Abstract:
Although the link between phytochrome and plant hormones seems well established, the closeness of the relationship is in many cases still highly debatable.
The influence of light through phytochrome on hormones level could be due to the effects on: biosynthesis, release from bound forms, degradation, transport and inhibitors or cofactors of hormones action.
Phytochrome could also alter the responsiveness of the cells to hormones.
The interrelation between phytochrome and particular groups of plant hormones is discussed.
