The toxic effect of aluminium was studied in germinating seedlings of mung bean (Vigna radiata) by taking different concentrations viz. 8×10−4, 10−3 and 5×10−3 M of aluminium sulphate. Nitrogen content declined with an increase in aluminium concentration. The buffer soluble fraction of total protein, however, showed an increasing trend due to Al-toxicity. The increased intensity of three major polypeptides (Rmf 0.14, Rmf 0.51 and Rmf 0.68) in SDS PAGE profile, however, was in accordance with increased status of protein level in Al-toxicity induced germinated seedlings. Free amino acids and free proline increased with increase in concentration of Al2(SO4)3, a phenomenon common with any type of stress influence.
