Eucalyptus is the first planted forest tree in the world mainly for pulp and paper, and more recently for energy. It is also the second forest tree whose genome has been fully sequenced by the DOE (USA), thanks to the international consortium EUCAGEN (www.ieugc.up.ac.za/) in which we have been involved since its early creation in 2003.

Our team has a well-recognized expertise in Eucalyptus functional genomics, including transcriptomic approaches and genetic transformation. Indeed, we have contributed to significantly increase the public resources by the early release of a database of more than 30,000 ESTs (http://www.polebio.scsv.ups-tlse.fr). We made significant breakthroughs in two major themes: (1) the transcriptional regulation of wood formation (mediated by MYB transcription factors) and (2) the responses to environmental stresses (via the CBF pathway). We are now also developing a new project to study the control of woody biomass formation by environment (mainly abiotic stresses).

Finally, in collaboration with plant breeders and industrial partners, we are developing marker-assisted breeding strategies to improve both wood production and quality as well as freezing tolerance.

Key words: Eucalyptus; adaptation to environmental stresses; woody biomass; wood formation; xylogenesis; lignified cell wall; biofuels; pulp; abiotic stresses; cold; drought; transcriptional regulation; transcriptome; lignin; CBF; MYB.
