Box plot representation of raw C
values obtained from amplification curves for reference genes. Lower and upper boundaries of each box indicate the 25th and the 75th percentile, respectively. Ranges are represented as bars (whiskers) below and above the box and indicate the 10th and 90th percentiles, respectively. The horizontal line in each box represents mean and outliers by (•). SAND: SAND family protein; GAPDH: glyceraldehyde 3-phosphate dehydrogenase; EF1-a: elongation factor1-alpha; Ubiquitin: ubiquitin-60S ribosomal L40 fusion protein; Actin, NAD5: NADH dehydrogenase subunit 5.
