Salt stress is one of the most dramatic abiotic stresses that induce oxidative and osmotic stress simultaneously. Salt stress is known to be more effective in reducing growth and yield of glycophytes; however, halophytes are able to withstand salt stress. Nonetheless, variability exists among different halophytic plants species from different plant families. Chenopodium album belongs to Chenopodiacea family and is known as weed in many regions of world; however, it is a very interesting halophytic plant. Little research has conducted so far by considering C. album as model plant to study salt stress tolerance mechanisms. This article attempts to compile current literature in order to explain C. album salt stress tolerance mechanism and to highlight the knowledge gap relating to salt stress tolerance mechanism in C. album. Briefly, C. album has remarkable ability of seed dimorphism, sodium exclusion, and potassium retention. C. album further tolerates salt stress by increasing redox potential associated with high production of osmolytes and antioxidants.
