Abstract In this study, phytase gene (phyA2) from Aspergullus nige were transformed into genome of maize (Zea mays L.) rataria by particle bombardment. The results of RT-PCR and Western blotting detections showed that phyA2 were inserted into maize genome and expressed. The assay of phytase activity in maize plant root and utilization of phytate showed that phytase activity of plant roots was a significant factor in the utilization of phosphorus from phytate.
