Abstract:

Wood formation is heavily exploited for the manufacturing of pulp, paper, sustainable biomaterials and, potentially, biofuels. Eucalyptus is a favourable fast-growing, short rotation plantation crop grown over millions of hectares globally for its superior fiber properties. Understanding the molecular biology of secondary cell wall (SCW) formation in trees, and in particular how it is transcriptionally and epigenetically regulated, lays the foundation for enhanced woody trait improvement strategies in tree biotechnology. Transcriptional networks regulating SCW biosynthesis have been discovered

Abstract:

Wood has a wide variety of uses and is arguably the most important renewable raw material. The composition of xylem cell types in wood determines the utility of different types of wood for distinct commercial applications. Using expression profiling and phylogenetic analysis, we identified many xylem-associated regulatory genes that may control the differentiation of cells involved in wood formation in Arabidopsis and poplar. Prominent among these are NAC-domain transcription factors (NACs). In addition to their roles as regulators of xylem differentiation, NACs are regulators of meristem dev

Abstract:

THESIS OUTLINE In the present thesis work, the senescence process in fruit and leaf has been investigated through the analysis of different mutant lines of Arabidopsis thaliana and Solanum lycopersicum. In particular, the work has focused on the downregulation of three NAC transcription factor genes, NAC058 (AT3G18400), NAC100 (AT5G61430, both analysed in Arabidopsis), and HEBE (Solyc12g036480), analysed in tomato. All of them have been selected for the analysis due to their putative role in senescence, e.g. their expression has been detected in senescing siliques (NAC058, NAC100) and in ripe

Abstract:

Myogenesis is a complex and tightly regulated process, the end result of which is the formation of multinucleated myofibers. Muscle formation requires the precise expression of multiple myogenic regulatory factors (MRFs), whose expression regulates transcription of muscle specific proteins. Alteration in the expression of a muscle specific gene or protein ultimately results in muscle dysfunction. The inappropriate expression of factors that control muscle development may also be a contributing factor in Rhabdomyosarcoma, a pediatric cancer that accounts for most soft tissue sarcomas that aris

Abstract:

Wheat is the most important grain crop grown in our country providing greatest part of the daily nutritional requirement. Abiotic factors including salinity, drought, cold and heat stresses affect quality and yield of wheat varieties used for the production of both bread and pasta flour. NAC proteins form one of the widest families of plant specific transcription factors. Members of this family are related with development, defense and abiotic stress responses. TaNAC69-1 and TtNAM-B2 genes were isolated from T.aestivum and T.turgidum, respectively. Then they were cloned into different monoco

Le blé tendre, Triticum aestivum, est une des céréales les plus cultivées dans le monde. Le changement climatique qui se développe actuellement contraint fortement les cultures et altère leur rendement. La compréhension des mécanismes de réponse du blé tendre aux stress abiotiques est donc une problématique d’actualité. Plusieurs grandes familles de facteurs de transcription, dont la famille NAC,interviennent dans le développement de la plante et dans sa réponse aux stress environnementaux. Cette thèse, structurée en 3 volets, est ciblée sur l’étude de la famille NAC chez le blé tendre : les T

Abstract:

The NAM-B1 transcription factor increases grain protein content, alters grain micronutrient content and accelerates monocarpic senescence, often without imposing a yield penalty. The aim of this thesis was to understand the mechanisms by which NAM-B1 influences nutrient remobilisation and monocarpic senescence to cause these effects. To achieve this I have examined the expression patterns of NAM-B1 and its homologues during development. I have studied the effects of NAM-B1 on nutrient transport, photosynthetic capacity and grain filling using a range of molecular biology and physiological tech

Abstract:

Soil salinity and heat stress are two major abiotic stresses affecting plant growth and yield. Transcription factors (TFs) are key regulators in stress responses. They link stress sensing with many tolerance mechanisms by translating stress signals into changes in gene expression that ultimately contribute to stress tolerance. The NAC (NAM, ATAF and CUC) TF family have been found to be involved in responses to biotic and abiotic stresses. In this PhD project, the role of NAC TFs in response to heat and salt stress was studied in the model system Arabidopsis thaliana (Arabidopsis), and in two a
