The 1.5 kilobase promoter sequence upstream of Dc8, a late embryo abundant gene of Daucus, fused to the reporter β-glucuronidase gene was introduced into several tissues of Picea abies via a custom-made electric-discharge particle accelerator. Transient expression was measured histochemically as spot number 2 d after bombardment. Embryogenic suspensions(More)
Bipartite constructs ofAgrobacterium rhizogenes strain LBA 9402 or A4RSII induced transformed roots on the hypocotyls ofPinus contorta following inoculation, LBA 9402 being more effective. The developmental sequence of root formation and morphology following infection were studied. Furthermore, the pattern of gene expression was studied during rooting and(More)
