Abstract
Genetically transformed lombardy poplar (Po-pulus nigra L. var. italica Koehne) plants were regenerated after co-cultivation of stem segments with Agrobacterium tumefaciens strain LBA4404 that harbored a binary vector which included the rice gene for a homeodomain protein (OSH1) and a gene for neomycin phosphotransferase. The expression of the OSH1 gene under control of the cauliflower mosaic virus 35S promoter induced morphological abnormalities in the leaves and stems of the newly generated transgenic poplar plants. This result suggests that OSH1 can function as a regulator of morphogenesis in transgenic poplar, as it does in transgenic rice, Arabidopsis, and tobacco plants.
