LTM Promotes Flowering Independently of Florigen and FA.

(A) Number of leaves produced by the PSM before flowering (average ± se). Wild type (n = 18), ltm-2 (n = 39), sp (n = 21), and ltm-2 sp (n = 50). Different letters mark statistically significant differences based on Tukey HSD.

(B) Number of leaves (average ± se) produced by the PSM before flowering; n = 5. Samples with different letter are significantly different by Tukey HSD.

(C) Number of leaves (average ± se) produced by the PSM before flowering; n = 4. Samples with different letter are significantly different by Tukey HSD.

(D) ltm-1, pSUC2:SFT, and ltm-1 pSUC2:SFT grown together. ltm-1 plants had eight visible leaves and no flowers, while plants ectopically expressing SFT flowered after producing three to four leaves.
