Enriched analysis of differentially expressed genes and expressed transcripts of TaDMT genes under sterile and fertile conditions in BS366 based on the microarray data. a The enriched biological process GO terms using differentially expressed genes in BS366. Significant enrichment is indicated by -log10 (P value). The above box indicates GO terms of upregulated expressed genes; the box below indicates GO terms of downregulated expressed genes. b The hierarchical clustering of expressed TaDMT genes according to their relative transcript levels in 10 samples. Four main clusters are indicated with colors. The letter “S” indicates sterile treatment; “F” indicates fertile treatment. The numbers at the bottom of each panel (1.5, 2.0, 2.2, 2.5, and 3.0) represent the lengths of different anther samples
