It is evident from previous reports that 5-aminolevulinic acid (ALA), like other known plant growth regulators, is effective in countering the injurious effects of heavy metal-stress in oilseed rape ( Brassica napus  L.). The present study was carried out to explore the capability of ALA to improve cadmium (Cd 2+ ) tolerance in  B .  napus  through physiological, molecular, and proteomic analytical approaches. Results showed that application of ALA helped the plants to adjust Cd 2+ -induced metabolic and photosynthetic fluorescence changes in the leaves of  B .  napus  under Cd 2+  stress. The data revealed that ALA treatment enhanced the gene expressions of antioxidant enzyme activities substantially and could increase the expression to a certain degree under Cd 2+  stress conditions. In the present study, 34 protein spots were identified that differentially regulated due to Cd 2+  and/or ALA treatments. Among them, 18 proteins were significantly regulated by ALA, including the proteins associated with stress related, carbohydrate metabolism, catalysis, dehydration of damaged protein, CO2 assimilation/photosynthesis and protein synthesis/regulation. From these 18 ALA-regulated proteins, 12 proteins were significantly down-regulated and 6 proteins were up-regulated. Interestingly, it was observed that ALA-induced the up-regulation of dihydrolipoyl dehydrogenase, light harvesting complex photo-system II subunit 6 and 30S ribosomal proteins in the presence of Cd 2+  stress. In addition, it was also observed that ALA-induced the down-regulation in thioredoxin-like protein, 2, 3-bisphosphoglycerate, proteasome and thiamine thiazole synthase proteins under Cd 2+  stress. Taken together, the present study sheds light on molecular mechanisms involved in ALA-induced Cd 2+  tolerance in  B .  napus  leaves and suggests a more active involvement of ALA in plant physiological processes than previously proposed.
