Molecular analysis of T0 Transgenic rice plants. a A 800 bp internal sequence of cry2AX1 gene was amplified by PCR from the DNA isolated from putative transgenic plants. Lanes 1 and 21, 100 bp marker; Lanes 2–17, Putative transgenic plants of ASD16; Lane 18, Non transformed control plant; Lane 19, Negative control (water); Lane 20, pUH-rtp-2AX1 plasmid as a positive control. b Southern blot hybridization analysis of T0 transgenic rice plants expressing cry2AX1 gene. DNA sample isolated from transgenic and non-transgenic plants digested with HindIII restriction enzyme, DNA fragments separated by electrophoresis, transferred to nylon membrane and allowed to hybridize with a radioactively labelled 800 bp internal sequence of cry2AX1 gene. M, λ/HindIII marker; Lanes 1–16, Genomic DNA from transgenic rice plants UR1, UR2, UR3, UR4, UR5 UR6, UR7, UR8, UR9, UR10, UR11, UR12, UR13, UR14, UR15, UR16, respectively; Lane 17, Non-transformed control plant; Lane 18, Positive control (pUH-rtp-2AX1)
