Abstract | Ozone alters root growth and root processes by first reducing photosynthesis and altering foliar metabolic pathways. The alteration in foliar metabolism is reflected in lowered carbohydrate levels in the roots. This can reduce key metabolic processes such as mineral uptake and symbiotic nitrogen fixation. These changes in root metabolism will ultimately be expressed in reduced plant growth and yield. |
