图6 共表达网络分析 (a) 模块系统树图。(b) 模块与含油量相关性。(c) 模块中基因数目对比。(d) 基因网络图。八边形红色节点代表候选基因, 根据功能标注, 共表达网络分为油脂生物合成过程(红色节点)、油脂转运(紫色节点)、油脂氧化(橙色节点)、光合作用(绿色节点)和碳水化合物代谢过程(灰色节点)。

Fig. 6 Coexpression network analysis (a): dendrogram of module system. (b): correlation between modules and oil content. (c): comparison of gene numbers in modules. (d): gene network diagram. Octagonal red nodes represent candidate genes, and according to functional labeling, co-expression networks are divided into: lipid/fatty acid biosynthesis (red nodes), lipid transport (purple nodes), lipid/fatty acid oxidation (orange nodes), photosynthesis (green nodes), and carbohydrate metabolism (gray nodes).
