 species. Thirty-nine species were renamed and/or moved and seven species were abolished. This article presents the updated taxonomy of Negarnaviricota as now accepted by the ICTV.This work was supported in part through Laulima Government Solutions, LLC prime contract with the US National Institute of Allergy and Infectious Diseases (NIAID) under Contract No. HHSN272201800013C.
