Flowering is a hot topic in Plant Biology and important progress has been made in Arabidopsis thaliana toward unravelling the genetic networks involved. The increasing complexity and the explosion of literature however require development of new tools for information management and update. We therefore created an evolutive and interactive database of flowering time genes, named FLOR-ID (Flowering-Interactive Database), that is available freely at http://www.flor-id.org. The hand-curated database contains information on 306 genes and links to 1595 publications gathering the work of more than 4500 authors. Gene function and interactions within the flowering pathways were inferred from the analysis of related publications, included in the database and translated into interactive manually drawn snapshots.

Phytostabilisation (i.e. using plants to immobilise contaminants) represents a well-known technology to hamper heavy metal spread across landscapes. In Katanga (D. R. Congo), Microchloa altera, a tolerant grass from the copper hills, was recently identified as a candidate species to stabilise copper in the soil. More than 50 grasses compose this flora, which may be studied to implement phytostabilisation strategies. However, little is known about their phenology, tolerance, reproductive strategy or demography. The present study aims to characterize the other Poaceae that may be used in phytostabilisation purposes based on the following criteria: their ecological distribution, seed production at two times, abundance, soil coverage and the germination percentage of their seeds. We selected seven perennial Poaceae that occur on the copper hills. Their ecological distributions (i.e. species response curves) have been modelled along copper or cobalt gradients with generalized additive models using logic link based on 172 presence/absence samples on three sites. For other variables, a total of 69 quadrats (1 m2) were randomly placed across three sites and habitats. For each species, we compared the number of inflorescence-bearing stems (IBS) by plot, the percentage of cover, the number of seeds by IBS and the estimated number of seeds by plot between sites and habitat. Three species (Andropogon schirensis, Eragrostis racemosa and Loudetia simplex) were very interesting for phytostabilisation programs. They produced a large quantity of seeds and had the highest percentage of cover. However, A. schirensis and L. simplex presented significant variations in the number of seeds and the percentage of cover according to site. [less ▲]

Science and technology require an intervention by the law, and law is called upon to intervene in front of their evolution, and to look for proper solutions of governance and rational responses to their risks. One of the main issues to be investigated from the legal viewpoint is represented by the ‘dual-use dilemma’ that arises both in ‘traditional’ and new areas of techno-sciences. Indeed, any kind of research has the potential to be used both for bad as well as for good purposes. Therefore, it is important to reflect upon the ways to control possibly dangerous research without preventing the progress from going further. Such ‘dual-use dilemma’, then, entails the study of one of the fundamental freedoms in the biolaw area: the freedom of scientific research, its limits, and relationship with other rights/needs/freedoms (such the need of security). This work focuses on two areas of the techno-scientific world. One is more ‘traditional’, i.e. nuclear science, in whose context the reflections on ‘dual-use’ were born and developed, and the other one is a new emerging technology, which is synthetic biology. The aim is to understand how the freedom of scientific research could be shaped in relationship with other rights/needs/interests for dealing with ‘dual-use’ issues in the aforementioned areas of science and technology.

This paper analyzes the articulation between mobility and technology within life trajectories marked by migration, exile and the search for economic achievement. It does so by focusing on a Nigerian couple’s (attempted) itinerary of return migration from Italy to Nigeria, and on the tensions that surround the role played by a specific transport technology, the shipping container, within this process. It highlights how, throughout the itinerary that brings the container from Italy to Nigeria, its social meaning and that of the cargo stored in it become the center of a series of tense interactions, in which diverging imaginaries about transnational mobility, migration and life abroad come to the fore, and provoke radical transformations in the life of the people involved in the itinerary of the container itself.

Depuis des siècles, les spécialistes et les savants des littératures grecque et latine se sont attachés à repérer les citations et les reprises d’un auteur chez un autre en raison de l’importance de l’imitatio et de l’aemulatio dans le processus de création littéraire des œuvres anciennes. Arrien de Nicomédie en est un parfait exemple puisqu’il s’inspira abondamment de son modèle admiré, Xénophon. C’est pourquoi, après avoir répertorié le plus grand nombre possible de réutilisations déjà mises au jour entre les deux historiens par les philologues de manière livresque, notre projet a pour but de détecter et de commenter de nouvelles réminiscences potentielles de Xénophon dans l’œuvre d’Arrien grâce à un logiciel développé spécifiquement à l’Université de Liège sur base de fichiers de textes lemmatisés en collaboration avec le LASLA.

This study provides detailed information, based on serial peels, on the anatomy of the primary and secondary xylem, lateral branch formation, and proposed growth pattern of Armoricaphyton Strullu-Derrien et al., an Early Devonian (Pragian) basal euphyllophyte. The centrarch primary xylem strand is circular to oval in cross section and includes P-type tracheids. The pattern of lateral branch departure is described in detail based on serial peels. The secondary xylem, illustrated in transverse, radial and tangential longitudinal sections, includes P-type tracheids with similar pitting in radial and tangential walls. The presence of one-walled spaces interpreted as rays is confirmed. This study also documents the earliest occurrence of secondary xylem at bases of next higher order of branches. A model of growth for this unusual Early Devonian plant is presented, with documented epidogenetic, menetogenetic and possible apoxogenetic phases. The difference in proportion of primary tosecondary xylem is postulated to be a result of this mode of growth. The possible implications of xylem size and organization in the lateral organ in Armoricaphyton relative to the early evolution of the megaphyllous leaf are briefly discussed. [less ▲]

In this study, a fully automatized in-capillary system was developed to monitor the activity of CYP1A1 in physiological conditions. Ethoxycoumarin, the selected substrate, undergoes an in-line bioreaction in the presence of CYP1A1 supersomes and NADPH as co-factor, giving rise to hydroxycoumarin, the product that was assayed. The optimization of the experimental conditions was supported by the application of a design of experiment, providing a better understanding of electrophoretic mixing parameters that influence the metabolic reactions. The results obtained in optimal conditions were compared not only to those achieved after off-line metabolization but also with liver microsomes. Finally, inhibition studies were conducted showing an important decrease of hydroxycoumarin formation using apigenin as CYP1A1 potent inhibitor. This study demonstrates the usefulness of our in-line system for the fully automated in vitro metabolism studies and the screening of new CYP1A1 inhibitors. [less ▲]

Ant mill, caterpillar circle, bat doughnut, amphibian vortex, duck swirl, and fish torus are different names for rotating circular animal formations, where individuals turn around a common center. These “collective vortex behaviors” occur at different group sizes from pairs to several million individuals and have been reported in a large number of organisms, from bacteria to vertebrates, including humans. However, to date, no comprehensive review and synthesis of the literature on vortex behaviors has been conducted. Here, we review the state of the art of the proximate and ultimate causes of vortex behaviors. The ubiquity of this behavioral phenomenon could suggest common causes or fundamental underlying principles across contexts. However, we find that a variety of proximate mechanisms give rise to vortex behaviors. We highlight the potential benefits of collective vortex behaviors to individuals involved in them. For example, in some species, vortices increase feeding efficiency and could give protection against predators. It has also been argued that vortices could improve collective decision making and information transfer. We highlight gaps in our understanding of these ubiquitous behavioral phenomena and discuss future directions for research in vortex studies. [less ▲]
