Potato (Solanum tuberosum L.) is a cheap source of carbohydrate and nutrition which is grown in different soil conditions. Phosphorus (P) is the crucial macronutrient that is involved in the metabolism in the plant such as glycolysis, respiration, formation of ATP and other catabolic and anabolic processes. Potato plant requires high P for optimum growth and development. However, under P deficiency the growth and yield of potatoes might lead to a significant reduction due to its disturbed metabolic activities. P deficiency might lead to a reduction in biomass and production, photoassimilates translocation, photosynthesis, flower formation, starch synthesis, source-sink activities and other physio-biochemical processes. The rising CO2 due to anthropogenic intervention has significantly affected plant growth and development which has ultimately affected its yield and nutritional attributes. However, high CO2 conditions might positively ameliorate the detrimental effect of P deficiency in potato plants. Improved root growth and increase in the total amount of nutrient uptake under elevated CO2 conditions might also lead to enhancement in P use efficiency even when the P acquisition efficiency declines. Overall there is an array of the physiological, biochemical and molecular mechanism and interactions work under phosphorus stress with elevated CO2 condition.
