Differentially expressed genes (DEGs) in Camellia oleifera ‘Huashuo’ and ‘Huajin’ cultivars and Gene Ontology (GO) functional annotation at different development periods. A Number of up/down-regulated DEGs at each developmental stage. B Venn diagram showing the DEGs shared among the four gene sets. C GO classification. A1-B1, C. oleifera ‘Huajin’ seeds in July vs. C. oleifera ‘Huashuo’ seeds in July; A2-B2, C. oleifera ‘Huajin’ seeds in August vs. C. oleifera ‘Huashuo’ seeds in August; A3-B3, C. oleifera ‘Huajin’ seeds in September vs. C. oleifera ‘Huashuo’ seeds in September; A4-B4, C. oleifera ‘Huajin’ seeds in October vs. C. oleifera ‘Huashuo’ seeds in October
