Ranking of the eight candidate reference genes according to the stability of their expression in samplings IM1 (top) and P1 (bottom) computed using BestKeeper and NormFinder.

1Sampling composition given in Table 1.2The three reference genes selected are in bold. TUB, beta tubulin; CAP, Capsine phosphatase; EF1, Elongation factor 1; GADPH, Glyceraldehyde 3-phosphate dehydrogenase; RUB, Ribulose-1,5-bisphosphate carboxylase oxygenase; UBQ, Ubiquitin; 18S, ribosomal RNA 18S; 25S, ribosomal RNA 25S.3Standard deviation of Cq values. SD values higher than the threshold value (1.00) are underlined.4Pearson’s coefficient of correlation.5Stability value.*associated p-value1. 取样组成详见表1。 2. 筛选出的3个内参基因（reference gene）以粗体标注。各基因缩写及对应全称如下：TUB（β微管蛋白，beta tubulin）；CAP（肌氨酸磷酸酶，Capsine phosphatase）；EF1（延伸因子1，Elongation factor 1）；GADPH（甘油醛-3-磷酸脱氢酶，Glyceraldehyde 3-phosphate dehydrogenase）；RUB（核酮糖-1,5-二磷酸羧化酶/加氧酶，Ribulose-1,5-bisphosphate carboxylase oxygenase）；UBQ（泛素，Ubiquitin）；18S（18S核糖体RNA，ribosomal RNA 18S）；25S（25S核糖体RNA，ribosomal RNA 25S）。 3.
