The expression pattern of BBX genes in Saccharum hybrid YT55 and YT00–236 under low-nitrogen stress conditions based on log2-transformed FPKM values (a) and verification of BBX1 and BBX13 expressions in root and leaf under low-nitrogen stress by RT-qPCR (b, c, d, and e). YT55 and YT00–236 seedlings were subjected to 100 mM nitrogen treatment, and samples were collected at 0, 6, 12, 24, 48, and 72 h after the treatment. The expression at 0 h was set to 1.0. Values are mean ± SD of three replicates
