¹The relative expression levels of the genes of respective treatment groups are expressed as means of normalized relative quantities (NRQ). Relative quantities for individual genes are scaled to the average across all unknown samples per target gene
²Within a column, values with different superscripts are significantly different from each other at P < 0.05
