Biomarker metabolites are of increasing interest in crops since they open avenues for precision agriculture, whereby nutritional needs and stresses can be monitored optimally. Putrescine has the potential to be a useful biomarker to reveal potassium (K+) deficiency. In fact, although this diamine has also been observed to increase during other stre...
The latex collected from the Hevea brasiliensis tree is today the only commercial source of natural rubber (NR), the cis-1,4-polyisoprene polymer, a strategic raw material. The Hevea latex is a very complex material both in its structure and composition. In terms of structure, it is a colloidal dispersion where various micrometric objects, mainly r...
Plant traits—the morphological, anatomical, physiological, biochemical and phenological characteristics of plants—determine how plants respond to environmental factors, affect other trophic levels, and influence ecosystem properties and their benefits and detriments to people. Plant trait data thus represent the basis for a vast area of research sp...
La protéine chaperonne CDC48 (Cell division cycle 48) est un acteur important du contrôle qualité des protéines chez les eucaryotes et est associée à divers processus physio(patho)logiques chez les mammifères. En revanche, son rôle au sein du règne végétal a été peu appréhendé. Ce travail de thèse s’inscrit dans l’étude des fonctions de CDC48 chez ...
Skin aging is a complex biological process mixing intrinsic and extrinsic factors, such as sun exposure. At the molecular level, skin aging affects in particular the extracellular matrix proteins. Materials and Methods: Using Raman imaging, which is a nondestructive approach appropriate for studying biological samples, we analyzed how aging modifie...
UPF1 (Up-Frameshift 1) est une hélicase multifonctionnelle conservée chez tous les eucaryotes. Elle est essentielle à la voie de surveillance du NMD (Nonsense Mediated mRNA Decay), qui dégrade des ARNm portant un codon stop prématuré. UPF1 est l’archétype d’une famille d’hélicases qui partagent des corps similaires mais sont impliquées dans des voi...
Herbivorous insects cause important yield losses to crops. These insects are mainly managed through insecticides but negative effects of used compounds on the human health and the environment as well as the development of resistant pest populations impose finding alternative strategies to manage them. Breeding plants for enhanced resistance to inse...
This work brings together a wealth of data regarding the reference values and factors of variation in biochemical parameters used by camel veterinarians and scientists to determine these animals' nutritional and clinical status. It also explores several technical aspects involved in determining these parameters, sampling procedures, and essential e...
De nos jours, la souris est le modèle animal le plus largement utilisé en recherche et en particulier dans la recherche contre le cancer. Dans ce cadre, des modèles murins dits « humanisés » ont été développés. Il s'agit de souris immunodéficientes greffées avec des cellules ou tissus humains fonctionnels. La première partie de ce travail définit l...
