Relative expression was expressed as fold changes with respect to expression levels in feather samples from three non-vitiliginous SL chickens (calibrator sample).
Mean ± SEM of the 7 SL chickens’ highest expression level of each target gene during SLV development.
Mean time ± SEM (n = 7) in weeks (with respect to SLV onset; week 0) when highest expression occurred.
Time in weeks with respect to SLV onset (week 0) when targets were significantly (P ≤ 0.05) elevated compared to pigmented growing feathers collected from the 7 SLV chickens more than 2 weeks before SLV onset (BV samples). Also see Figure 3.
