Tea plants grow in acidic soil, but to date, their intrinsic mechanisms of acidic stress tolerance have not been elucidated. Here, we assessed the tea plant response to growth on NH4+ nutrient media having different pH and iron levels. When grown in standard NH4+ nutrient solution (iron insufficient...
