Overview of RNA-Seq data. A Volcano-plot of differentially expressed genes (DEGs) from the stressed group compared with the control in Zizania latifolia and Ustilago esculenta, respectively. Blue- and red-colored splashes represent significantly upregulated and downregulated genes. Blue-colored splashes represent genes without significant differences in their expression levels. B Gene ontology (GO) classification of DEGs between stressed culms and the control in Z. latifolia and U. esculenta, respectively. Along the horizontal axis is the enriched GO term, and on the vertical axis is the number of DEGs in a given term. Red- and blue-colored bars represent upregulated and downregulated genes, respectively. C Kyoto Encyclopedia of genes and Genomes (KEGG) pathway enrichment analysis of DEGs in Z. latifolia and U. esculenta, respectively. The ordinate represents the pathway name, the abscissa represents the rich factor, and the point size represents the number of DEGs in that pathway, while the point color denotes the differing Q-value ranges
