The transposable element-rich genome of the cereal pest Sitophilus oryzae

2021

AbstractBackgroundThe rice weevil Sitophilus oryzae is one of the most important agricultural pests, causing extensive damage to cereal in fields and to stored grains. S. oryzae has an intracellular symbiotic relationship (endosymbiosis) with the Gram-negative bacterium Sodalis pierantonius and is a valuable model to decipher host-symbiont molecular interactions.ResultsWe sequenced the Sitophilus oryzae genome using a combination of short and long reads to produce the best assembly for a Curculionidae species to date. We show that S. oryzae has undergone successive bursts of transposable element (TE) amplification, representing 72% of the genome. In addition, we show that many TE families a…

Chapter 12 Role of Iron in Plant–Microbe Interactions

2009

Iron is an essential micronutrient for plants and associated microorganisms. Iron nutrition of these organisms relies on the soil supply. However, bioavailability of iron in cultivated soils is low. Plants and microorganisms have thus evolved active strategies of iron uptake based on acidification, chelation, and/or reduction processes. Iron acquisition by these organisms leads to complex interactions ranging from mutualism to competition. In the rhizosphere, plants support abundant and active microbial communities through the release of rhizodeposits. Iron uptake by these microorganisms and by the host plant decrease even more the concentration of iron in solution. Therefore, there is an i…

Versatile and Dynamic Symbioses Between Insects and Burkholderia Bacteria

2020

Symbiotic associations with microorganisms represent major sources of ecological and evolutionary innovations in insects. Multiple insect taxa engage in symbioses with bacteria of the genus Burkholderia, a diverse group that is widespread across different environments and whose members can be mutualistic or pathogenic to plants, fungi, and animals. Burkholderia symbionts provide nutritional benefits and resistance against insecticides to stinkbugs, defend Lagria beetle eggs against pathogenic fungi, and may be involved in nitrogen metabolism in ants. In contrast to many other insect symbioses, the known associations with Burkholderia are characterized by environmental symbiont acquisition …

Valoisamman tulevaisuuden puolesta : YK:n yleiskokouksen täysistunnoissa sekä toisessa komiteassa käydyt keskustelut kestävästä kehityksestä vuonna 2…

2010

Kestävä kehitys oli ollut kansainvälisen yhteisön toiminnan päämääränä 1970-luvulta lähtien. Ilmiön taustalla oli kasvanut huoli ympäristön tilasta. Asiaan otettiin virallisesti kantaa ensimmäisen kerran Tukholman ympäristökonferenssissa vuonna 1972, jonka jälkeen vuonna 1987 kestävä kehitys konkretisoitui käsitteenä niin sanotun Bruntlandin komission raportissa seuraavalla tavalla: "Kestävä kehitys on kehitystä, joka tyydyttää nykyhetken tarpeet viemättä tulevilta sukupolvilta mahdollisuutta tyydyttää omat tarpeensa". Käsitteestä tuli tämän jälkeen suosittu kansainvälisen yhteisön keskuudessa. Kestävän kehityksen edistämisen yhtenä pääarkkitehtina voidaan pitää YK:ta, joka järjesti monia k…

Do young graduates with professional and vocational master's degrees regard themselves as competent to hold their jobs ?

2016

En ligne sur http://www.cereq.fr/content/download/16090/129720/file/Trai118.pdf; Professional and vocational courses requiring 5 years' post-secondary study are supposed to meet specific needs for competences in a given area of employment. Young graduates believe they have acquired the specific competences they think their employers require. In their view, the shortfall lies in their general competences. Is this a reason to question the increasingly vocational nature of university courses?

Creativity and Innovation in Technology-Mediated Journalistic Work : Mapping out Enablers and Constraints

2020

This qualitative study examines creativity and innovation in dispersed, journalistic teams. Specifically, we study the factors enabling and constraining creativity and innovation in journalistic work in technology-mediated settings and explore how technology shapes these phenomena in dispersed journalistic teams. The study is motivated by the media industry’s heightened need for creativity and innovation as well as the changing nature of working life where an increasing amount of work is done via information and communication technologies. By closely examining two journalistic teams and their idea sharing and development processes, this study finds that successful creative work and innovati…

Kawasaki disease epidemic: pitfalls

2020

AbstractRecent reports have described in the pediatric population a new type of hyperinflammatory response manifested following contact with SARS-CoV-2, with some of the clinical features attributable to Kawasaki disease (KD). The purpose of this commentary is to remark on a possible recent association between SARS-CoV-2 and KD. Although today little is known about the etiology of KD, the most accepted hypothesis is that of a probable viral etiology, therefore, even the SARS-CoV-2 virus could trigger, in genetically predisposed subjects, an exaggerated inflammatory response that is clinically evident like the one described in KD.

Unrealistic Optimism in the Time of Coronavirus Pandemic: May It Help to Kill, If So—Whom: Disease or the Person?

2020

Objective: The results of numerous empirical studies have showed the occurrence of so-called unrealistic optimism. Thus, we aimed to investigate whether in the situation of an imminent coronavirus pandemic, people would still perceive themselves as being less exposed to the disease than others. Methods: Survey studies were conducted to examine the level of unrealistic optimism. Participants (n = 171, 67.3% of women) in a subjective way judged the risk of their coronavirus infection and the likelihood that this would happen to an average student of the same sex from their class. The survey was conducted in three waves: prior to the announcement of the first case of coronavirus (2&ndash

Mapping the Idea of Europe : Cultural Production of Border Imaginaries through Heritage

2021

In contrast to recent reinforcements of Europe's internal and external borders due to the refugee situation on the Mediterranean and the Covid-19 outbreak, talk of European borders has in the past decades focused on the freedom of mobility guaranteed by the Schengen treaty. In many senses, free intra-European mobility has become a recited truth in the EU discourse: a phrase that hides under its repetition the gap between its implied content and empirical realities of many of those who are affected by European borders’ exclusive tendencies. Through the concept of borderscape, this article focuses on the role that cultural products – especially maps exhibited at heritage sites – have in recit…
