Fig. 6: Comparisons of single-cell transcriptomes among maize, rice, and Arabidopsis root tips.
From: Single-cell transcriptomes reveal spatiotemporal heat stress response in maize roots
A, B UMAP visualization of distinct cell types in root tips between maize and rice (A) or Arabidopsis (B). C, D Heatmap showing the correlation among different cell types in root tips between maize and rice (C) or Arabidopsis (D). The r value represents correlation coefficients. E Sankey diagram illustrating that maize shares a high degree of similarity in cortex and endodermis with rice and Arabidopsis. The number of overlapped orthologous genes for each cell type is indicated on the top of each cluster. F GO enrichment analysis for orthologous genes conserved between maize and Arabidopsis. G Volcano plot showing the common DEGs of cortex in maize and Arabidopsis under HS. H, I Venn diagram of upregulated genes (H) and downregulated (I) genes in cortex cluster between maize and Arabidopsis under HS. J GO enrichment results for co-upregulated cortex genes between maize and Arabidopsis. K, L Violin plot illustrating the HS response of two homologous genes, Cypbc7 and HSA32, in the cortex of maize and Arabidopsis (ScRNA-seq, ****represents p < 0.0001). Statistical significance was tested using a two-tailed t test. M GO enrichments for 1288 genes specifically upregulated in maize under heat shock. Hypergeometric tests in ClusterProfiler software were used to test the statistical significance of GO terms in (F, J, and M).
