Translocation is the movement of materials from leaves to other tissues throughout the plant. Plants produce carbohydrates (sugars) in their leaves by photosynthesis, but nonphotosynthetic parts of the plant also require carbohydrates and other organic and nonorganic materials. For this reason, nutrients are translocated from sources (regions of excess carbohydrates, primarily mature leaves. Translocation is the movement of materials in plants from the leaves to other parts of the plant. Nutrients, mainly sugars, are created in the leaves during photosynthesis. When two nonhomologous chromosomes mutate by exchanging parts, the resulting chromosomal rearrangements are translocations. Here we consider reciprocal translocations, the most common type. A segment from one chromosome is exchanged with a segment from another nonhomologous one, so two translocation chromosomes are generated simultaneously. Translocation in Plants has been carefully compiled and edited to meet the long felt needs of increasingly large number of those who have to deal with the different aspects of the transport of various substances from one part of plant to the other. It provides a balanced and integrated treatment of the entire field transport system. The title is intelligible to the educated layman but it deals.

Jan 08,  · Translocation in plants 1. Translocation 2. What is it? Translocation is the movement of organic substances made by the plant which are called assimilates. These are things such as sugars and other chemicals made by plant cells and are transported in the phloem tissue. Note: Citations are based on reference standards.

Define translocation. translocation synonyms, translocation pronunciation, translocation translation, English dictionary definition of translocation. n. 1. A change of location. 2. Genetics a. A transfer of a chromosomal segment to a new position, especially on a nonhomologous chromosome. b. Translocation describes the movement and distribution of radionuclides within the plant subsequent to foliar deposition and absorption by the leaves. For radioecological assessments, translocation is especially important for plants that are partly used as human food .

translocation. the transport of organic substances in the PHLOEM of higher plants, the mechanism for which is not fully understood. A popular theory is by MASS FLOW but there is evidence that there is active uptake of solutes into the sieve tubes of phloem involving the use of ATP. Mechanism of translocation • Munch Pressure flow hypothesis • Sugar loaded into phloem • increase in solute potential • leads to increase in water uptake from xylem • . Translocation In Plants [A. S.

The unit of translocation may be a chromosome (chromosomal translocation) or a chromatid (chromatid translocation). Types of Translocation: Translocation may be classified on the basis of the trans-located segment being present in the same, homologous or non-homologous chromosome, and the number of breaks involved in the translocation.
