Figure 7From: The dirigent multigene family in Isatis indigotica: gene discovery and differential transcript abundanceHeat map of Ii DIR transcript expression obtained after treatment with MeJA at hairy roots. A color bar indicates fold-change expression differences on a natural log scale (treatment/control). Hairy roots of I. indigotica are treated with MeJA for 0, 1, 3, 6, 12 and 24Â h. 0Â h is designed as control.Back to article page
