    The 'Plantain-Optim' dataset (came from the 'Plantain-Optim' experiment conducted from 2009 to 2011 at CARBAP experimental station in Cameroon. The main objective was to describe agronomic potential of nine plantain varieties, including five natural plantains commonly cropped in Cameroon, and four plantain-like hybrids. A completely randomized bloc permitted to compare growth, development and yield of 45 plants per variety split between five replicates. Cropping practices guarantied non-limiting and homogenous conditions. Each plant was measured every 15 days. Data described aerial organ sizes, foliar structure and bunch characteristics of the mother plant. The 'Plantain-Optim' dataset includes the complete individual growth of each studied plantain of the 'Plantain-Optim' experiment with a 15-day accuracy. It is a useful standard of plantain varietal diversity for comparison with others datasets. Varietal growth and development homogeneity, biomass production or foliar and bunch structures could be further investigated. Moreover, these accurate data on plantain growth could be valuable for plantain 3D modelling

    <p>Abstract</p> <p>Background</p> <p>The ubiquitin protein is present in all eukaryotic cells and promoters from ubiquitin genes are good candidates to regulate the constitutive expression of transgenes in plants. Therefore, two switchgrass (<it>Panicum virgatum </it>L.) ubiquitin genes (<it>PvUbi1 </it>and <it>PvUbi2</it>) were cloned and characterized. Reporter constructs were produced containing the isolated 5' upstream regulatory regions of the coding sequences (i.e. <it>PvUbi1 </it>and <it>PvUbi2 </it>promoters) fused to the <it>uidA </it>coding region (<it>GUS</it>) and tested for transient and stable expression in a variety of plant species and tissues.</p> <p>Results</p> <p><it>PvUbi1 </it>consists of 607 bp containing <it>cis</it>-acting regulatory elements, a 5' untranslated region (UTR) containing a 93 bp non-coding exon and a 1291 bp intron, and a 918 bp open reading frame (ORF) that encodes four tandem, head -to-tail ubiquitin monomer repeats followed by a 191 bp 3' UTR. <it>PvUbi2 </it>consists of 692 bp containing <it>cis</it>-acting regulatory elements, a 5' UTR containing a 97 bp non-coding exon and a 1072 bp intron, a 1146 bp ORF that encodes five tandem ubiquitin monomer repeats and a 183 bp 3' UTR. <it>PvUbi1 </it>and <it>PvUbi2 </it>were expressed in all examined switchgrass tissues as measured by qRT-PCR. Using biolistic bombardment, <it>PvUbi1 </it>and <it>PvUbi2 </it>promoters showed strong expression in switchgrass and rice callus, equaling or surpassing the expression levels of the CaMV <it>35S, 2x35S, ZmUbi1</it>, and <it>OsAct1 </it>promoters. GUS staining following stable transformation in rice demonstrated that the <it>PvUbi1 </it>and <it>PvUbi2 </it>promoters drove expression in all examined tissues. When stably transformed into tobacco (<it>Nicotiana tabacum</it>), the <it>PvUbi2+3 </it>and <it>PvUbi2+9 </it>promoter fusion variants showed expression in vascular and reproductive tissues.</p> <p>Conclusions</p> <p>The <it>PvUbi1 </it>and <it>PvUbi2 </it>promoters drive expression in switchgrass, rice and tobacco and are strong constitutive promoter candidates that will be useful in genetic transformation of monocots and dicots.</p

    Les mises en scène de la guerre au XXe siècle : Théâtre et cinéma

    No full text
    International audienceSi le XXe siècle a été celui des guerres, il a été aussi celui de l'avènement de la mise en scène de théâtre et de cinéma. Cet ouvrage interroge le lien étroit et vivant entre guerre et mise en scène, tant théâtrale que cinématographique. Car le phénomène de la guerre, à travers lequel s'écrit l'histoire du siècle, n'en finit pas de questionner la représentation artistique, et de renvoyer le théâtre et le cinéma à leurs propres limites, éthiques et esthétiques, les invitant à dépasser celles-ci pour s'inventer des formes nouvelles. Abordant les représentations de cinq périodes ou conflits charnières, la Première et la Seconde Guerre mondiale, les guerres postcoloniales, les guerres du Proche-Orient, le conflit en ex-Yougoslavie et l'après-11-Septembre, les études rassemblées ici sont l’œuvre d'universitaires, de spécialistes, et ménagent une parole aux artistes eux-mêmes (cinéastes, metteurs en scène, auteurs, traducteurs). Elles abordent le traitement fictionnel aussi bien que la démarche documentaire, en faisant la part de leurs interpénétrations. Se dessinent de la sorte un panorama des événements les plus tragiques et destructeurs de notre histoire contemporaine, mais aussi un parcours des œuvres qui, depuis cent ans jusqu'à notre plus récente actualité, se sont acharnées à construire une mémoire vivante de notre passé et de notre présent
