This research aims to study the proteins transformation in zea maize plant seedlings cells, (GHOTA 82) under the influence of phyto hormone Auxin & grothregulators 2,4-D and IBA. Maize plant seeds were germinated in water medium for six days in darkness and temperature of 25 ºC. The quantity different groups of proteins, were analyzed in the stem cells of the developing seedling mesochotyles after incupation in darkness water and in different solutions of auxin, 2, 4D & IBA (in concentration 50 mg/l) for 20 hours in 26 ºC. The results showed that had inhibition effects on hydrolysis of protein groups in zea maize plant seedlings cells.
