Figure 2

Expression profiles of barley genes responsive to drought. Expression ratios (drought vs control) are colour-coded: dark yellow >6 fold up-regulated, black no change, violet >6 fold down-regulated. The proportion of genes within a given functional transcript group is shown in the corresponding pie chart on the right with significantly overrepresented gene categories marked by star symbol. Each gene is represented as horizontal row (for order, see Additional file 3) and developmental stages are detailed in the vertical columns (d: days of exposure to drought and %SWC: soil water content). Gene expression data refer to cvs. Brenda (B), Morex (M), Morocco (Mo), Martin (Ma), Oregon Wolf Barley-Dominant (OWB-D), Oregon Wolf Barley-Recessive (OWB-R), Hs (H. spontaneum HS584). Expression data from individual replications are given in Additional file 3.
