31019b

31019b is an engineering strain of Saccharomyces cerevisiae used to study the function of plant ammonium transporter. Its key feature is that many endogenous ammonium transporter genes (such as MEP1, MEP2, MEP3) in the genome are knocked out, which leads to its inability to absorb ammonium ions and becomes an ammonium transport defect type. Therefore, when exogenous plant ammonium transporter genes (such as OsAMT1 of rice; 1) After expression and functional compensation in this strain, the strain recovered its ability to grow on the medium with ammonium as the sole nitrogen source. The model supports accurate quantitative absorption experiments with 15N stable isotopes, and is an important tool to study the absorption mechanism of ammonium in plants.
