To evaluate these probes, multiple tissues (differentiating xyle, leaf and whole-root) of a pure P. deltoides and a hybrid (P. deltoides X P. trichocarpa) were transcript profiled for identification of one or more probes that are not biased towards one or the other genotype.2008/09/10GSE12492GSM313773GSM313719GSM313780GSM313718GSM313779GSM313778GSM313775GSM313720GSM313774GSM313799GSM313777GSM313776716912492Populus deltoides Populus trichocarpa x Populus deltoides Populus trichocarpa
