[Campbell Biology P.909] Which statement about florigen is correct? | Practice Question
Which statement about florigen is correct?
A: Florigen is a small hormone-like molecule that travels via the xylem.
B: Florigen is produced in the shoot apical meristem and travels to the leaves to induce flowering.
C: Florigen is a protein encoded by the FLOWERING LOCUS T (FT) gene, moving through plasmodesmata.
D: Florigen's activity is limited to short-day plants, as long-day plants use a different signaling molecule.
Explanation
The text states that florigen is now understood to be a protein, encoded by the FLOWERING LOCUS T FT gene, and it travels through the symplasm via plasmodesmata from leaves to the shoot apical meristem.
