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.
