Fig. 4From: Transcriptomic analysis reveals hub genes and subnetworks related to ROS metabolism in Hylocereus undatus through novel superoxide scavenger trypsin treatment during storageROS related PPI networks induced by trypsin were constructed by Cytoscape software. Rectangle nodes represent proteins encoded by downregulated genes; Round nodes represent proteins encoded by upregulated genes. Triangle-shaped nodes represent the last interacting proteins without significantly different expression. The top 6 clusters calculated by MCODE were colored as shown in the legendBack to article page
