Abstract:
Heavy metal ions which are not essential elements for basic metabolism severely threaten human health through food chain. As the most water-soluble and absorbed heavy metal ion, Cadmium (Cd) is easily accumulated and contaminates plants. Previously, mitochondrial pyruvate carrier 1 (MPC1) was proved to be required for Cd tolerance and Cd2+ exclusion. In this study, we carried out following mRNA expression profile analysis on Cd-treated mpc1-1 and wild-type plants. After further selection of differential expressed genes and Cd tolerance tests in yeast, we have discovered a novel Cd tolerance related gene: AGP30, which specifically expresses in root and is significantly regulated by MPC under Cd stress. This protein mainly localize in the cell wall of cells in root meristem region, which was consistent with our former Cd2+ flux measurement. In conclusion, our work discovered a new Cd resistant gene for utilizing in transgenic crops for preventing Cd2+ influx.

Pyruvate Oxidation
First, the enzyme pyruvate dehydrogenase removes the carboxyl group from pyruvate and releases it as carbon dioxide. The stripped molecule is then oxidized and releases electrons, which are then picked up by NAD+...

Electron Carriers
Over the many stages of cellular respiration, glucose breaks down into carbon dioxide and water. Electron carriers pick up electrons lost by glucose in these reactions, temporarily storing and releasing them into the electron...
Fates of Pyruvate
In aerobic organisms, pyruvate is metabolized via the citric acid cycle to produce reduced coenzymes NADH and FADH2. These coenzymes are then oxidized in the electron transport chain to produce ATP and, in the process, regenerate the NAD+ and FAD. As seen in some cell types and organisms, fermentation...
