Gene networks of differentially expressed genes (DEGs) in chilled flower buds and late-pink buds. DEGs in chilled flower buds were identified in comparison to nonchilled flower buds while DEGs in late-pink buds were identified in comparison to chilled flower buds. The ontology file of GOSlim_Plants in BiNGO was used to identify over-represented GO terms (P < 0.05). a Comparison of the gene network in chilled flower buds to late-pink buds; white nodes and black edges are present in both gene networks; red nodes and edges are present only in the chilled buds; and green nodes and edges are present only in the late-pink buds. The number in each circle is a GO identity number. A gene network in chilled flower buds (b “Biological_process” c “Cellular component” d “Molecular function”). I, II, and III in b show GO terms related to stress, plant growth, and reproduction, respectively
