Puzzling out the role of plant and fungal laccases with auxiliary enzymes during polymerization and depolymerization of lignin in a polysaccharide environment – DEOX
polysaccharide matrix of the plant cell wall. The lignin deposition makes the plant biomass highly recalcitrant [...] hydroxycinnamic acid-grafted plant cell walls. During this project, an innovative plant material will be produced: [...] differences between fungal and plant laccases, high yield production of plant laccases in heterologous expression
DELLA-mediated regulation of plant growth and oxidative stress tolerance: A role for ROS? – DELLAROS
Unlike animals, plants cannot escape adverse environments just by moving away. Plants live in fixed locations [...] delays plant life-cycle and decreases yields. Therefore, understanding mechanisms regulating plant growth [...] controlling plant form. The proposed research aims to determine whether GA-mediated plant growth and stress
Plant manganese nutrition for optimal photosynthesis and growth – PlantMan
The project aims at understanding the mechanisms that enable plant to capture manganese, an essential nutrient, from soils and bring it to the photosynthetic centers where it plays a critical role in producing dioxygen from water and convert solar energy to chemical energy for the cell.
Manganese uptake in Arabidopsis : genomic analysis and regultory networks – MANOMICS
Manganese (Mn) is an essential micronutrient in plants and hence limits their growth in the large areas of soil where it is scarce. Understanding the molecular mechanisms that underlie and control Mn acquisition is a prerequisite to develop plants that are better adapted to Mn deficiency.
Role of extracellular vesicles in plant-microbe interactions – Exosomes
Exosomes are small extracellular vesicles (EVs) secreted from cells by the fusion of multivesicular bodies (endosomes) with the plasma membrane. Although they are implicated in intercellular transport of sRNAs and proteins in animals and plants, very little is known about EV composition or functions in filamentous fungi.
Identification of key Molecular switches for the Adaptation to Nitrogen Availability in plants – IMANA
Despite the in-depth knowledge on N metabolism, only recently molecular players involved in these regulatory circuits have been discovered. A previous collaboration between two partners of this proposal revealed the key role of the transcription factor NLP7 in early nitrate signalling.
Regulation of glycerolipids interconversion in plants in response to environmental variations – Reglisse
Lipidome modifications are tightly associated with various additional traits promoted by Pi deficiency. It is<br />therefore difficult to evaluate the real impact of lipidome modifications on plant physiology. This proposal<br />thus circumvents such limitation by using various genetic tools (mutants or drugs identified by a chemical<br />genetic strategy deployed by partners of this proposal) to uncouple glycerolipids remodeling from Pi supply.
Many strategies, one aim. How viruses manipulate hosts and vectors for transmission: Rome – Rome
The Rome project will show which host and vector traits are modified by the viral infection for a better transmission, which viral factors provoke these changes, and which host and vector genes and pathways are targeted by two viruses using opposing strategies for their transmission.
Epiphytism as a Fungal Ecosystem conquered by Vascular Plants – EPIFUN
Epiphytism as a fungal ecosystem conquered by vascular plants
Metabolic mapping of gene families : a new strategy for the discovery of overlooked pathways – METAMAP
description of plant metabolites and of their biosynthetic pathways. Recent knowledge acquired on plant genomes [...] the model plant Arabidopsis thaliana. We used the largest multigene family involved in plant metabolism [...] overlooked aspects of plant secondary metabolism, in a first step in A. thalania and plants with sequenced genomes
