Table 4 Biological comparisons. Expression of genes in ethylene biosynthesis and signal transduction cascade as calculated with six different methods. Numbers in brackets after a gene name show how many genes of a family are on the microarray, followed by the size of the family. Expression data of a gene family is the summation of expression of the individual gene members. The columns with a p showing the significance of the fold change ('x' columns) between air control and ethylene (eth) treated plants. ns = not significant * = p < 0.05, ** = p < 0.01, *** = p < 0.001.

From: How to decide? Different methods of calculating gene expression from short oligonucleotide array data will give different results
