Transcriptome analysis in the wild type and Zmsiz1a/1b double mutant kernels at different time points after inoculation with Fusarium verticillioides. (a) The principal component analysis (PCA) of transcriptome data from the wild type (WT) and Zmsiz1a/1b double mutant (DM) at the indicated time after mock treatment (C) or inoculation (I). PCA was performed based on FPKM values. (b) The number of differentially expressed genes (DEGs) that were up‐ and down‐regulated between mock treatment (C) and inoculation (I) at different time points after inoculation for the WT and DM, respectively. (c) Top enriched KEGG pathways of DEGs regulated by mock treatment (C) versus inoculation (I) at different time points after inoculation for the WT, respectively. hpi, hours postinoculation
