Dissecting the factors controlling seed development in the model legume Medicago truncatula
2012
Legumes are not only indispensible for sustainable agriculture but are also a rich source of protein in food and feed for humans and animals, respectively. However, major proteins stored in legume seeds are poor in sulfur-containing amino acids, and may be accompanied by anti-nutritional factors causing low protein digestibility problems. In this regard, Medicago truncatula serves as a model legume to study legume seed development especially the phase of seed storage protein accumulation. As developing legume seeds are complex structures, a thorough knowledge of the morphogenesis of the seed and the characterization of regulatory mechanisms underlying the embryo development and seed filling…
Aspects fonctionnels, structuraux et évolutifs de la réponse transcriptionnelle à l’auxine
2017
Auxin is a plant hormone implicated in almost all plant developmental stages, since the embryo formation till flowering, determining the position of the organs in the plant and thus, its whole structure. As for any other hormone, auxin perception is followed by a signal transduction that finishes in a series of changes in a plant cell, including transcriptional changes. This thesis is divided in 3 chapters, each with a focus on the structural, molecular and evolutionary aspects of different proteins involved in the regulation of auxin genes response.First, we focused our studies on TOPLESS (TPL), a co-repressor implicated, not only in auxin responsive genes repression, but also in many othe…
