a Clusters 1–4 show the differential accumulation of differentially changed proteins (log ratio expression) between treatments (Figure S3B). Cluster 1 represents the decreasing protein abundance from the well-watered to drought-stressed and recovery samples. Cluster 2 shows the increasing protein abundance pattern from the well-watered to drought-stressed but decreasing from drought-stressed to recovery samples. Cluster 3 represents the decreasing protein abundance when comparing well-watered to drought-stressed but increasing from the drought-stressed to recovery samples. Cluster 4 shows the increasing abundance of proteins from well-watered to recovery samples.
