Abstract
Many studies have reported that cyclin-dependent kinase inhibitor 3 (CDKN3) is involved in the cell cycle. However, the function of CDKN3 has not been well elucidated in organisms. In this study, a multiallelic indel caused by a 19-bp fragment and a 2 × 19 bp fragment was shown for the first time to be inserted into the promoter of the CDKN3 gene in 1994 chickens from 9 different breeds. In addition, 6 genotypes (C5C5, C4C4, C3C3, C4C5, C3C4, and C3C5) were observed (C3C3, C4C4, C5C5 have 3 × 19 bp, 4 × 19 bp, and 5 × 19 bp, respectively). Among these genotypes, the C4C4 genotype was the most dominant genotype in 9 breeds. The results of χ2 analysis of CDKN3 gene in different breeds showed that there were significant differences in the distribution of genotypes among different cultivars (P < 0.01). In addition, association study with F2 chicken resource population which produced by Anka and Gushi chickens showed that the C3C4 genotypes had the greatest semi-evisceration weight (SEW, 1163.94 ± 46.84), evisceration weight (EW, 964.15 ± 41.16), head weight (HW, 45.55 ± 1.43), claw weight (CW, 63.42±2.86), wing weight (WW, 129.15±5.48), liver weight (LW, 29.96±1.27), carcass weight (cW, 1286.96±49.53), weight at 10 (1190.68±45.68) and 12 (1430.65±54.45) wk, followed by C3C3, C4C4, C5C5, C4C5, whereas C3C5 genotypes having the lowest SEW (989.21±47.71), EW (841.38±40.55), HW (41.03±1.46), CW (54.36±2.81), WW (116.31±5.39), LW (27.31±1.25), cW (1093.29±49.99), weight at 10 (1036.10±44.99) and 12 (1246.28±53.59) wk. Expression levels of CDKN3 in breast muscle of chickens with C4C4 (0.72±0.02), C3C3 (0.95±0.41), and C4C5 (0.74±0.13) genotypes were significantly lower than those with C5C5 (1.80±0.01) and C3C5 (2.14±0.17) genotypes (P < 0.05). In conclusion, we investigated the effect of a multiallelic indel in the CDKN3 gene on the economic traits of chickens, and this indel was significantly associated with growth and carcass traits in chickens. Collectively, our findings provide useful information about the repeat sequence indel in the promoter region of the CDKN3 gene as a potential molecular marker for chicken breeding.
