Additional file 4 of Genome-wide analysis of spatiotemporal expression patterns during rice leaf development

Additional file 4:. Three-dimensional model of Fig. 2. A three-dimensional model of PCA score plot of samples based on the modified principal components. The proportions of the total variance explained by PC1, PC2, and PC3 are shown in parentheses. Samples collected at the same stage are shown in the same color. Samples with different tissue identities are indicated by different symbols: shoot apex, square; P3 leaf, circle; blade, triangle; blade-sheath boundary, diamond; sheath, inverted triangle. Red arrows represent the directions of the original principal components (PC1, PC2, and PC3) shown in Supplemental Figure 4.附加文件4：图2的三维模型。该模型为基于修正主成分分析(Principal Component Analysis, PCA)的样本主成分得分图三维模型。PC1、PC2及PC3所解释的总方差占比标注于括号内。同一发育阶段的样本以相同颜色标识。不同组织类型的样本采用不同符号标注：茎尖使用方形、P3叶使用圆形、叶片使用三角形、叶鞘接合处使用菱形、叶鞘使用倒三角。红色箭头代表补充图4中展示的原始主成分（PC1、PC2与PC3）的方向。
