Transcriptomic diversity of studied maize genotypes between heat and control conditions. a The PCA analysis separated expressions of identical genotypes in control and heat conditions using normalized read counts of expressed genes. b Genotypes with variable levels of absolute PC1 differences were split into three classes: large, medium, and small. The correlation of BLUPs generated from Y(II) in control and heat condition was separately calculated. c Across 102 studied genotypes, we identified upregulated genes based on the fold change of median expression value between heat and control. We then visualized these upregulated genes based on their coefficient of variations and log2 fold change of heat to control. Heat shock proteins were labeled in this graph and the blocking area demonstrated a clustered region with heat shock proteins. d Distributions of log2 fold changes of heat-to-control normalized expression values for heat shock factors identified in this study
