Abstract:
Somatic embryogenesis was induced and the regenerated plants were obtained by higher concentrations of auxins with immature cotyledon of 55 genotypes in soybean. Bivalent insect resistant genes were transformed into immature cotyledon of soybean which have high frequency of somatic embryogenesis via Agrobacterium-mediated. The results showed that 14 genotypes possessed high frequency of somatic embryogenesis (more than 40%) among soybean genotypes from Northeast area. 2147 immature cotyledons of 5 different soybean genotypes cultured in Northeast area were inoculated with LBA4404 (including pGBI121S4ABC plasmid). 17 plantlets were obtained under Kanamicy selection. 12 plantlets showed positive reaction in PCTR and PCR-Southern detection. These analyses confirmed the presence of introduced Bt gene in soybean.

The first-ever transgenic plant was a tobacco plant developed in 1983 that showed resistance against the tobacco mosaic virus. Since then, many transgenic plants have been developed and commercialized for improving the agricultural, ornamental, and horticultural value of a crop plant. Transgenic...
