Figure 4. GA₃ induced flowering and EaLFY expression.

(a) The size (length x width (cm²)) of the young fully expanded leaf was recorded weekly. Data plotted were the average (n = 5) ±s.d. Arrow indicates the time of GA₃ treatment. (b) Appearance of flower bud (white arrow) in VG plants. (c) Appearance of small flower bud (white arrow) in HG plants. (d) Inflorescence consisting of a leaf-shaped spathe and a spadix. (e) Close-up of inflorescence with many small, pentacyclic and prism-shaped female flowers (black arrows) tightly packed together. (f) Stamen of a male flower with anthers (yellow arrows) hidden between female flowers. (g) RT-PCR results of EaLFY and 18s rRNA from three GA₃ treated (+GA₃) and three untreated (−GA₃) VG (upper panel) and HG (lower panel) plants.
