Expression patterns (Zscore) of transcription factors upregulated in the gametophore apical cell. The horizontal axis of the heatmap represents the pseudotime. Dashed gray lines indicate gametophore apical cells enriched pseudotime. The color code from blue to red indicates gene expression changes (log2fold change value) after cytokinin (BAP) treatment. Genes with an Mvalue of less than 0.1 in bulk RNA-seq are considered low-expression genes.
