Fig 4. Ratios of gene expression for 47 AP2/ERF genes of Hevea brasiliensis in response to latex harvesting stress in mature trees and various types of abiotic stress in juvenile plants.

Up-regulated genes are shown in bright red for a threshold value ≥ 5, dark red for a value 2<n<5, and down-regulated genes are shown in bright green for a threshold value ≤ 0.2, dark green for a value 0.5>n>0.2. The non-significant fold changes are shown in a dark colour.
