Amaranthus cruentus is a promising raw material for the biorefinery of whole plant. Stems are composed of (i) a bark on their periphery (76% w/w), and (ii) a pith in their middle (24% w/w), both usable for material applications. It is possible to separate mechanically and continuously these two fractions thanks to a fractionation process developed ...
Indoor air quality is a major public health issue. It is related to the choice of construction materials and associated with VOC emissions. Two wood-based commercial panels were tested: a medium-density fiberboard (MDF) and a chipboard (CH), and they were compared to a material produced from a coriander biorefinery (COR). Indicators chosen to compa...
Knowledge on sustainable grassland management is available in the large body of literature. However, it is unclear where to look for it, and what is really relevant to the many interrelated challenges of sustainable grassland management. This special issue illustrates options to fill some of those gaps. This editorial introduces the Special Issue e...
A key element in weed biological control is the selection of a biological control agent that minimizes the risks of non-target attack and indirect effects on the recipient community. Network ecology is a promising approach that could help decipher tritrophic interactions in both the native and the invaded ranges, to complement quarantine-based host...
The Rdr1 gene confers resistance to black spot in roses and belongs to a large TNL gene family, which is organized in two major clusters at the distal end of chromosome 1. We used the recently available chromosome scale assemblies for the R. chinensis ‘Old Blush’ genome, re-sequencing data for nine rose species and genome data for Fragaria, Rubus, ...
Seeds preserve a far developed plant embryo in a quiescent state. Seed metabolism relies on stored resources and is reactivated to drive germination when the external conditions are favorable. Since the switchover from quiescence to reactivation provides a remarkable case of a cell physiological transition we investigated the earliest events in ene...
Description du sujet. Cet article présente les productions de biomasses aériennes et souterraines de jeunes taillis à très courte rotation, non fertilisés, plantés sur des sols marginaux. Objectifs. Deux sols contrastés ont permis de suivre la croissance de saule, peuplier et robinier pour estimer leur production de biomasse exportable, l’immobilis...
In a context of increasing environmental challenges, there is an emerging demand for plant cultivars that are adapted to cultivation in species mixture. It is thus pressing to look for the optimization of selection schemes to grow species mixtures, and especially recurrent selection schemes which are at the core of the improvement of many plant spe...
Zucchini (Cucurbita pepo) is worldwide affected by Pseudomonas syringae inducing vein clearing, stunting and necroses during plantlet development. A collection of 58 P. syringae strains isolated from diseased zucchini plantlets was characterized by multilocus sequence analysis (MLSA). A subset of 23 strains responsible for vein clearing of zucchini...
