From: Transcriptomic and metabolomic shifts in rice roots in response to Cr (VI) stress
Expression profile of one of the root-specific putative ABC transporter (Os08g30770) gene up-regulated during Cr-stress. Semi-quantitative RT-PCR analysis during different heavy metal stresses in root (A). The rice variety IR-64 was germinated and allowed to grow for 5 d at 37°C and then transferred to Hewitt solution for growth. After 10 d of growth, seedlings of uniform size and growth were treated with 100 μM of Cr (VI), As (V), Cd, and Pb (100 μM) under standard physiological conditions. The expression profiles of ABC transporter (B) in seedling root (R), mature leaf (ML), shoot apical meristem (SAM), various stages of panicle development (P1-P6) and seed development (S1-S5). The microarray data was collected for different rice tissues/organs and developmental stages from the Gene Expression Omnibus database (GSE6893) at the National Center for Biotechnology Information and analyzed using dChip software. The color scale (representing log signal values) is shown at the bottom.
