Trees are an important component of the global ecosystem. They dominate many regions of the world as natural, extensively or intensively managed plantations. The Fagaceae family comprises about 1,000 woody species distributed throughout the northern hemisphere. About half belong to the Quercus (oak) genus. These oaks have traditionally high cultural and societal values. As other forest tree species, they are also providing important environmental (carbon sequestration, water cycle, reservoir of biodiversity, soil protection...) and economic (carpentry, furniture, cabinet making, veneer, cask industry, fuelwood, hunting and fungus gathering) services. Finally these long-lived organisms are considered as relevant models to study both short and long term adaptation mechanisms to abiotic and biotic constraints associated with global change, as they grow under a wide range of environments (soil and climate). The goal of this project is to sequence the complete genome of a highly heterozygous oak individual (Quercus robur, accession 3P). This genomic resource will allow to discover which genes are involved in the adaptation of oak individuals to their environments and to study their adaptive potential under current and future climate changes.
