OsALKBH9 affects the expression of genes related to male reproductive development and exine accumulation. (a) Venn diagram depicting the differentially expressed genes (DEGs, Osalkbh9‐1/WT) at stage 7 to stage 8 and stage 9 to stage 10. (b) Gene ontology analysis of the co‐upregulated and co‐downregulated genes at stage 7 to stage 8 and stage 9 to stage 10. Left part indicates the co‐upregulated genes, while right part indicates the co‐downregulated genes. CC, cell component; BP, biological process; MF, molecular function. (c) qRT‐PCR detection of genes required for tapetum development and pollen wall accumulation. UBQ was used as an internal control. Data are means ± SD for three biological replicates. Student's t test: *(P < 0.05), **(P < 0.01).
