Effect of phosphorus deficiency on PMEase activity in cotton, wheat and rice was investigated. Seedlings grown with and without phosphorus added to the growth medium using pNPP substrates at different pH levels showed that PMEase activity in cotton seedlings was 68-69% higher in without and 55-56% with phosphorus added to growth medium than rice and wheat seedlings in pNPP substrate, whereas in 4-MUP substrate PMEase activity in cotton seedlings was 68-70% higher than those of rice and 61-62% in wheat seedlings. All plant species displayed higher PMEase activity when grown in growth medium without phosphorous than the plants grown in growth medium with phosphorus.
