translocation

[¦tranz·lō′kā·shən]
(botany)
Movement of water, mineral salts, and organic substances from one part of a plant to another.
(cell and molecular biology)
The transfer of a chromosome segment from its usual position to a new position in the same or in a different chromosome.

Translocation

 

(1) In genetics, a type of chromosomal restructuring (mutation) involving an interchange between parts of chromosomes; it often leads to a decrease in the fertility of animals and plants.

(2) The transference of substances in and out of a cell through a biological membrane by means of a biochemical transport system.

(3) In plants, the movement of water through the xylem and of nutrients through the phloem.
