The SAG12 gene was transferred into the apical point of maize plant of inbred line ’Zheng 58’ by Agro-bacterium tumefaciens mediated transformation to study the feasibility of this system.21 transgenic plants were obtained after selecting with 300mg/L Basta and 14 of them were confirmed positive by PCR amplification.The frequency of transformation reached about 12.73%.The result showed that the foreign gene has integrated into maize genome and the apical point of maize plant can be used as receipt sporophyte for transformation.
