Functional classification of 106 differentially accumulated proteins in response to all 3 drought stress levels. (A) The pie chart shows the percentage of different biological functions of common proteins significantly changed in abundance in response to all three drought stress levels. (B) The bar graph shows the percentage abundance of proteins in 7 functional categories that were significantly altered in response to drought stress at divergent levels. Distinct colours represent proteins significantly changed in common between stresses: severe and moderate drought (blue), severe and mild drought (orange), moderate and mild drought (grey), and overlapped between all three drought stress levels (yellow).
