A year and a half after the publication of the complete sequence of the pedunculated oak genome by a national consortium led by INRAE and CEA (Genoscope), the first results based on this genomic resource are the subject of a series of articles published on 16 April 2020 in the journal New Phytologist.
These new results clarify the evolutionary history of oaks,
from the deep roots of their diversification to the more recent evolution of
European white oaks, as well as the identification of key genes involved in
adaptation to certain environments or in resistance to pathogens.
As keystones of forest ecosystems, trees - and oaks in
particular - are also considered as model organisms for identifying the
ecological and evolutionary processes responsible for the diversification and
adaptation of plants to their environment.
Of the ten or so articles published in the journal New
Physiologist, seven are co-authored by INRAE researchers, four of which are the
result of cooperation between the BIOGECO research unit based in New
Aquitaine and the unit's long-standing partners: the Morton Arboretum in
Chicago and the Genoscope at the François Jacob Institute of Biology (CEA).
Through these various articles and thanks to the data
generated by the Genoscope, the researchers have highlighted several points :
Finally, research articles illustrate the publication of
these synthetic and prospective works on the oak genome sequence.

These results were the subject of a press release (in french).
