The ectomycorrhizal symbiosis represents a complex biological system involving multifaceted interactions between the two partners. The establishment of the symbiosis depends on various conditions (e.g. climate), but also on the genetic traits of the partners. To evaluate the impact of the genetic predisposition on the development and functioning of ectomycorrhizas, we compared the transcriptome of roots from Populus trichocarpa and Populus deltoides colonized with Laccaria bicolor.2011/01/15GSE26416GSM648411GSM648401GSM648403GSM648414GSM648405GSM648408269926416 Populus deltoidesPopulus trichocarpa
