The relative expression to reference genes (RE = 1) for biosynthesis transcription factor genes (A) MYB3, (B) MYB8, (C) MYB78, (D) bHLH2, (E) bHLH4, and (F) WRKY1 in young cones of HLVd-free and infected plants of hop cultivars. Probability level: *—p < 0.1, **—p < 0.05, and ***—p < 0.01. Note: straight line—median; dashed line—average; and box—95% percentile ± standard deviation.
