ABSTRACT = {Heavy metal toxicity is one of the major ecosystem concerns globally in present time and is also responsible for
significant threat to agronomic crops. The current work was conducted to investigate the possible ameliorative
role of proline in <i>Coriandrum sativum</i> L. seedlings treated with mercury (Hg). The seedlings were exposed to
different concentrations of Hg (0, 0.1, 0.3 and 0.5 mM) for 20 days. The effects of pre-sowing treatment with proline were studied on <i>C. sativum</i> seedlings in terms of pigment (chlorophylls, carotenoids and anthocyanins), malondialdehyde (MDA), antioxidant compound (glutathione, total phenolic compounds, ascorbic acid) and
osmolytes (proline, glycine betaine). Additionally, activities of antioxidant enzymes, namely catalase (CAT),
superoxide dismutase (SOD), ascorbate peroxidase (APX) and dehydroascorbate reductase (DHAR) were also
studied. A strong decline of photosynthetic pigment concentrations was observed in leaves of <i>C. sativum</i> under
Hg toxicity. Treatment of seeds with proline reduced the loss of photosynthetic pigments, counteract Hg-triggered
oxidative stress, likely preserving the functionality of antioxidant apparatus under Hg stress. The increment of
total polyphenols and glycine betaine also contributed in ameliorating Hg toxicity, suggesting the use of exogenous proline as a potential method to enhance the plant tolerance against heavy metal stress.},
