Malate transport and metabolism play essential roles in cell proliferation and inflorescence development in developing ears. A, DEGs involved in the AOX pathway at all three stages. B, Differential expression of malate metabolism-related genes. (1) MS (Zm00001d003247); (2) NADP-ME (Zm00001d043601); (3) pMDH (Zm00001d041243); (4) NADP-ME (Zm00001d003090); (5) NAD-ME (Zm00001d013911). C, Malate metabolism is involved in multiple processes and malate can be easily transported across cell membranes separating various compartments through its transporter (indicated as a blue transmembrane structure). The numbers are the same as in (B). D and E, DEGs involved in DNA replication (D) and inflorescence development (E) are broadly expressed at lower levels in ead1 relative to WT at all three stages.
