Venn diagram of DEGs distributed in maize inbred lines 102 and 55. The treatments included the normal control treatment (CT) and the low-temperature treatment (LT). The low-temperature-tolerant line (Zao 8–3) and low-temperature-sensitive line (Ji 853) are labeled “55” and “102”, respectively. The five treatment-line comparisons groups included the following: low-temperature treatment line 102 vs low-temperature treatment 55, upregulated expression (LT_102vsLT_55.up); low-temperature treatment line 102 vs low-temperature treatment 55, downregulated expression (LT_102vsLT_55.down); normal control treatment line 102 vs normal control treatment 55, upregulated expression (CT_102vsCT_55.up); normal control treatment line 102 vs normal control treatment 55, downregulated expression (CT_102vsCT_55.down); and candidate genes
