Important losses in poplar productivity occur because of susceptibility to microbial pathogens. To enhance disease resistance in susceptible genotypes, the gene coding for D4E1, a synthetic antimicrobial peptide consisting of 17 amino acid residues, was introduced into poplar (Populus tremula L. x Populus alba L.) via Agrobacterium-mediated transformation. Four kanamycin-resistant transformants...

This paper is to give an outline of the tree biotechnology research in South Korea. Tree Breeding, we call Traditional Tree Breeding later compared to Tree Biotechnology, started in 1954 in South Korea. Tree Biotechnology Research started as Tissue culture in the late 1970 in South Korea. Micropropagation was the first field adopted. Embryo culture, Bud culture, Callus culture, Cell culture are...

carbon sequestration into plants biomass, especially in fast growing trees is an easier and economically way for dropping off co2 from atmosphere. this study was carried out in order to investigate above-ground biomass of white poplar (populous alba, l.) plantations that was planted in fourdifferent plant spacing (0.5 × 0.5, 1×1, 2×2 and 4×4 m.) in chaharmahal and bakhtiari province in west of ...

2 A b s t r a c t 2 4 Complete Populus genome sequences are available for the nucleus (P. trichocarpa; section 2 5 Tacamahaca) and for chloroplasts (seven species), but not for mitochondria. Here, we provide the 2 6 complete genome sequences of the chloroplast and the mitochondrion for the clones P. tremula W52 2 7 and P. tremula x P. alba 717-1B4 (section Populus). The organization of the chlo...

during the study on rust mycobiota of central alborz, several rust infected specimens belonging to salicaceae family including populus and salix species were investigated. populus nigra, p. euphratica, saix alba and s. excelsa were infected by various melampsora species. uredinial (ii) and telial (iii) stages of rust were present on infected plants. according to morphological characters, five f...
