Structural and functional genomics of symbiotic arbuscular mycorrhizal fungi.
2004
The absorbing organs (roots, rhizomes) of nearly all terrestrial plant families host an intimate symbiotic association, called a mycorrhiza, with specialized functional groups of soil fungi. The most common type of root symbiosis is the arbuscular mycorrhiza where soil fungi interact with a tremendous diversity of plant species, including many forest trees and agricultural, horticultural, and fruit crops (Gianinazzi et al., 2002). The fungi involved are very ancient microorganisms compared to other true fungi. Fossil data and molecular phylogenetic analyses indicate that their origin dates back to the Ordovician-Devonian era some 460 to 400 million years ago (Remy et al., 1994; Redecker et …
Molecular community and population studies of arbuscular mycorrhizal fungi (Glomeromycota)
2014
The arbuscular mycorrhizal symbiosis, which appeared at the same time as land plants, 460 million years ago, is a mutualistic beneficial association between most land plants, including those cultivated, and arbuscular mycorrhizal fungi (AMF). AMF, from the Glomeromycota phylum, are widespread soil microorganisms needing a photosynthetic host to complete their life cycle (obligate symbionts). The great potential of plant mineral nutrition improvement and crop production increased during this symbiosis, make AMF an asset in the context of an increase in the demand of world food crop production. The control of that symbiosis by ecology engineering in order to improve ecosystem services, especi…
Forward $J/\psi$ and very backward jet inclusive production at the LHC
2018
In the spirit of Mueller-Navelet dijet production, we propose and study the inclusive production of a forward $J/\psi$ and a very backward jet at the LHC as an observable to reveal high-energy resummation effects \`a la BFKL. We obtain several predictions, which are based on the various mechanisms discussed in the literature to describe the production of the $J/\psi$, namely, NRQCD singlet and octet contributions, and the color evaporation model.
High-energy evolution to three loops
2018
The Balitsky-Kovchegov equation describes the high-energy growth of gauge theory scattering amplitudes as well as nonlinear saturation effects which stop it. We obtain the three-loop corrections to this equation in planar $\mathcal{N}=4$ super Yang-Mills theory. Our method exploits a recently established equivalence with the physics of soft wide-angle radiation, so-called non-global logarithms, and thus yields at the same time the three-loop evolution equation for non-global logarithms. As a by-product of our analysis, we develop a Lorentz-covariant method to subtract infrared and collinear divergences in cross-section calculations in the planar limit. We compare our result in the linear re…
"That's Real! That's What You Want!": Producing Fear in George A. Romero's Dawn of the Dead (1978) vs Zack Snyder's remake (2004)
2011
International audience; This article examines traditional oppositions between terror and horror in Dawn of the Dead (1978) and its recent remake (2004), by focusing on one of the major changes made by the producers of the remake: the use of running zombies, which emphasizes the danger the creatures represent to the characters, and enables the film-makers to resort to the kind of cheap startle effects that abound in contemporary slasher and action movies. That the living dead of 1978 were slow-moving allowed for contemplation of their pathetic state and questioned the border between living and dead. The 1978 film underlined how incompatible the living dead were with such techniques that rely…
La genesi dei poemi omerici
2019
Si tratta della prima analisi sistematica di Iliade e Odissea scritta in una lingua diversa dal tedesco e del primo tentativo di dare un quadro generale delle analisi precedenti. Si cerca di distinguere i vari epe confluiti nei due poemi e come i Bearbeiter finali li hanno messi insieme. Le teorie panoraliste e unitarie vengono rifiutate, mentre vengono accettati i presupposti fondamentali dell’analisi, quale si è praticata per lo più da studiosi germanofoni nel sec. XIX e nella prima metà del XX.

Claustre Obert: Joan Romero, 'Federalisme,independentisme,centralisme,autonomisme: el cas català'
2013
'Federalisme, fronteres i fractures socials a Europa' és el títol de la conferència que imparteix Joan Romero hui dimecres 5 de juny. En un context en què les fronteres geogràfiques, culturals, estatals, científiques i urbanes es posen en qüestió, l' espai de debat Claustre Obert, de la Universitat de València i 'El País', analitza les claus d'aquest fenomen en dues conferències.
