Figure 8.

Correlation network analysis for structural genes, LbaBBX transcription factors and carotenoid content. The red ellipse boxes indicated that carotenoid metabolism, the green ellipse boxes indicated that LbaBBX transcription factors, and the purple diamond boxes indicated carotenoid biosynthetic genes, respectively. The black solid lines indicated positive regulation, while the dot lines indicated negative regulation, respectively. The edges are drawn when the linear correlation coefficient is >0.8 with p-value < 0.05. The related correlation coefficients were shown in Table S8.
