translocation
translocation
1. The movement of dissolved substances within a plant, usually from the site of synthesis or uptake to centres of growth or storage.
2. A change in the arrangement of genetic material, altering the location of a chromosome segment. The most common forms of translocation are reciprocal, involving the exchange of chromosome segments between 2 non-homologous chromosomes. A chromosomal segment may also move to a new location within the same chromosome or in a different chromosome, without reciprocal exchange; these kinds of translocation are sometimes called transposition. 3. The movement of soil materials in solution or in suspension from one horizon to another.
