FAQ
Frequently Asked Questions
No, it is not a single simple hormone. The 'florigen' concept refers to a mobile flowering signal, now known to involve a protein (like FT) that forms a complex to perform this function.
The specific molecules may vary, but the concept of a mobile signal that induces flowering in response to environmental cues is widespread among flowering plants (angiosperms).
Understanding the florigen pathway is crucial for agricultural biotechnology, allowing scientists to manipulate flowering time for crop improvement, but it is not a direct commercial product like a fertiliser.
Some plants have 'anti-florigen' signals, like TFL1 in Arabidopsis, which maintain vegetative growth and delay flowering.
