Cu toxicity induces the expression of OsGLP8-2 in rice. Transcription levels of OsGLPs increased under heavy metal treatment. Total RNA was isolated from the roots of 4-day-old WT (wild type) rice seedlings treated with 3 μmol L⁻¹ CuSO₄ for 12 h and used for transcriptome sequencing. Values are the mean ± SD; n = 3. Fold change ≥ 2 and FDR ≤ 0.05.
