3.2.1.68 | more |
construction of a single mutant line isa2-2 by T-DNA insertion mutagenesis. The isa1-1 isa2-2 double mutant line is obtained by a cross between the two corresponding single mutants and screening of the progeny by PCR amplification of genomic DNA using a T-DNA end primer and gene-specific primers. The phenotype of the isa1-1 isa2-2 double mutant is complemented but the ZmISA1 activity |

construction of single mutant line isa1-1 by T-DNA insertion mutagenesis. The isa1-1 isa2-2 double mutant line is obtained by a cross between the two corresponding single mutants and screening of the progeny by PCR amplification of genomic DNA using a T-DNA end primer and gene-specific primers. The phenotype of the isa1-1 isa2-2 double mutant is complemented but the ZmISA1 activity, Zea mays ISA1 subunit is expressed via transfection with Agrobacterium tumefaciens strain GV3101 in Arabidopsis thaliana lacking endogenous ISA1 or lacking both native ISA1 and ISA2. The maize protein functions in Arabidopsis leaves to support nearly normal starch metabolism in the absence of any native ISA1 or ISA2 |
