Figure 5

Biological processes in clusters 1 and 2 (see Figure 4), as revealed by analysis of GO term distribution using Blast2GO and REVIGO algorithms. GO terms are represented by circles and are plotted according to semantic similarities to other GO terms (adjoining circles are most closely related). Circle size is proportional to the abundance of the GO term in the cluster, while color indicates semantic similarities. Only GO terms with higher than 1% frequency in the cluster are shown. (A) Cluster 1. Main patterns are related to the general development of reproductive tissues, metabolism, microsporogenesis and cell-division processes and specific related fertility processes. (B) Cluster 2. Main patterns are related to energy-consuming activities and/or response to stress.
