| Popis: | For many of the new breeding techniques sequence information is of the utmost importance. In addition to current breeding techniques, such as marker-assisted selection (MAS) and genetic modification (GM), new breeding techniques such as zinc finger nucleases, oligonucleotide-mediated mutagenesis, RNAi and cisgenesis are totally dependent on knowing gene or allele sequences. Many plant species have been fully sequenced, but none of them represents an ornamental crop, let alone a member of the monocotyledonous, bulbiferous geophyte order, such as the Liliales. For a limited number of these flower bulb species, some EST-libraries have been generated and a similarly low number of promoters and genes have been isolated, characterized, or used for transformation. Most of the functional analyses and applications in genetically modified crops were ectopic, i.e., not in flower bulb crops themselves. Genes and promoters originating from other organisms have been used in GM of flower bulbs aiming for the introduction of disease resistance or the modification of flower traits. In order to enhance consumer acceptance of transgenic GM flower bulbs and to facilitate obtaining EU approval for cultivation and market introduction, the marker-free technology is being tested. |
