图3. 脆枝青藓相关基因的相关性分析。A, 15个显著的气孔相关节律性基因主成分(PC)分析图。B, 57个显著的碳固定相关节律性基因相关性图, 红色表示正相关, 蓝色表示负相关。C, 159个显著的光合相关节律性基因相关性图。热图采用了归一化表达量, 范围为-1到1。蓝色区域代表高表达量, 而红色区域则代表低表达量。ACA10, Ca^{2 +}-ATP酶10; AHA5, 质膜H⁺-ATP酶; AHA10, H⁺-ATP酶10; MTC, PSII反应中心相关的膜内捕光复合物; OST1, 气孔开放因子1; PEX, 光系统II (PSII)外围蛋白质; PIP2;1, 水通道蛋白PIP2-1; P_n, 净光合速率; T_r, 蒸腾速率。

Fig. 3. Correlation analysis of genes related to Brachythecium thraustum. Principal Component (PC) analysis of 15 significant stomatal-related rhythmicity genes (A), 57 significant carbon fixation-related rhythmicity genes correlation plot (B) and 159 significant photosynthesis-related rhythmicity genes correlation plot (C) of Brachythecium thraustum. Red color indicates positive correlation, blue color indicates negative correlation. The heatmap used normalized expression levels, ranging from -1 to 1. In this scheme, blue regions represent high expression levels, while red regions represent low expression levels.
