Changes, variations, and correlations of the fungal toxin genes. a Comparison of each mycotoxin gene copy number among the different occupant groups. b Changes in the mycotoxin gene copy number and microbial quantity over time. c Comparison of mycotoxin gene expression at different sampling times. d Correlation network analysis between mycotoxin genes and the surface mycobiome (p < 0.05, Spearman’s coefficient > 0.4). Each node represents taxa affiliated at the genus level (based on ITS1 rRNA), and the size of each node is proportional to the relative abundance of the genus. The lines between the nodes indicate positive connections among the genera. Each node is labelled at the module level
