Schematic summarizing accumulation of transcripts in the shoot bud and developing shoot. AcBFT2 (blue) accumulates at growth cessation and during dormancy in the bud. Undifferentiated meristems in the axils of leaf primordia are indicated by black dots. AcFT (red) accumulates with winter chilling and dormancy release. Shoot outgrowth is marked by expression of AcCEN4 (dark green) and to a lesser degree AcCEN and AcCEN3, accompanied by accumulation of AcFT1 (yellow). Subsequently, AcFT2 (orange) accumulates in large, basal leaves. This expression is dynamic, declines with maturation, and is similar to that reported for AcFT. Dynamic accumulation of AcFT during flower and fruit development, but decline at maturation was also described (Varkonyi-Gasic et al., 2013). AcCEN1 (gray) is potentially associated with fruit development. AcCEN (light green) and to a lesser degree AcCEN4 accumulate in developing (latent) buds during active shoot growth. Subsequently, AcCEN declines and AcBFT accumulates with the onset of dormancy. Potential FT protein movement is indicated by colored curved arrows.
