Correlation and statistical analysis
To measure the linear dependence between the variables, Pearson’s
correlation coefficient was calculated using R statistical package. Heat
maps were generated based on correlation values of metabolites and
hormones. Circos plot represents the relationship between hormones and
metabolites, which was generated based on correlation values of
individual metabolites and hormones. The statistical significant
differences of control and salt-treatments were calculated by using
one-way ANOVA at P < 0.001, P < 0.01 and P
< 0.05.
