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.
