Fig 7. Real-time PCR analysis of expression of sorghum water channel gene (PIP 1;5) in 10 day-old sorghum shoots (A, C) and roots (B, D) grown in saline Murashige and Skoog medium (100 mM NaCl) supplemented with a wide range of CNTs concentrations (A, C) or graphene (B, D).

For positive control, seedlings were grown on regular Murashige and Skoog medium. For negative control, seedlings were grown on Murashige and Skoog medium (MS) supplemented with 100 mM NaCl.
