Figure 5. Effects of girdling on the expression of genes associated with starch and sucrose metabolism pathways.

The values in red and green indicate log₂ fold increases and decreases, respectively, in expression in partial girdled (PG) and fully girdled (FG) leaves compared to control leaves. Each row represents the expression pattern of a specific gene. Each column represents a different experimental condition. Experimental conditions 1–6 (left to right) are leaves from 120-day-old plants that were developing storage roots: (1) 0 h PG leaves, (2) 0 h FG leaves, (3) 2 h PG leaves, (4) 2 h FG leaves, (5) 4 h PG leaves, and (6) 4 h FG leaves; conditions 7–10 (left to right) are leaves from 45-day-old seedlings that have no storage roots developed: (7) 0 h PG leaves, (8) 0 h FG leaves, (9) 2 h PG leaves, and (10) 2 h FG leaves.
