Research departments

Biomass, Environment, Adaptation and Metabolism

BEAM 11 teams

The BEAM department frames its research in the following three thematic areas: (1) plant signaling and communication, (2) metabolic adaptation to challenging environments, (3) from plants to bioproducts for a sustainable bioeconomy.

Biological Question

The BEAM Department is active in three different fields:
1. Plant signaling and communication to unravel plant hormone and nutrient signaling, and understand the complex plant-plant and plant-microorganism interactions that exist in nature (allelopathy).
2. Metabolic adaptation to challenging environments to tackle the geographical, environmental and developmental phytodiversity, and understand the fundamental processes driving plant carbon and nitrogen metabolism.
3. From plants to bioproducts for a sustainable bioeconomy to develop biological and chemical engineering (lignocellulosic feedstock and seed quality) for a sustainable bioeconomy.


Models, tools and methods

The BEAM department uses:
1. A large number of plant models, including Arabidopsis, Barley, Brachypodium, Broomrape, Camelina, Miscanthus, Pea, Physcomitrella, Tomato, Maize and Wheat.

2. Several microbial models, including the necrotrophic fungus Botrytis cinerea, the necrotrophic bacterium Erwinia amylovora, the endophytic beneficial fungus Serendipita indica, the arbuscular mycorrhizal fungus Rhizophagus irregularis and the non-symbiotic nitrogen fixing bacteria Azospirillum sp.

  3. A large spectrum of methodological approaches carried out on different organs and different scales of plant organization:
·       structural chemistry and biochemistry
·       phenotyping in controlled environment and field conditions
·       phenotyping from cellular to whole plant level
·       forward and reverse genetics
·       quantitative genetics
·       molecular physiology
·       plant systems biology


Societal and economical impacts

The BEAM Department is at the center of the greatest challenges posed by increasing requirements for food, feed and renewable industrial resources within the framework of environmentally friendly agriculture. Consequently, BEAM teams interact in innovative projects with industrial partners and/or technical institutes:
