Gibberellins transport in plant

Gibberellins transport in plant

    • Gibberellins have been found from both phloem and xylem exudates from a variety of plants.
    • Unlike auxins, the transport of gibberellins in plants is non-polar.
    • It is believed that gibberellins are translocated through phloem according to a flow pattern which is similar to those of carbohydrates and other organic solutes.
    • However, gibberellins transport may also occur in xylem due to its lateral movement between the two vascular tissues i.e., xylem and phloem.
    • The gibberellins are not translocated in plant as free molecules but probably in their bound form as gibberellins-glycosides.
