Elevated Carbon Dioxide Altered Morphological and Anatomical Characteristics, Ascorbic Acid Accumulation, and Related Gene Expression during Taproot Development in Carrots.

ABSTRACT: The CO₂ concentration in the atmosphere has increased significantly in recent decades and is projected to rise in the future. The effects of elevated CO₂ concentrations on morphological and anatomical characteristics, and nutrient accumulation have been determined in several plant species. Carrot is an important vegetable and the effects of elevated CO₂ on carrots remain unclear. To investigate the effects of elevated CO₂ on the growth of carrots, two carrot cultivars ('Kurodagosun' and 'Deep purple') were treated with ambient CO₂ (a[CO₂], 400 μmol⋅mol^-1) and elevated CO₂ (e[CO₂], 3000 μmol⋅mol^-1) concentrations. Under e[CO₂] conditions, taproot and shoot fresh weights a
