Stage dependent changes of transcript and protein abundance in response to HS. The curves represent the least square fit of percentage of genes assigned to transcript (a and b) and protein clusters (c) for tetrads (blue), post-meiotic (green) and mature pollen (red). Either all assigned genes (a) or only genes detected in transcriptome and proteome (b and c) were considered. Clusters are ordered from downregulation to upregulation after HS
