Genes	Regulation of expression			p-values	Fold change
Late	Aswan	x	Swaymeh
SP29	-		+	p < 0.0001	5.33
SP32	-		+	p = 0.0005	7.59
SP36	-		+	p < 0.0001	6.31
SP42	-		+	p < 0.0001	6.73

Only statistically significant (p < 0.0006) differences are shown. Values of fold change are derived from the comparison between expression medians. Regulation of expression levels up (+) or down (-) are indicated.
