Assessing co-expression network reliability using the LHC gene family. a GO enrichment of co-expressed genes in LHC of rattan. (The left is C. simplicifolius, and the right is D. jenkinsiana) b Co-expression link between the LHCAs and LHCBs of rattan. The dark nodes indicate LHCA genes, light nodes indicate rattan’s LHCB genes, orange lines indicate positive regulatory relationships between co-expressed gene pairs, and blue lines indicate negative regulatory relationships between co-expressed gene pairs. c Comparison of PCC top 300 co-expression genes in rattan and Arabidopsis LHCA1. The dark green node indicates D. jenkinsiana. The light green node indicates C. simplicifolius. The yellow node indicates Arabidopsis thaliana. The orange node indicates the LHCA1 gene of each species, the red line indicates the co-expression relationship, and the grey line shows the direct homologous relationship
