Abstract:
Total DNA of B. amyloliquefaciens and S. aureus were isolated and cut partially with Hind Ⅲ Separately, The genes for barnase and for staphylococcal nucl ease were obtained by PCR and cloned into pGEM7Z-f(+), The sequencing show that the n ucleotide (nt) sequence of the barnase is 99.3% homologous with the previously determimed sequence and the deduced animo acid (an)sequence found to correspond precisely to the previously determined sequence; the nucleotide (nt) sequence of the staphylococcal nuclease is 99.1% homologous with the previously determined sequence and the deduced amino acid (an) sequence 99.3% homologous with the previously determinded sequence.These have built basis of making use of special expression or activation of nuclease to produce the male sterility plant by plant gene engineering and to explore new antiviral strategy.
