查询词典 embryonic cell

A trivalent plant expression vector containing Bt cry1Ah gene, cry1Ie gene and glyphosate-tolerant 2mG2-epsps gene was constructed, glyphosate isopropylamine salt as a screening agent, 2mG2-epsps gene as a selectable maker gene. The vector was transfer into maize immature embryonic calli by microprojectile bombardment, and 69 T0 generation plants were obtained. PCR analysis showed that 17 plants had the integration of insect-resistant cry1Ah, cry1Ie gene and glyphosate-tolerance 2mG2-epsps gene.
